Grout delivery apparatus and method

摘要

A grout delivery apparatus and method for delivering grout through a flexible conduit from a bulk supply of grout to a hand tool. The bulk supply of grout is held in a hopper which feeds the grout under gravity to a pump. The pump is driven by an electric motor which receives its electrical energy through a controller. The controller is adjustably preset to control the electric motor as a function of the individual settings on a multifunction switch operable by the worker. The switch can either be mounted on the hand tool and directly wired to the controller or incorporated into a remote transmitter which transmits the particular switch position to a receiver on the controller.
