Abstract
Abstract A dump body vehicle module for connection to a tractor module to form a complete vehicle. The dump body module includes a horizontally disposed frame with wheels adjacent one end and a coupling portion adjacent the other end for connecting it to a tractor module. A dump body is pivotally mounted on the frame for movement between a carrying position and a dumping position and hydraulic actuators are provided to move the dump body between the two positions. A pair of leg members are pivotally mounted on the dump body for movement between three positions, one a leg storage position, another for supporting the module on the ground, and the third for supporting the dump body in an elevated position relative to the frame.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A dump body vehicle module for connection to a tractor module to form a complete vehicle, comprising a horizontally disposed frame, ground engaging wheels connected to said frame adjacent one end thereof, a coupling portion adjacent the other end of said frame adapted for detachable connection to a mating coupling portion on a tractor module, a dump body carried by said frame and pivotally connected thereto, double-acting hydraulic actuators connected between said dump body and said frame for moving said dump body pivotally between a carrying position and a raised position, and legs adapted to be positioned between said dump body and the ground for supporting one end of the module when it is not connected to a tractor module, the said hydraulic actuators supporting said frame from said dump body in the last mentioned condition.
