Title:
REACTIVE FORCE SUPPORT STRUCTURE FOR SUPPORTING REPULSIVE FORCE GENERATED BY HYDRAULIC BREAKER HAMMERING, AND SMALL-SIZED HYDRAULIC HAMMER-TYPE BREAKING APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/070613
Kind Code:
A1
Abstract:
A small-sized hydraulic hammer-type breaking apparatus according to the present invention can stably support a repulsive force generated by hydraulic breaker hammering while having a small size and a small weight, and can be thus efficiently used in a building inner space, a small tunnel, a small mine, and the like. In addition, the small-sized hydraulic hammer-type breaking apparatus generally includes a hydraulic breaker, a bucket, and a conveyor, and can thus effectively perform a breaking operation in a narrow space.
