SIDE BRACKET FOR HYDRAULIC BREAKER AND HYDRAULIC BREAKER HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a side bracket of a hydraulic breaker which enables the hydraulic breaker to be put on a forwarding attitude where the total height of a topmost section of a boom of a work machine is reduced without removing a rod from a hydraulic breaker body.SOLUTION: In a layout of two pin holes 221 and 223 of a side bracket mounting section 220, at the time of a storage attitude K where a hydraulic breaker 200 is held on an arm side of a work machine 100, an angle α formed by a center O1 of the arm pin hole 221 and a line CL3 connecting a center O2 of the link pin hole 223 and a rod axis line CL1 of a hydraulic breaker body 201 is set at 45° or less so that a rod axis line C1 is parallel to an axis line CL2 of a bucket cylinder 106 provided along an arm 102 of the work machine 100 or a rod head side becomes narrow.SELECTED DRAWING: Figure 3
