Trelleborg to provide a ‘step change in composite bearings’ with Orkot C620

Trelleborg Sealing Solutions says it is pushing the boundaries of composite technology with the launch of Orkot® C620, an innovative ultra-low friction bearing material with five times the compressive strength of other Orkot materials for off-highway applications.

A high-specification thermoset composite, Orkot C620 meets the requirements of the most demanding high-load applications across all market sectors, including off-highway, Trelleborg says. Though strong and light, it withstands high loads and stresses over a long service life.

Mark Hampton, Product and Innovations Manager, says: “Orkot C620’s optimised properties provide customers with a step change in composite bearings, offering a unique combination of ultra-low friction and a compressive strength of 470 MPa, five times the strength of standard Orkot materials. It is both stronger and has better friction characteristics than competitor composite materials, and can even challenge many metallic bearings for strength, offering industries such as aerospace the lighter, lower-friction solutions they increasingly demand.

“Featuring a strong glass fibre backing with a low-friction Orkot lining, it builds upon regular Orkot composite formulations with a unique compound where the properties of the different layers increase load capacity and strength. It does this without compromising weight while reducing friction and eliminating maintenance to maximise efficiency and service life.”

Because of its unique characteristics, Orkot C620 is an attractive solution for the demanding high-load applications of off-highway equipment like excavators, Trelleborg says. It withstands high loads in boom pivots when excavating large volumes of material. Its low stick-slip means that hydraulic cylinder pivots bearing heavy and valuable loads can be more efficient and operate more smoothly, while its durability extends the service life of track rollers and undercarriages in dynamic applications by reducing wear.

In bucket linkages it resists impacts of up to 200 KJ/sq.m, demonstrating resilience in applications that experience shocks and vibration, the company says. Orkot C620 wear rings in hydraulic cylinder rod guides reduce stick-slip to manage an excavator’s sharp and repetitive movements.

Orkot C620 has been extensively tested for its mechanical properties, thermal expansion and fluid compatibility, and meets standards including AS 9100, ISO 9001, ISO 14001 and ISO 45001, Trelleborg says.

MinRes takes delivery of Hitachi EX3600 excavator for Onslow Iron

Mineral Resources Ltd has taken delivery of a Hitachi EX3600 hydraulic excavator at its Ken’s Bore mine site, set to support its Onslow Iron project in Western Australia.

The brand new excavator was transported via four trucks, travelling 1,350 km from Perth, and will be used to construct haul roads, run of mine pad and mining broken stocks.

It made the trip along with a haul truck and drill – just some of the 15 haul trucks, three excavators and four drills that will work on site when the mine is fully operational.

MinRes’ A$3 billion ($2 billion) Onslow Iron project is, MinRes says, set to redefine mining in Western Australia, shipping around 35 Mt/y of iron ore from mid-2024. It is owned through the unincorporated Red Hill Iron Joint Venture, which is 40% held by MinRes, who will manage the project, with the other partners being Baowu, AMCI and POSCO.

Normet strengthens scaling and breaking market position with Rambooms, Marakon buys

Normet says it has agreed to acquire Rambooms Oy, a manufacturer and supplier of rock breaker boom systems, and Marakon Oy, a supplier of hydraulic hammers and excavator attachments for the construction and mining industries.

The Rambooms and Marakon businesses, with a manufacturing facility in Lahti, Finland, form the Marakon Group. The group has a wide customer base, and its products are found in most mining and construction markets, according to Normet. Marakon Group had 35 employees and net sales of €26 million ($27.8 million) in 2022.

Ed Santamaria, President and CEO at Normet, said: “Rambooms and Marakon are known for their high performing quality products. With the acquisition Normet strengthens its position in scaling and breaking as well as supports advancing towards higher levels of automation and electrification for the mining and construction industries. We look forward to welcoming the Marakon Group employees to Normet and supporting them in their future growth and development.”

Tomi Veijalainen, President of MRB-Holding Oy, added: “Throughout the past 40 years Marakon and Rambooms have grown together with both our business partners and employees. We feel trustful in the fact that this acquisition will allow for these shared success stories to continue. As this milestone marks a step towards new opportunities to advance and succeed, we are excited to follow the future accomplishments of both companies.”

The acquisition is expected to be closed this quarter, subject to the fulfilment of customary closing conditions.

Pre-production mining fleet starts to arrive at Greenstone gold project

Equinox Gold Corp says it is making good headway on its 60%-owned Greenstone project, in Ontario, Canada, with four Cat 793 haul trucks delivered to site and the first Komatsu PC-5500 excavator set for assembly this quarter.

The Greenstone project is being developed as a 60/40 partnership, respectively, by Equinox Gold and Orion Mine Finance Group, and is billed as being one of the largest gold mines in Canada, producing more than 400,000 oz/y of gold for the first five years and more than 5 Moz of gold over its initial 14-year mine life.

The project is now 35% complete and on schedule to pour first gold in the first half of 2024, Equinox says. As of June 30, 2022, 56% of total capital costs had been contracted and Greenstone had spent $315 million (26%) of its $1.23 billion construction budget (100% basis).

The earthworks were 48% complete, with plant site earthworks 76% complete, tailings storage facility (TSF) earthworks 29% complete and the Highway 11 realignment earthworks 39% complete. Structural concrete was 37% complete and structural steel 21% complete.

The company says pre-production mining should commence in the December quarter with the four Cat 793s (250-t) payload haul trucks and the first Komatsu PC-5500.

Equinox has also committed to mobile equipment lease financing of $78 million for the project, deferring approximately $53 million of initial capital spend, it says.

The Greenstone Mine plan contemplates construction of a 27,000 t/d processing facility and open-pit mining operation for the Hardrock deposit. The process plant consists of a crushing circuit, grinding circuit, pre-leach thickening and leaching, carbon-in-pulp circuit, carbon elution and regeneration, electrowinning and gold refining, and tailings disposal, with overall gold recovery of 91.2%. Mining will use conventional open-pit blast, load and haul techniques, with the 2020 technical report also including the potential for automated blasthole drilling.

Christian Milau, CEO of Equinox Gold, stated: “The Greenstone team has done great work staying on schedule and on budget, despite the challenges of starting construction during COVID and dealing with inflationary and supply chain issues. The independent quantitative risk assessment of our schedule and construction budget has provided additional comfort that we’re on track to deliver the project as planned in the first half of 2024.

“Excellent earthworks progress during the winter months means we can focus on concrete foundations and steel structures during the summer and fall and enclose the majority of buildings before year end, which will allow us to maintain productivity during the winter months.”

Upcoming construction milestones include:

  • Delivery and assembly of pre-production fleet of four trucks and excavators: Q2-Q3 2022;
  • Permanent water effluent treatment plant ready for use: Q3 2022;
  • Commence installation of gensets in power plant, power building enclosed: Q3 2022;
  • Start of pre-production mining: Q4 2022;
  • Truck shop, warehouse, process plant (HPRG, crushing and main buildings) ready to enclose: Q4 2022;
  • Leach tanks installed: Q4 2022;
  • Ball mills received: Q1 2023;
  • Crushers installed: Q3 2023;
  • TSF complete: Q4 2023;
  • Highway 11 realignment complete: Q4 2023
  • Commissioning: Q1-Q2 2024; and
  • Gold pour: Q2 2024.

Marathon taps Caterpillar Finance for equipment lease at Valentine gold project

Marathon Gold Corp says it has executed a credit-approved commitment letter with Caterpillar Financial Services Limited for equipment lease financing related to the development and operation of the Valentine gold project in Newfoundland, Canada.

The commitment letter with Cat Financial contemplates $81 million of equipment leasing for Caterpillar trucks, excavators, graders, loaders and dozers, for the purpose of loading, hauling, road maintenance, waste dump maintenance and primary pit support for the project.

The lease will be available to the company upon release of the project from its federal Environment Assessment process, review of the project’s updated feasibility study, satisfaction of a cost to complete certification and other customary conditions, Marathon Gold said.

An April 2021 feasibility study outlined an open-pit mining and conventional milling operation at Valentine with a 2.5 Mt/y processing rate over a 13-year mine life with a 31.5% after-tax internal rate of return and initial capital costs of C$305 million ($237 million). The project has estimated Proven reserves of 1.40 Moz (29.68 Mt at 1.46 g/t) and Probable reserves of 650,000 oz (17.38 Mt at 1.17 g/t).

Matt Manson, President and CEO of Marathon, said: “We are very happy to be announcing today our equipment leasing commitment with Cat Financial, another significant milestone in our project financing arrangements for the Valentine Gold Project. This agreement will provide financing for the project’s mobile mining equipment through project development and into the first several years of mining operations at an attractive overall cost of capital for Marathon.”

The lease announcement follows hot on the heels of Marathon Gold signing a Letter of Intent with SNC-Lavalin to complete detailed engineering for the project’s mill and major facilities, and develop related equipment and construction packages.

NRW cements Karara Mining services contract

NRW has followed up on a letter of intent with Karara Mining Limited for mining services works at the Karara Iron Ore mine in Western Australia, sealing a formal contract with the company.

The contract value is circa A$702 million ($502 million) over a five-year duration, with the project workforce averaging an estimated 250 personnel.

Located 200 km southeast of Geraldton in the Shire of Perenjori, Karara is the largest mining operation and the first major magnetite mine in the Mid West. It produces a premium, high-grade concentrate product for export to steelmakers.

With an expected mine life of 30-plus years, Karara’s operation includes a large open-pit mine, complex ore processing and beneficiation plant and significant infrastructure and logistics networks.

The works to be performed include load and haul, drill and blast and run of mine re-handling with the drill and blast component to be undertaken by NRW’s wholly owned subsidiary, Action Drill & Blast Pty Ltd.

In addition, the work includes train loading and rehandling of the product stockpiles together with miscellaneous dayworks at the mine site, camp and access roads.

Key mining equipment required for the project including three 600 t excavators and a fleet of 220 t trucks is being progressively mobilised to site for commissioning, with works commencing in March 2022.

NRW Chief Executive Officer, Jules Pemberton, said: “I am delighted that NRW has now been formally awarded the contract and I look forward to a long and successful partnership with Karara Mining.”

Karara Chief Executive Officer, Changjiang Zhu, said: “NRW is an established Western Australia-based mining and civil contractor with extensive open-cut mining experience gained through a number of successful mining operations in the state. Offering new prime equipment, NRW has the capability to undertake the entire Karara scope of work comprising a broad range of mining, construction and engineering services. We look forward to commencement of mining services early next year.”

Berco’s mining undercarriage transition takes shape in Copparo

With the opening of Berco’s new R&D facility in Copparo, Italy, the manufacturer and supplier of undercarriage systems and components has cemented a growth plan that could see it gain further market share in both its OEM and aftermarket segments and expand its product range for mining applications.

Covering 2,000 sq.m, the new department is located beside the entrance of the company’s main plant, a building that captures 101 years of company history and is being updated with a new vision backed by parent company thyssenkrupp.

The new R&D hub is home to the T&I (technology and innovation) team, which will be divided into two subgroups: the metallurgical laboratory and product engineering.

Officially opened on November 17 – IM and other trade press members received a sneak peek a day earlier – the facility houses state-of-the-art machinery, specifically developed to advance the company’s strategic plans for the future.

These strategic plans date back to early 2018 when, as part of the Forged Technologies business unit, Berco developed a strategy that encompassed “lean manufacturing” and the company’s unique know-how, according to Berco CEO, Piero Bruno.

“We have a unique know-how of metallurgy within Berco,” he said during last week’s press event. “We, as part of Forged Technologies, represent a strategic pillar for thyssenkrupp. We are a core business within the group (thyssenkrupp Industrial Components).”

The latter is an important point considering the divestments thyssenkrupp has been making in recent years – which includes plans to offload its mining business to FLSmidth. Berco has been safeguarded from this corporate activity, evidenced by the recent investment in its facilities.

Berco is a rarity in the mining sector; a company able to deliver the full undercarriage (chains, rollers, drive sprockets, track adjusters, track chains or idlers) for large dozers and excavators, for both aftermarket applications and equipment manufacturers. Mining and construction represent more than 30% of its sales currently, with on-highway trucks and passenger vehicles taking up around 60% of the remaining share.

There are other undercarriage suppliers on the market, but few of them have 32,000 t and 16,000 t screw presses capable of forging the scale of products needed in heavy-duty mining applications. Even fewer have the expertise to take an industry-standard product and tailor it for longer life and increased uptime in such applications.

This puts Berco in an interesting position where, in some instances, it is producing components or complete systems that compete directly with the equipment manufacturers.

In the instance of the Cat 6020B hydraulic mining shovel, Berco has built a complete undercarriage system as an alternative to the OEM equivalent on the market.

Outside of dozers and excavators, the Berco name has also been seen on components fitted on apron feeders and bucketwheel excavators. It may also soon find its way into conveyors (on the aftermarket side) and drill rigs (for equipment manufacturers), in addition to new excavator and dozer models.

Going platinum

When it comes to mining equipment innovation from Berco, one only need look at the Platinum line of products, which are focused solely on performance in the field and operating costs.

The new Cat 6020B undercarriage (below, right) is the most recent addition to this line, also representing the first “non-captive” range available to purchase, according to the company.

With this product, Berco becomes the only company – aside from Cat – currently capable of providing what it says is a full and significantly more affordable variety of undercarriage replacement components for this particular machine.

Launched in 2014, the Cat 6020B is a 230 ton (224 t) excavator at the high end of the mining range. Depending on the abrasiveness of the soil, undercarriage components need to be replaced every four-to-five years, according to Berco, meaning there are significant numbers of this model currently due undercarriage maintenance.

For the Cat 6020B hydraulic mining shovel range, Berco used a “reverse engineering” process to deconstruct the original equipment components. Three-dimensional material scanning was carried out to gain a complete understanding of the initial design criteria, while laboratory analysis determined the materials used as well as the heat treatments and microstructures.

Berco-originated innovations that feature on this non-captive undercarriage system include the BPR2™ (Berco Positive Pin Retention2™ system) to improves the working lifetime of the components through mechanical locking of the link to the pin; a newly designed track link for the track chain with a 350 mm pitch produced using the “drop forged” process made from mild carbon steel with boron and chromium additives; and track bushings with 60 HRC hardness steel that have a high resistance to wear.

Additionally, the track roller can, because of its lubrication and seal features, adopt an “all-weather” configuration ranging from -40°C to 50°C.

The first of these new undercarriages is due to be dispatched from Copparo by the end of the year, destined for a customer in Africa.

This type of aftermarket strategy – where the company identifies a product area and develops an improved industry solution in line with expected maintenance intervals – could end up being used for future products if proven successful, Francesco Grenzi, Executive Director of R&D Department, told IM.

Grenzi and his new T&I team are integral to making this happen.

Having in the past four years added five new patents to the Berco offering, the R&D head is keen to develop products that outperform the industry standard and are tailored to the application at hand.

He can already point to several success stories in the dozer and excavator categories even before the first 6020B goes out the door.

For example, one of the company’s Platinum line undercarriage systems for dozers is outperforming the OEM equivalent by up to 25-35%. It performs in an extremely consistent manner for applications used in different conditions such as hard rock, coal or copper mines. Platinum line products are available along the complete mining dozer range, from 350 hp (261 kW) to 1,000 hp crawler dozers.

Other Platinum line products already on the market include high strength track link, ground engaging tools and its Robustus (ROtating BUShing Track Undercarriage System) solution.

Diego Buffoni, Head of Aftermarket, said these products represent a “niche” for the company when compared with the thousands of components and systems Berco produces on an annual basis, but their development also provides “an open door” for other sales.

“The Platinum line will contribute to growth, but it will not be the main driver,” he said. “It will help with our marketing presence, though…where we are able to show that Berco has a solution for every application worldwide.”

The development of such ‘best of breed’ solutions will have a knock-on impact on all the products that come out of Copparo, according to Bruno.

“If you look at F1, for example, you can see what manufacturers can produce for high-performance sports cars when budgets are not scrutinised or restricted to the same extent as they are in traditional markets,” he told IM.

“We see the Platinum line as potentially uplifting the wider Berco portfolio, which will also have a positive impact on the products going to our OEM customers.”

Automation and digitalisation

Observations like this are now being backed up by an increased focus on digitalisation and remote monitoring of Berco products.

This starts with digital records of tests in the new R&D facility – where there is a benchmark room, a metallurgical lab, a revamped roller test bench, updated rubber testing machines able to perform cryostatic tests for anticipated performance at very low temperatures and a new spectrometer machine, to name a few innovations – through to automated data analysis during the manufacturing process to ensure products are matched to their final applications, and finally 3D geometric scans for product benchmarking against the competition.

The company’s Bopis Life system has now moved onto generation two where undercarriage measurement and wear conditions are monitored remotely using ultrasonic probes. This enables predictive maintenance of critical parts, while supporting fleet management, the company said. Berco currently has 15 licences for this system, backed up by 22 ultrasonic probes that provide such feedback. This is some improvement on the ‘traditional’ monitoring of undercarriage components that normally takes place on mine sites with callipers and clipboards.

Berco is also looking to add in-built sensors to track links to provide real-time wear performance data that customers and company technicians can use to improve machine uptime. These are termed “smart undercarriages”.

The digitalisation and innovation do not end here.

What is perhaps most impressive about the 101-year-old company is its willingness to change with the times.

In 2018, it brought in Mario Andaloni as Chief Operating Officer to steer a €40 million ($44.9 million) project to refurbish and invest in the company’s facilities in Copparo.

This massive job has seen the company de-centralise its energy sources to a much more efficient and modern heating system that will achieve a 13% decrease in gas consumption in the first year alone; re-design the steel yard in line with a ‘lean manufacturing’ methodology; reorient its forging, heat treatment and shoes areas; and significantly reduce the company’s waste footprint. A more strategic and efficient use of robots in the manufacturing process is also coming to the fore.

The principles that Andaloni has instilled are set to pay off when it comes to the output of equipment.

When asked what impact the project was likely to have on product turnaround times when completed in 2023, he said the aim was for products that required no forging or component additions to take five days to manufacture. When forging and components were added on, the target was 10 days.

“Currently we are around 20 days duration for the complete process,” he told IM. “Before we started this new lean manufacturing strategy, we were around 35 days to make products; that was without forging included.”

These durations don’t include the raw material deliveries into Copparo and transport requirements from the facility, but they are a major signal of the company’s intent to make a real impact on the undercarriage supply chain.

The initiation of an e-commerce platform for Berco aftermarket dealers across the globe – due to launch in late January – will make the company “more agile, more flexible, more in line with the needs of today’s global market”, Bruno said. It will inevitably capitalise on the work Andaloni and his team have been doing on optimising the factory workflow, too, allowing customers to see product availability as well as potential lead times.

All these developments are setting Berco up to capitalise on increased demand from both the mining and construction sectors, with it anticipating future sales increases across both its aftermarket and OEM segments into the future.

On the latter, Buffoni said there was potential to address a market worth some €23 billion in the future with key production additions and developments backed up by an aftermarket organisation that is proactive and flexible. He currently saw Berco playing in a €2 billion market, divided 50:50 between mining and construction.

His counterpart on the OEM side, Fedele Salvatore (Head of Sales OEM), said there were many opportunities to grow its own 13% market share in the €2 billion undercarriage global original equipment market through a “funnel” approach that included more engagement with existing and new original equipment customers, entries into new regional markets in key areas such as Asia and further diversification of the product line.

A re-focus on providing complete undercarriage systems, as opposed to components, would also go some way to achieving growth aims.

What is clear is that the Berco name, 101 years after its birth, has a bright future in the mining segment. By the end of 2023, it will have the equipment and infrastructure to serve a market in need of robust solutions for today’s and tomorrow’s mines.

Baidu Research Robotics and Auto-Driving Lab present autonomous excavator concept

Researchers from Baidu Research Robotics and Auto-Driving Lab (RAL) and the University of Maryland, College Park (UMD) say they have developed a real-time mapping approach for autonomous navigation of excavators on complex terrains, named Terrain Traversability Mapping (TTM), that is being showcased at MINExpo 2021 this week.

Using TTM, an autonomous excavator can navigate through unstructured outdoor environments consisting of deep pits, steep hills, rock piles and other complex terrain features, according to the companies involved. This is the first complex terrain processing approach developed for heavy-duty excavation machines, they say.

To enable autonomous excavators to handle complex terrains, the researchers developed an efficient learning-based geometric method to extract terrain features from RGB images and 3D point clouds and incorporate them into a global map for planning and navigation.

The method uses physical characteristics of the excavator, including maximum climbing degree and machine specifications, to determine the traversable area, adapt to changing environments and update the terrain information in real time.

In addition, these researchers have prepared a “novel” autonomous excavator terrain dataset, which consists of RGB images and LiDAR point clouds from construction sites with seven different categories based on navigability. This integrates the mapping approach with planning and control modules to continuously improve the autonomous excavator navigation system, they say.

“Experiments showed that while using TTM, an excavator can navigate through unstructured environments with a much higher success rate compared to existing planning schemes,” the companies said.

The new TTM technique comes on the heels of another innovation Baidu RAL and UMD co-developed this June – an autonomous excavator system (AES) that can perform material loading tasks for 24 hours without any human intervention, while offering performance nearly equivalent to that of an experienced human operator.

ERG to acquire Hitachi EH4000 AC-3 trucks, EX5600E excavators for SSGPO operation

Eurasian Resources Group (ERG) has signed a cooperation agreement with Eurasian Machinery LLP, the official provider of Hitachi specialised equipment in Central Asia.

The agreement will see 12 Hitachi EH4000 AC-3 dump trucks and two Hitachi EX5600E hydraulic excavators delivered this year to the Kacharsky open pit iron ore mine, part of ERG’s Sokolov-Sarybai Mining Production Operation (SSGPO), in Kazakhstan.

This stands as one of the most significant acquisitions of specialised mining equipment in Kazakhstan’s history, according to ERG.

The new equipment, boasting 220 t lifting capacity, will be used for overburden operations and the transportation of iron ore, and is part of a large-scale reconstruction of the entire Kacharsky site aimed at a considerable increase in iron ore production volumes at SSGPO, ERG says.

The delivery of the specialised equipment will offer remarkable increases in load capacity and provide further advantages when working on a large scale, according to the company.

In addition to delivering specialised equipment, Eurasian Machinery will perform a wide range of maintenance works, including the construction of service infrastructure and the supply of necessary spare parts over the next 10 years. They will also offer specialised simulator training to ERG’s drivers.

As part of the agreement, which will be carried out according to the maintenance and repair contract principles, ERG will purchase up to 50 units of specialised mining equipment.

Berco bolsters Excavator Line with Cat 6020B undercarriage replacement range

Berco, a leader in the manufacturing and supply of undercarriages and components to OEMs and the aftermarket, has reached another milestone with the launch of its complete undercarriage replacement range for the Cat 6020B hydraulic mining shovel.

Developed specifically for the high-quality demand mining segment of the aftermarket, this is the first “non-captive” range available to purchase, according to the company. This means that aside from Cat, Berco is the only company currently capable of providing a full and significantly more affordable variety of undercarriage replacement components for this particular machine, Berco said.

Launched in 2014, the Cat 6020B is a 230 ton (224 t) excavator at the high end of the mining range. Depending on the abrasiveness of the soil, undercarriage components need to be replaced every four-to-five years, according to Berco, meaning there are significant numbers of this particular model currently due undercarriage maintenance. This number, moreover, is forecast to grow in the coming years.

To meet this demand, Berco is supplying a full range of undercarriage components including the chain, the bottom rollers, the top rollers, the drive sprocket and idlers with supports. Everything is set to be available from September onwards.

“These machines must be capable of working in harsh environments for 20-24 hours a day without stopping, because when the main excavator on a site is out of service, it has a direct knock-on effect on all of the secondary machines,” Diego Buffoni, Head of Aftermarket Berco, said. “We are particularly proud of this new range launch, which will offer a great business opportunity for our partner distributors worldwide. On top of Berco’s acclaimed high quality, which it provides, it also signifies the path we are on, which is to supply comprehensive and affordable solutions to all aftermarket customers.”

For the Cat 6020B hydraulic mining shovel range, Berco used a “reverse engineering” process to deconstruct the original equipment components. Three-dimensional material scanning was carried out to gain a complete understanding of the initial design criteria, while laboratory analysis determined the materials used as well as the heat treatments and microstructures.

“Having gained a full understanding of all of the components in question, company engineers then proceeded to develop their very own Berco-quality aftermarket undercarriage system, which is further boosted by the addition of another Berco innovation: BPR2™ (Berco Positive Pin Retention2™ system),” the company said. “This improves the working lifetime of the components by mechanically locking the link to the pin which results in the avoidance of ‘end-play generation’ and ‘pin walking’ in an undercarriage.”

For the track chain, a newly designed track link with a 350 mm pitch was produced using the “drop forged” process made from a mild carbon steel grade with boron. Unlike the original equipment product, however, the chemical composition of the Berco version is enriched with chromium to increase tensile resistance. In addition, the track bushing has a high resistance to wear. With 60 HRC hardness, it can contain pitch elongation, according to the company. The case depth has also been increased by 20-25% when compared with the original. The track pin, moreover, has deeper case depth and higher core hardiness, resulting in an improved bending load resistance, Berco said.

The track roller can, because of its lubrication and seal features, adopt an “all-weather” configuration, ranging from -40°C to 50°C. Additionally, three top rollers without a central flange support the heavy weight of the chain, and the oil filling hole has been moved to the outer collar to ensure full access to it.

With Berco’s Dozer Line already complete, the launch of its range for the Cat 6020B hydraulic mining shovel brings the company closer to finishing its Excavator Line too.

Accounting for a large portion of all aftermarket sales, Berco says the mining market segment is of particular importance to it. The company is now looking to further strengthen its position by extending its mining ranges and becoming the only high-quality alternative to OEM components.
