A busy period in the aircraft hangar: the Boeing has to be ready for takeoff shortly. But before it can leave, the electronic engineers need some sensitive avionics from the warehouse, and the cabin crew have to change the covers and half the galley. This is a real challenge for the transport vehicles. They have to drive and lift pallets at the same time, without jolting or changing speed; accelerate without their wheels spinning on the hangar floors; brake accurately without damaging the goods; and all this with minimum fuel consumption. Every day, perfectly coordinated Rexroth components control thousands of fork lift trips.
The BODAS software controls the hydraulic pump on the basis of the electronic gas pedal position, current diesel engine output and hydraulic pressure. The all-important dynamic response can be switched according to specific circumstances to favor good handling performance or sensitive positioning. The electronics also ensure that the travel speed is unaffected when the working hydraulics are actuated. Smooth, jolt-free reversing thanks to BODAS greatly improves transport safety. The optional software packages that complete the Rexroth control system for fork lifts include fan, parking brake and brake valve control.
