Abstract

A scissor frame lift for pivotally moving a dump body hingedly secured to a truck frame comprising upper and lower frame assemblies having the rearward ends thereof pivotally secured together and which are pivotally moved relative to one another by a hydraulic cylinder operatively interconnecting the upper and lower frame assemblies. The lower frame assembly includes a pair of elongated frame members, the forward ends of which are operatively pivotally or rotatably secured to mounts secured to the frame members of the truck frame. The upper frame assembly includes a pair of frame members, the forward ends of which are operatively connected to mounts secured to the runsills of the truck body. The distance between the rearward ends of the frame members of the lower frame assembly is substantially less than the distance between the frame members of the truck frame and is substantially less than the distance between the forward ends of the frame members of the lower frame assembly. The distance between the rearward ends of the frame members of the upper frame assembly is also considerably less than the distance between the forward ends of the frame members of the upper frame assembly. A unique body prop is also provided which prevents bending of the scissor frame during prop function.
