One or more actuating valve assemblies control the flow of hydraulic fluid from the high pressure rail each of the actuation pistons.

Abstract: A hydraulically-actuated system includes a fix displacement variable delivery pump with a plurality of parallel disposed pistons that reciprocate in a pump housing the defines a high pressure portion and a low pressure area. A control device is attached to the pump housing and moveable between a first position in which the pistons displace fluid into the high pressure portion and a second position in which pistons spill fluid back to the low pressure area. The control device includes an electrically driven linear motion device, a linkage and a plurality of sleeves, one being disposed on each piston. Linear movement of the control device in turn causes linear movement of the sleeves. The position of the sleeves in turn determines the amount of output of the pump.

Abstract: The present invention provides a dump body having an improved skeletal structure reinforcing the body. The skeletal structure includes a plurality of longitudinal and vertical ribs. The ribs include at least one side leg and an exterior leg adjacent to the side leg. A cutout portion is defined in the exterior leg of the longitudinal legs.
