Weir’s ESCO division says it has extended its Nemisys mining tooth system to a new range of excavators.

The expanded Nemisys offering serves as a direct upgrade and replacement for the SV2® system and competitor weld-on systems for plate lip hydraulic excavators, it said.

Earlier this year, the company introduced the Nemisys N70 Lip System for hydraulic excavators as it looks to expand the tooth system’s reach beyond the large mining shovels, large excavators and wheel loaders it was initially developed for.

This latest addition will see the mining tooth system support 160 ton (145 t), 200 ton (181 t) and 250 ton (227 t) excavators.

“Operating on over 700 machines worldwide, the Nemisys system has demonstrated market leadership in reliability, site safety and enhancing machine performance,” the company said.

ESCO says the Nemisys system features hammerless locking mechanisms for greater safety and easy replacement, while the slim contoured profile improves bucket loading and reduces fill energy.

“The system is also known for reducing or eliminating unplanned downtime, providing major improvement in cost reduction and balancing machine maintenance cycles,” it said.

CR is preparing a new addition to its DecaEdge™ range of cast lip systems for large wheel loader buckets, with the new product due for public release by the end of the year.

The new DecaEdge DE2553 cast lip will complement the existing range and suit large mining wheel loader buckets with capacities between 14 cu.m and 20 cu.m, according to the company.

DecaEdge leverages the experience of CR’s RazerEdge™ cast lip range which revolutionised the market for 100 t to 400 t excavator lip and ground engaging tool (GET) systems, the company said. CR already has two lips in the market for the Komatsu L1850 and L2350, WA1200 and Cat 994 wheel loaders.

With over 160,000 combined operating hours and counting, a DecaEdge lip can last for up to 25,000 operating hours with no major rebuilds, according to the company. The system removes outdated plate lip features by employing integral cast noses and better material placement to achieve plane alignment and spade angle optimisation, delivering an over 33% reduction in total cost of ownership of the lip and GET system, according to CR’s General Manager of Product Management, Quintin Nienaber.

“It also eliminates the need for wear blocks and wear packages,” Nienaber says. “The specially designed teeth and shrouds are designed to also protect the lip, which means that every time a ground engaging tool is replaced, the underside wear package is refreshed, simplifying the maintenance process and reducing the demand on maintenance teams,” Nienaber says.

CR said the DecaEdge DE2553 is anticipated to uphold the durability and maintenance savings benefits experienced with the current DecaEdge range.

“CR is excited to broaden the range of this revolutionary technology,” it added.

Caterpillar bolts on new robust GET for large LHD buckets

Caterpillar is introducing a heavy duty bolt-on half arrow ground engaging tool (GET) for large underground loaders working in extreme applications.

The BOHA65 joins a complement of Cat BOHA GET designed for the entire line of Cat LHDs, the company says.

BOHA65 features extended wear life. For Example, BOHA65 segments for a Cat R2900 LHD have 35% more wear material than BOHA50 for the same loader. Trials in a hard-digging block cave application in Australia indicate that BOHA65 delivers extended, productive life in proportion to the additional wear material.

The entire line of Cat BOHA GET are designed for high abrasion applications where weld-on GET experience high wear rates. “With a proven and reliable retention system, the bolt-on GET offer more wear material that is also more abrasion resistant than standard weld-on GET,” the company says. “Testing has shown an average of more than 40% additional wear life compared to weld-on options.”

The bolt-on design enables simple and fast removal and replacement. After the base edge has been welded to the bucket initially, BOHA installs with two or three bolts per tip, according to Cat.

“An average weld-on set of cutting edges can require more than 20 hours to replace, and the process entails highly skilled work,” the company says. “BOHA takes 1 to 2 hours to replace and requires no welding. Ease of GET replacement encourages changeout before the base edge is damaged and downtime and costs mount.”

For example, a gold mine in western Canada calculated that Cat BOHA, compared with its traditional weld-on system, reduced bucket and GET cost per operating hour by 39%. BOHA GET had 2.5 times the life of the weld-on GET. Additionally, machine availability increased due to a 75% reduction in time to replace wear components, Cat added.

“BOHA GET enhance productivity in additional ways,” the company says. “The segments are designed to minimise carrying weight while keeping the bucket protected and, despite additional wear material, the low-profile front edge eases pile penetration and promotes fast bucket loading.”

Built-in wear indicators provide quick, ground level inspection of wear, while corner guards protect the sides and extend the service life of the cast corners used on larger loaders.

Additionally, corner segments have extended wear material designed to match the profile of Cat heel shrouds for ultimate protection in applications where cleaning up spillage is a frequent task, Cat says.

The BOHA GET are complemented by the use of additional Cat protection systems such as heel shrouds, mechanically attached wear plate systems, and wear bars.

CQMS Razer targets global growth in mining engineering, tech space as it becomes CR

CQMS Razer is looking to grow its mining engineering and technology footprint across the globe with a new name – CR – and direction that, it says, better aligns the company’s growing portfolio with the needs of its customers.

Already recognised across Australia’s mining industry for its surface mining solutions – including dragline products, cast lips and ground engaging tools – the CR brand change “reflects the company’s aspiration of growing its market reach and next-generation mining technology”, the company said.

The move follows several high-profile acquisitions of Seattle-based Thunderbird Mining Systems, a developer of market-leading blasthole drill optimisation technologies that complemented CR’s digital product range and its Titan 3330™ Load Haul Optimization technology, and California-based Berkeley Forge & Tool’s mining products business.

These have added meaningful scale, market connections and, importantly, deep mining knowledge from decades of product development and sales, the company says.

CR CEO, John Barbagallo, said the company’s growing product portfolio and prospective market opportunities meant it was essential to consider its reshaped business direction and how it plans to serve customers in the future.

“Today is an important day for CR as we launch our refined strategic direction and brand, a demonstration of our commitment to mining engineering and technology innovation and our capability to support our customers globally,” he said.

“The move to CR is very much about retaining the proud heritage of CQMS Razer, while providing us with a sharper and more focused brand, allowing us to add complementary businesses and products into the future.

“An important element of introducing the CR brand is to galvanise our brand and image for our employees. Together we are CR is a reflection of our strength and the reputation we have built over the last 40 years delivering reliable, innovative and customer-focused solutions for mining operations across the world.”

CR will include new product divisions that will better align the company’s growing portfolio to the needs of its customers, it said. This will see CR Mining, CR Digital and CR Contracts emerge, all of which are managed at a strategic level under the CR brand.

“Our experience and passion for what we do has seen us develop our business and become to a leader in our field, delivering outstanding results for our customers,” Barbagallo said. “This is a reputation we are keen to foster and build upon with our customers and markets worldwide under the new CR name.”

Weir Group says its ESCO division is working on an innovative solution that automates ground engaging tool (GET) changeouts, helping improve safety on mine sites.

In its annual report, released today, Weir said the GET Toolhead® would reduce the need for personnel to be in the pit, one of the most hazardous areas of a mine.

The new automated toolhead turns a hydraulic manipulator into a robot arm, according to Weir. It can securely grip and move GET, allowing it to replace parts weighing up to 500 kg.

“The movement of the toolhead is controlled remotely by a single operator, compared to teams of up to three people who would normally be required for a manual change out,” the company said.

Weir said in the report that it was continuing to commercialise this automated offering.
