WORKING DEVICE FOR CONSTRUCTION EQUIPMENT

PROBLEM TO BE SOLVED: To provide a working vehicle for construction equipment, which can reduce the dimension, the weight, etc. of each link forming a parallel support member, by arranging the parallel support members on both right and left sides of a boom, to thereby achieve downsizing and weight reduction of the working device. SOLUTION: According to the structure of the working device, the parallel support member 23 is formed of a pair of the right and left rinks 27, 24 which are connected to a first boom 12 and a third boom 15. Thus even if the second boom 13 is rocked either in a right direction or in a left direction by an offset cylinder 20, one of the links 27, 24 pulls and rocks the third boom 15, and therefore the third boom 15, an arm 17, a bucket 18, etc. are moved rightward or leftward in a parallel manner. Therefore the links 27, 24 need not bear a force in a compressing direction, and therefore their cross sectional areas, their weights, etc. can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI
