Abstract
A rotating hammer-shear for releasable attachment to the boom structure and hydraulic system of a hydraulic excavator for the demolition of concrete structures. The hammer-shear having a heavy duty power operated shear and hammer secured to and extending from opposite ends of a common frame. The frame includes a rotational mounting. The rotational mounting provides for rotation of the hammer-shear through an arc of 360.degree. about an axis essentially perpendicular to the line of longitudinal extension of the shear and hammer from the frame. The rotational mounting also provides for pivotal attachment of the hammer-shear to the boom structure and hydraulic system of the excavator.
