GHH India’s contract mining arm wins plaudits for work with Hindustan Zinc

GHH India’s recently established contract mining arm, GHH Bumi Mining Service, has notched up its first significant award, being recognised by Vedanta Group/Hindustan Zinc Ltd (HZL) for the work it is doing at the Zawar Mala zinc-lead underground mine in Rajasthan, India.

In a recent online event, GHH Bumi Mining Service, established late last year, was named as the recipient of the Best Performing Business Partner by the companies.

The award winner was chosen out of all business partners and recognised a job well done, GHH said.

Over the last six months, GHH Bumi has been carrying out contract mining at Zawar Mala, and was presented the award, GHH says, based on excellent performance involving all contract mining activities, including those related to safety, production and asset optimisation.

Since January, GHH BUMI has been responsible for production and mine development with more than 350 employees at Zawar Mala. For this purpose, the company has access to more than 20 LHDs, dump trucks and drilling rigs from the GHH Group.

Dr Jan Petzold, CEO of GHH Group, said: “With this award, we as GHH Group see ourselves confirmed in our efforts as a reliable business partner for HZL – a cooperation that started almost four years ago with the supply of mining machinery and has resulted in being awarded as mining contractor and OEM.

“This is a special incentive to be able to conclude the second mine developer and operator contract with HZL, which is currently in preparation.”

The latest generation of GHH mining equipment, with its new dump truck MK-42, LF-14 and LF-10 LHDs as well as two FM 2.3 boom drill rigs from GHH group company, Mine Master, are on their way to India and are expected to be on site beginning of August, GHH said.

GHH says GHH Bumi is also currently working on preparing for the expansion of the Mochia Balaria Decline project, where a rapid development proposal is under way.

GHH receives Red Dot award for MK-42 underground dump truck

GHH has been awarded a Red Dot Product Design award for its new 42 tonne underground dump truck.

The MK-42 can carry up to a maximum of 45 t with the dump truck tray capacity ranging from 19 cu.m up to 24 cu.m.

What’s more, the truck comes with a best-in-class power rating of 460 kW. It also has a class-leading turning radius and dump angle (of 68°) for improved performance and less material adhesion in the tray, the company says.

“The truck boasts optimal traction and higher driving comfort thanks to oscillating articulation and a front axle suspension system,” GHH says. “The MK-42 has a large, ergonomic ROPS/FOPS certified safety cabin with high performance air conditioning and air filtration. The pressurised cabin is noise and dust isolated with no high pressure hoses inside, and includes a strategically placed trainer seat for on-the-job operator training.”

GHH, together with Studio Heikki Naulapää Oy, created the baseline methodology and design philosophy for the MK-42 from which the GHH team developed the truck.

“This dump truck has been designed in collaboration with operators and miners in order to ensure the most fit-for-purpose product with best-in-class operator comfort and safety in mind,” the company said.

“The powerful, rugged product design lends itself not only to an extremely comfortable ride, but also provides for high productivity while maintaining low operating costs. The truck is strong on the inside and, through advanced industrial design, is also visually extremely appealing on the outside with the clear product colouring providing for maximum visibility in underground mining/tunnelling operations.”

On those companies receiving a Red Dot award, Red Dot CEO, Professor Dr Peter Zec, said: “The winners of the Red Dot Award have proved that they have created excellent products worthy of winning an award. The products won over the jury not only through their aesthetic, but also thanks to their incomparable functionality. With their designs, the award winners are setting new standards in their industry. I wish to congratulate them most sincerely on their success.”

The Red Dot Award: Product Design offers designers and manufacturers from all over the world a platform for assessing their products. In 2020, designers and companies from 60 countries entered more than 6,500 products in the competition, according to Red Dot.

The international jury comprises experienced experts from different disciplines and has been convening for around 65 years to select the year’s best designs.

The adjudication process lasts several days and is based on two essential criteria: the jurors test all of the entries for the aesthetic and materials selected, the level of craftsmanship, the surface structure, ergonomics and functionality.

“After intensive discussions, they make a decision on the design quality of the products,” GHH explains. “True to the motto, ‘In search of good design and innovation’, only the best designs receive an award.”

On June 22, the MK-42 material will be added to the Red Dot Design Museum in Essen, Germany, where materials from all the award-winning products will be on show. The MK-42 will also feature in the online exhibition on the Red Dot website.

New GHH 45 t capacity dump truck about to enter underground market

GHH has developed a new 42 t payload dump truck that, it says, offers maximum drive power, improved turning radius, steep dumping angle and excellent ergonomics and safety.

The German manufacturer of heavy machinery for civil engineering, tunnelling and mining, which has roots that go back to 1758, has three other underground dump trucks in its underground mining portfolio (in addition to two within its low profile dump truck offering and one within its flameproof portfolio) spanning 15-35 t payload applications. The new truck is the largest in its portfolio.

The new MK-42 offers an up to 45 t payload, 19-24 m³ dump body capacity, maximum drive power, a great turning radius, improved dumping angle and excellent ergonomics and safety, according to the company. It has a streamlined, innovative product design, which just received the Red Dot Design Award, GHH added.

The 460 kW Mercedes OM473 forms the engine base, fulfilling the latest EU Stage V emission standards. GHH also offers Tier 3 and 4 versions for less regulated markets, while an alternative Volvo Penta TAD1651 or 1671 engine option is available.

The vehicle rests on Kessler axles with oscillating articulation and front axle suspension, while the power is transmitted by a converter and gearbox combination from the Dana 8000 series.

Designed for use in harsh environments, especially in underground hard-rock mining applications, the MK-42’s dimensions are surprisingly compact at 3,062 x 10,535 x 2,719 mm (WxLxH). A steep dumping angle of 68° leads to high efficiency productivity and improved cycle time, according to GHH.

The company said special emphasis was placed on a safe and simple design, with low maintenance and repair costs, and operator safety and comfort kept in mind through the entire design process. The ROPS/FOPS certified cab is ergonomically designed to be spacious, quiet, pressurised and effectively air-conditioned to ensure maximum operator comfort while minimising fatigue, GHH says. The strategically placed trainer seat, meanwhile, provides for effective operator training.

The new MK-42 fits seamlessly into the manufacturer’s range of dump trucks and is the perfect haulage partner for GHH’s LF-14 loader, with the combination of the two offering three pass loading, GHH said. Extensive consulting, aftermarket support, parts sales and technical training are just a few of the services GHH offers to all customers worldwide.

Global sales will start shortly as the prototype truck enters its final stage of rigorous testing, GHH said, which added that a special version, the MK-A45, will be marketed exclusively for the Russia market.
