COUNTERWEIGHT SUPPORTING STRUCTURE FOR CONSTRUCTION MACHINE
PROBLEM : To improve the precision of position of a fastener hole and a seating face for mounting a counterweight provided at a counterweight supporting member when the counterweight is mounted to the counterweight supporting member through a fastener bolt. SOLUTION : A counterweight supporting member (16) is comprised of a supporting plate (17) erected and fixed at the rear end of a revolving frame (9) and a supporting member (18) attached to the supporting plate (17) that is fixed to the revolving frame (9), and the supporting member (18) is comprised of a base member (20) that is locked and secured to a through hole (17a) opened on the supporting plate (17) in a back and forth adjustable manner and has a counterweight fixing surface (20a) and a bolt fastening member (21) in which a fastener hole (21a) to be fastened by a fastener bolt (15) is formed.
La présente invention vise à améliorer la précision de position d'un trou de fixation et d'une face d'assise pour monter un contrepoids situé au niveau d'un élément de support de contrepoids lorsque le contrepoids est monté sur l'élément de support de contrepoids par l'intermédiaire d'un boulon de fixation. À cet effet, l'invention concerne un élément de support de contrepoids (16) qui est constitué d'une plaque de support (17) dressée et fixée au niveau de l'extrémité arrière d'un cadre rotatif (9), et d'un élément de support (18) fixé à la plaque de support (17) qui est fixée sur le cadre rotatif (9), et l'élément de support (18) est constitué d'un élément de base (20) qui est verrouillé et fixé à un trou traversant (17a) ouvert sur la plaque de support (17) d'une manière réglable en va-et-vient et comporte une surface de fixation de contrepoids (20a) et un élément de fixation de boulon (21) dans lequel est formé un trou de fixation (21a) qui doit être fixé par un boulon de fixation (15).
