The new MK-42, with a 45-tonne payload, is new top model in GHH’s product range. It is designed for harsh environments, especially in underground hardrock mining applications.
The German manufacturer of heavy machinery for civil engineering, tunnelling and mining can trace its roots back to the Gute Hoffnung Hütte ironworks in the 18th century.
It span out of a former industrial conglomerate, which included giants such as MAN, Roland and MTU. It became part of the Schmidt Kranz Group in 1999, alongside companies such as MineMaster and Hazemag.
The new MK-42, with 19-24 m3 dump volume, has just earned a Red Dot Design Award.
It is powered by an EU Stage V compliant 460 kW Mercedes OM473 engine and rests on Kessler axles with an oscillating articulation and front axle suspension. The power is transmitted by a converter and gearbox combination from the Dana 8000 series.
The new MK-42 fits into the manufacturer's range of dump trucks and partners with GHH´s LF-14 loader with three pass loading.
The prototype truck is now being put through the final stage of rigorous testing and is expected to be ready for sale before too long. There is also a special version of exclusively for Russia, named the MK-A45.
