ABSTRACT:
An attachment for a loading bucket of a construction vehicle enables it to be used as a demolition device as well as a loading bucket. The attachment comprises a pair of elongated reinforcing members secured to the body of the bucket to form a rigid cross-sectionally square member on which spaced upstanding apertured plates are mounted so as to engage several surfaces of the reinforcing members. A demolition member consisting of a pair of jaws with a structural web therebetween is removably engaged on said upstanding apertured plates for pivotal movement between a first position in front of said loading bucket and a second position above said loading bucket. Piston and cylinder assemblies in said jaws engage the same and the upstanding apertured plates for moving said demolition member.
