Title:
CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP3245709
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To mount counter weight which is small-sized and has large specific gravity by forming projecting parts projecting to the outside of a car body direction on beams and forming beam fitting grooves extended to the outside of the car body width direction on counter weight.
SOLUTION: Beam fitting grooves 17a, 17a of counter weight 17 are formed into shapes extended to the outside of a car body width direction of storing recessed parts 17b, 17b. As a result, a fulcrum receiving load of the beam fitting grooves 17a, 17a mounted on a part on which the projecting parts 16a, 16a of the beams 16, 16 are formed is extended to the outside of a car body width direction and action force on the beam fitting grooves 17a, 17a is reduced. An anxiety in strength of a part connecting the beam fitting grooves 17a, 17a to be minimum cross section parts and the storing recessed parts 17b, 17b is eliminated. Therefore, counter weight which is small-sized and has large specific gravity such as weight having a molding structure can be mounted and the dimension of the rear part of the car body can be reduced.
