摘要:
A method and apparatus for demolishing a structure is disclosed. A crusher member (12) is provided supported by a support frame (14). A reference position vertically above an operator is established. The relative distance between the crusher member (12) and the reference position in a generally vertical direction is monitored. The crusher member (12) is guided to the reference position as a function of the relative distance in order to prepare for a demolition cycle of removing a portion of the structure. The crusher member (12) is then manually manipulated through a demolition cycle.
