Abstract
A flowable concrete delivery apparatus is provided in which both rigid and flexible pipe is connected in an end-to-end relationship to provide a high pressure conduit. These lengths of pipe are connected by clamps, each clamp being fixedly secured to a skid that provides a sliding protector for the clamp and prevents unwanted opening and damage to the clamp. The pipe lengths are carried by freely rotating wheels, each having a sleeve that provides a free fit on the outer diameter of a pipe length. The conduit is moved by a hook tool, this tool having one end formed with a handle and the other end with a bifurcated hook that is contoured to releaseably engage the outer diameter of a pipe. An attendant manipulates and moves this hook tool to position and arrange the conduit pipe in the desired delivery position. Although a great convenience, the hook tool is not required by the attendant in every instance as the wheels enable the attendant to grasp and move the pipe conduit when the occasion arises.
