<p>An excavator, backhoe, front loader or the like is converted for breaking reinforced concrete and other materials by removing the bucket, fitting an auxiliary mounting point (72,110) under the articulated excavator arm (44) about twice as far from the crowd link (54,80) as the bucket mounting point (50) is from the crowd link, and fitting a first jaw member (76,106) thereto. A second opposed jaw member (78,108) is added, braced by a stay bar (82,126) or a hydraulic cylinder (136), to form jaws with about twice the power of jaws mounted conventionally at the bucket mounting point, using the standard actuator (52), crowd link (54) and stabiliser link (56) of the excavator. <IMAGE></p> |
