ABSTRACT:
A ground supported excavating machine of the type having a main frame and a prime mover for propelling the machine along the ground, and a boom supported from the frame that has an endless chain type digging member rotated by sprockets on a head shaft that is mounted at one end of the boom, and on a tail wheel shaft mounted at the opposed end thereof, to provide a lower run that engages the lower surface of the boom. The interior of the boom is made into a liquid container that communicates with the bottom surface of the boom, which is filled with sufficient liquid to transfer heat from the relatively hot boom lower surface to a relatively cold boom surface. A wear plate assembly is mounted to the lower surface of the boom and covers the lower surface of the boom near the tail wheel sprockets, and isolates the upper surface of the wear plates from the lower surface of the boom by suspending the wear plates for loosely contacting the boom lower surface with very little force respective to the force with which the lower run engages the lower surface of the boom while digging.
