Area of application


The BM-Volvo VHK 310 was a medium class, non- articulated motor grader built and developed for versatility in maintenance work and for demanding medium-heavy construction operations.


The BM-Volvo VHK 310 was a further development of the renowned VHK 115. The biggest differences were hydraulic transmission with a Powershift gearbox and a newly developed independently suspended rubber-sprung cab, amongst other things. One of the biggest benefits was thus for the operator, owing to the immensely im- proved operator comfort in the form of better visibility lower noise levels and better heat insulation, along with an opening front window. The machine exhibited here, serial number 6330, was built in 1971.
