Abstract

There is a permanently connected and protected extendable hydraulic feed pipe to the drill. The pipe is protected by siting it on the upper face of the rib arm and has an extension reserve loop and a guide pulley, with an elastic lanyard maintaining the pipe in tension over the pulley. In a rest position the drill locates, against the lower face of the jib. The pipe to drill connection locates on the drill face remote from the bucket and the drill is on a forked arm which rotates about a hinge on an axial drill extension.
