Abstract
A concrete or masonry breaker for mounting on a hydraulically operated shovel, for example, in which a pair of jaws pivoted one on the other is operated in pincer fashion by a hydraulic ram, one of the jaws having a long limb along which the ram is disposed to operate the jaws. The long limb provides a long mounting base for the breaker so that high bending moments can more easily be applied to the concrete to break it. A combined forward and backward acting embodiment is described.
