Abstract
A remote driving system (40) for use on a material handling vehicle (10) having a rotatable upper structure (12) including means for driving said material handling vehicle (10) through powershift transmission. A hydraulic power supply (50) is provided on the upper structure (12) and the output of which is controlled by an operator in the excavator cab (32) to be supplied to the hydraulic motor (44) supported on the main chassis (26). The hydraulic motor (44) is connected to provide power input to the automatic transmission (34) for forward or reverse driving of the vehicle (10). Means are provided for selecting the gear ratio set in the powershift transmission (34) from the excavator cab (32). Hydraulic motor (44) drives a pump (68) which provides pressurized automatic transmission fluid for lubricating the powershift transmission (34) and provides power for operating selected clutches in the powershift transmission (34). An accumulator (66) provides pressurized hydraulic fluid when remote driving of the vehicle (10 ) is initiated for smooth engagement of the selected clutches in transmission (34).
