Abstract
A mobile loading machine having a frame and an operator's cab mounted thereon has a load arm assembly adapted to be pivotably mounted at a rear end of the frame, and support a power tool between a lowered position and a raised position at a forward end thereof. The load arm assembly includes an outer load arm section for supporting the tool, an inner load arm section pivotably mounted to the frame independent of the cab, and an intermediate load arm section integrally connected between the outer and inner load arm sections. The intermediate load arm section and inner load arm section are in overlapping relationship with each other such that the intermediate load arm section is positioned alongside a lowermost portion of the cab when the load arm assembly is in the lowered position to maximize the lateral visibility of the operator from the cab. The load arm assembly is a channel construction having a top wall and a bottom wall connected by a pair of sidewalls and the load arm assembly supports a supply line arrangement running along the load arm assembly to the power tool. A retaining device is positioned on the bottom wall between the extended portions of the sidewalls for protecting and concealing the supply line arrangement. A hydraulic cylinder arrangement is connected to the load arm assembly for moving the load arm assembly between the extended position and the retracted position. A safety bar is located adjacent the underside of the load arm assembly. The safety bar is retained in an inoperative position between the extended portions of the sidewalls and is movable to an operative position for holding the hydraulic cylinder arrangement in the extended position and preventing lowering of the load arm assembly.
