Dellner Bubenzer showcases braking customisation expertise at Mongolia copper mine

Dellner Bubenzer, a manufacturer of high-performance disc and drum brakes, cylinders and accumulators for industries such as mining, is, once again, raising awareness of the importance of safety critical braking solutions.

The Dellner brand, the company says, has been synonymous with industrial braking and safety since Dellner Brakes was founded in 1941, but it has continually evolved, right up to and beyond the 2021 acquisition of Dellner Hydratech, the Danish supplier of high-end hydraulic systems, cylinders and accumulators for mining, wind, offshore, and marine applications.

The company says it has repeatedly delivered solutions to heavy-duty mining projects in recent years. In addition to its main market – material handling – the mining sector presents many challenges that require the company to respond with efficiency and precision, and produce targeted, tailor-made products.

“Mining is different to other markets, most notably because of the lead and project times in play, in addition to the demands placed on equipment at the point of use,” the company says. “Where a manufacturer of container handling equipment might complete production on a crane every single day, the largest mining companies…might be working to a site starting to mine a year from Dellner Bubenzer first being consulted. However, that point in time is non-negotiable and everyone has to deliver – on schedule and on budget.”

It is also not uncommon for component manufacturers to have service engineers on site for months at a time, which wouldn’t be the case in the material handling market, according to the company. And, while a lot of industries work to high duty cycles, mines are expected to be operational 24-hours-a-day, seven-days-a-week.

Mongolia, North of China, is just one of a number of country’s using Dellner Bubenzer’s solutions for mining. Here, the company referenced the supply of brakes for three gearless conveyor systems with an installed capacity of 2 x 5,500 kW each for a 7,100 t/h application in a copper mine.

The full scope of work included floating calliper brakes (model SFR50), brake discs, hydraulic power units, UPS, BCC3000 closed loop control systems, as well as the complete encoder technology.

The main parameters of the brake – pad wear, stroke (air gap) and brake pad temperature – are now continuously monitored, according to the company.

“The brakes stop the conveyor within 10 seconds in loaded or unloaded condition,” Dellner Bubenzer explains. “Depending on load, speed, etc, the HPU and control unit provide different braking levels and scenarios. The controlled braking process minimises the conveyor belt tension and reduces stresses in the connected equipment. The system is also able to perform the pre-programmed ramps and stopping curves after a power outage.”

Redundant controls and HPUs guarantee the highest system availability, while the environmental conditions required a compact setup of the brake units, the company says. The spring applied, hydraulically released, fail-safe brakes are able to equalise axial movement of the connected shafts.

Communication between the main PLC and BCC3000 happens via the PROFIsafe protocol, which integrates the relevant safety features while also monitoring the sub-functions, Dellner Bubenzer added.

Contamination prevention

High-end hydraulic cylinders and accumulators are central to Dellner Hydratech’s mining portfolio, the company says. These cylinders generate a pulling or pushing force, and are found, among other places, in earthmoving equipment at surface mines. Steering, bucket and lift cylinders can be found on a single wheeled loader. Accumulators, meanwhile, are a type of pressure storage hardware where an incompressible hydraulic fluid is held under pressure and applied mechanically.

An overarching concern with such technologies – where they are required to work in dirty, heavy-duty environments – is contamination. These systems have multiple components and, when they become contaminated, costly downtime can occur. In fact, over 70% of failed cylinders have broken down due to contamination and Dellner is contacted daily about inferior systems breaking for the same reason, it says.

All weld details must be optimised for high fatigue strength and to eliminate the risk of contaminating internal parts of the cylinder. Metal-to-metal gaps at welds must also be avoided, as dirt can be trapped and released when parts expand at high pressure.

Dellner says it recently improved the 800-hour lifetime of a cylinder by five times, ‘simply’ by removing the risk of contamination.

Dellner Bubenzer Germany is part of the company’s industrial business division, and is currently answering all enquiries regarding mining, supported by automation engineers, commissioning teams, and the firm’s research and development department. Sales, technical functions and commercial calculations all take place at the same facility too.

Dellner Bubenzer says it also recognises that proximity to the point of use is especially important to aftersales, locating its product development and manufacturing facilities across the globe to efficiently serve the mining industry. Presently, Dellner Bubenzer maintains manufacturing/service facilities and operational bases in several key regions, including Europe, Asia and North America. These global facilities are positioned to ensure proximity to major mining markets, facilitating streamlined production processes and prompt delivery of braking solutions to mining operations, wherever they might be, it says.

Caterpillar boosts payload, performance with new 995 wheel loader

Building on the success of the 994K, the new Cat® 995 Wheel Loader features up to 19% increased productivity than the previous model with its higher rated payload and 6% increase in hydraulic force with equal hydraulic cycle time, Caterpillar says.

This new loader delivers up to 13% lower hourly fuel consumption and offers up to an additional 8% efficiency gain when operating in Enhanced Eco Mode compared with throttle lock mode, according to the company. It is also up to 19% more efficient than the 994K in equal comparisons of throttle lock operation.

Enhancements to the front linkage include an improved casting design, increased weld size, larger bearings and pins, and profile changes for increased service life. New, larger capacity buckets available for the 995 incorporate an extended floor for fast loading, high fill factors reaching 115%, and excellent material retention. Buckets are interchangeable between the 995 and 994K.  

Built to the same size as the 994K but offering a higher rated payload, the new 995 enables a one-pass reduction when loading Cat 785, 789 and 793 mining trucks. This equates to up to a 33% increase in production and efficiency when loading the 785, up to a 25% increase with the 789 and up to a 20% increase with the 793.

The new 995 meets the global industry’s demand for high production and greater payloads with its powerful Cat 3516E engine offering configurations based on regional needs, meeting EU Stage V/US EPA Tier 4 Final or US EPA Tier 1 equivalent emissions, the company says. Its 39% torque rise ensures high lugging forces during digging and acceleration in high rim pull conditions.

Comfort and visibility

The redesigned next generation operator environment for the new 995 has 50% more legroom and boasts features that improve operator confidence while reducing fatigue. Its pressurised cab reduces vibration feedback, lowers sound levels and includes automatic temperature control. Providing shift-long comfort, its new electro hydraulic speed-sensing steering with force feedback automatically stiffens when traveling at higher speeds and softens as speed decreases to boost operator confidence.

Designed for visibility, the cab’s taller windshield provides a 25% increase in glass surface area and a 64% increase in wiper sweep area to better see the bucket. Two 254-mm colour LED monitors display machine control, operating functions and the electronic operator’s manual. A third 203-mm screen offers a dedicated view of the standard rearview camera and is upgradable to a multi-view camera system that offers 270° vision with rear object detection.

Access and egress to the cab along with all service areas being accessed from either ground level or a platform improves safety on the job. Wide stairs with full handrails on each side are positioned at a 45° angle for easy access. An optional powered access system – raised and lowered from either the cab or ground level enhances ingress and egress to and from the rear platform even further.

Confidence-boosting technology

Integrated with electronics, the new Cat 995 wheel loader offers flexible levels of information and technologies for a smart machine and more informed operator, maximising the productivity of both. Standard tip up prevention technology avoids unnecessary stress on the drivetrain and structural components by delivering full breakout forces while preventing the back tyres from significantly lifting off the ground.

New optional Autodig components automate three of the dig cycle’s most difficult parts in both rehandling and tough digging applications to improve productivity and reduce tyre wear.

Reducing tyre wear, Tire Slip Prevention reduces rimpull before the tyres are set and increases rimpull when downward force is applied. Auto Set Tires detects pile contact and automatically lifts against the pile to set the tyres and increase available traction, discouraging premature racking. Lift Stall Prevention manages rimpull in-dig to prevent hydraulic stall when lifting through the face, so the 995 spends less time in the pile.

An onboard interactive training tool, optional Operator Coaching measures and reports on individual operator behaviours that have an impact on efficiency, production and component life. Instructional videos provide training on measured behaviours, showing both the incorrect and recommended behaviours. Among 21 total monitored operating technique aspects, the system shows how to properly reduce tire rotation, avoid unracking in-dig, enter the pile with a level bucket, avoid excessive usages of the impeller clutch, reduce dump height and use the kick out.

Available Payload Overload Prevention improves productivity and efficiency by allowing a larger bucket to be used to achieve pass-match targets across a range of material densities without risk of overload. It is configurable to either stop or slow lift arms when the maximum allowed payload, including bucket weight, is exceeded.

Standard Vital Information Management System (VIMS) on the new 995 allows customers to connect directly to the machine to access a wide range of sensor information and enhanced machine data. Taking the guesswork out of asset management, standard Cat Product Link™ provides remote access to machine operating data via the easy-to-use VisionLink® interface. The 995 supports a variety of Cat MineStar™ solutions including Health, Guide and Terrain.

Reduced maintenance

Offering a 500-hour engine oil change interval and improved air filter life, the 995 spends more time working. The number of steering hoses has been reduced from 15 to 10 and tubes cut from 11 to one to improve steering system reliability. An enhanced service station provides access to functions like coolant and oil as well as level indicators, and it features a Cat battery charging connector and indicator lights for fuel tanks.

The loader’s redesigned pump bay improves access to transmission components, offers discharge ports on the side of the pumps and has simplified lines routed directly to the high-pressure screens. The bay includes a brake pump filter, implement pilot filter and implement discharge screens, and diagnostic ports are accessible from the front walk deck and pump bay. Ground line service now includes a steering pilot filter, transmission filters and steering pump discharge screen.

Austin Engineering makes management changes as it targets further North America growth

Austin Engineering Limited has announced changes to its senior management structure in an effort to grow its North American business.

Current Chief Operating Officer (COO), Graham Backhouse, has been appointed to the new role of Chief Strategy Officer. The role will primarily concentrate on developing a growth strategy for Austin’s North American business where Austin is focused on increasing market share for haul truck trays and, in particular, mining buckets, following the company’s acquisition of Australia-based Mainetec in 2022.

In the last 18 months, following several operational changes, Austin’s North American business has seen much-improved EBITDA margins, which are now at record levels, Austin said. The North American order book has nearly doubled since a similar period last year, further reflecting the success of those operations and highlighting the potential in this region.

Austin’s central North American hub is located in Casper, Wyoming. It is a large manufacturing facility supported by multiple final assembly partnerships. North America is a major global market for mining equipment and Austin sees the potential for further substantial revenue growth across its existing equipment offering, plus Mainetec’s products, including in its high-value dipper bucket products.

Vincent D’Rozario has been appointed as the company’s COO. He will continue to drive the Austin 2.0 growth strategy across the business and further embed the operating model that has seen substantial increases in delivered margins and order book growth across the business, the company says.

D’Rozario has held a number of executive positions and senior roles in a diverse range of sectors including engineering, commercial aviation, major project delivery, and environmental and waste management solutions. Most recently he was the Regional Managing Director APAC for CHC Helicopters, overseeing services to mining and energy companies and State and Federal Government entities. He is currently a Non-Executive Director of ASX-listed The Environmental Group, which provides waste and environmental solutions to the resources, health and heavy industry sectors.

Both appointments are effective January 20, 2023.

Austin CEO and Managing Director, David Singleton, said: “We are very pleased to strengthen the capabilities of our executive team with these two appointments, which will drive the next and substantial phase of our growth plan. We have made big strides across all business units over the last year and a half, with focused attention on our Australian and Indonesian businesses. We are very pleased to appoint Graham to develop and roll out a new growth strategy in North America. It is our second biggest market, and we are seeing substantially improved profitability and growth opportunity ahead. Central to that focus will be deploying more products developed in Australia into that region.

“We warmly welcome Vincent to the team as our new Chief Operating Officer. Vincent brings added capability to Austin through his diverse range of international experience in growing companies. We look forward to his contribution to Austin as we continue to grow our global business.”

Sandvik and Redpath to tackle underground mine safety and profitability with new pact

Sandvik and Redpath are aiming to improve safety and reduce underground mining costs through technology advancements, innovation, continuous improvement projects and standardised best practices under a newly-signed agreement guided by operational and relationship key performance indicators.

The five-year agreement includes Sandvik commitments on local presence and support, as well as an annual technology summit and factory training sessions. It will also standardise the use of equipment, leading to cost reductions and safety enhancements, the companies said.

“Sandvik Mining and Rock Solutions has long been a valued supplier of underground mining solutions to our global operations,” George Flumerfelt, CEO of The Redpath Group, said. “This mutually beneficial cooperation will help ensure Sandvik provides the same service experience and quality, independently of the geographic location and size of Redpath operations.”

Mats Eriksson, President of Sandvik Mining and Rock Solutions, added: “This agreement underlines the trust we have in our long-term relationship and further strengthens our good partnership with Redpath. Closer collaboration with Redpath’s business will enable us to deliver on expectations and optimise our product development.”

The two companies have worked on many underground mining projects together in the past and, last year, Redpath became the first company to receive and operate a Sandvik DD212 production drill in Australia, putting it into action at Silver Lake Resources’ Rothsay gold mine in Western Australia.

VDMA Mining notes German equipment turnover uptick in latest market outlook

The VDMA, which represents around 3,500 German and European mechanical and plant engineering companies, says Germany’s mining equipment sector continues to recover from the COVID-19-related downturn, with turnover for the first nine months of the year up by 18% to €3.75 billion ($3.9 billion).

“The mining industry is doing well at the moment, benefiting from a high order backlog,” the organisation said in its latest report. “In 2021, the manufacturers of technology for the extraction of raw materials achieved a total turnover of €3.18 billion in Germany as a production location.

“From January to September 2022, turnover of €3.75 billion increased by 18% compared to the same period last year. In the first three quarters, however, incoming orders declined by 26%.”

The industry hopes that the excellent mood and response at the bauma trade fair, in Munich, Germany, will be able to close the gap in incoming orders by spring and is counting on its technical expertise, especially in digitalisation, the VDMA noted.

Exports by mining equipment manufacturers in the period from January to August 2022 were 25% up on the previous year at just under €1.24 billion. VDMA Mining estimates that the industry will end the current year with a 15% increase in turnover.

The importance of modern mining technology for Germany as an industrial location has increased with the energy transition, according to the organisation.

Manufactburers are relying on digitalised and, where already possible, autonomous extraction and production processes – also in their own companies.

VDMA Mining added: “The bureaucratic obstacles, such as the German Supply Chain Act, which is ahead of the future EU law and can hardly be implemented, a shortage of skilled workers and the negative attitude towards mining are challenges that must be overcome in order for Germany to have a future as a high-tech location.”

Dr Michael Schulte Strathaus, Chairman of the VDMA Mining Executive Board, said at the Mining Industry Meeting in Essen, Germany, on November 17: “In addition to all the political and economic uncertainties we are currently facing, we must not lose sight of the fact that a sustainable industrial location in Germany is also a guarantor of social stability and our democratic system. Modern mining equipment secures our supply of raw materials and is, therefore, indispensable.”
