Abstract:

The present invention comprises a compact variable height, concrete truck having a concrete mixing barrel which may be positioned in a raised position for maximum load transportation and concrete mixing and pouring, and which may be positioned in a lowered position for reduced load tranportation and concrete mixing and pouring and for low clearance truck storage. The raising and lowering of the barrel is performed by an elevation device mounted at the rear of the truck which causes the barrel to be pivoted in a vertical plane about a pivot point at the lower end of the barrel. Lock apparatus are provided for supporting the barrel in both a raised and a lowered position.
