ABSTRACT:
An improved vehicle includes a truck mounted material-handling mechanism having a main cab or operator's station from which the vehicle is driven over a road or highway and a second cab or operator's station from which the material-handling mechanism is operated. When the vehicle is being driven over the road, power is transmitted to the driving wheels of the vehicle from a main engine by a main drive line which includes a main transmission assembly. When the material handling mechanism is being operated, a control means in the second cab or operator's station is selectively operable to drive the vehicle with power transmitted from an auxiliary engine to the main transmission assembly in the main drive line by an auxiliary drive line. The auxiliary drive line includes a pump which is driven by the auxiliary engine to provide fluid under pressure to operate a fluid motor which is drivingly connected with the main transmission assembly.
