ABSTRACT A mobile scaler has a scaling head mounted to a carrier vehicle by an extensible boom assembly. The assembly has telescoping positioning and feed booms, the positioning boom being articulated to the vehicle for independent angular movement about a vertical axis and a horizontal axis, the positioning boom being articulated to the positioning boom for angular movement about the longitudinal axis of the positioning boom and a second orthogonal axis, and the tool head being articulated to the feed boom for movement about an axis orthogonal to the longitudinal axis of the feed boom. The tool head provides a combined prying and hammer function, and has a rock- engaging surface spaced from the tool to provide a fulcrum for prying forces. Hydraulic actuators controlling articulation and extension of the boom assembly have limiting valves to limit the transmission of stresses through the boom to the vehicle.
