Back-Up Drive Equipment

The Coldest Journey is the first ever attempt to cross the Antarctic continent during the polar winter, using two Caterpillar bulldozers in conditions which could reach -90 ̊C.

The Finning customisation team contacted Bosch Rexroth due to the need to provide a robust back-up heat generating system for the specially engineered caboose living quarters. Due to the immovable departure deadline for the project, the production of the valves needed to be turned around within days of the Finning order. Bosch Rexroth met the tight deadline and provided detailed component drawings which allowed the customisation team to accurately assess the optimum position to mount the valves and hose routings, before the parts arrived, saving Finning valuable time. Due to the quick response, Finning then asked for drive motor and flow control valves to drive the generators at a constant 1500rpm at any engine speed.
