During the last 30 years we have provided gears for various types of contractor machines. i.a. large snow-clearing machines for airports, forestry machines, hydraulic propulsion units for off-road trailers, mining drilling rigs and pneumatic drilling equipment.
The gears on the various contractor machines differ very much. Both large and heavy case hardened and ground gears, gears for more compact planetary gears, spline shafts, spline bushings and toothed couplings are used.
The requirements for the gears typically range from Class 6-8 according to DIN 3962 (AGMA 9-11) according to place of use, how much power being transmitted, and how fast they run.
