Heavy load transporters present big technical challenges. Each single axle is steered by an IMO Slew Drive requiring the maximum axial, radial and tilting moment capacity. The WD-H 0300 with steering torques of 27000 Nm is an excellent solution.
In May 2004 the world record for the heaviest load moved on wheels was claimed with this Self Propelled Modular Trailer (SPMT). The trailer was equipped with a total of 470 axle lines and 1880 wheels.
The patented IMO-Slew drives, used as steering gear, took their share in reaching the world record.
