FRAME STRUCTURE OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide the frame structure of a working vehicle that can suppress vibration without adding any frame for reinforcement when a U-shaped frame is disposed in the working vehicle.

SOLUTION: A support frame 89 disposed in a hydraulic shovel includes a pair of L-shaped frames 92 and 93. The L-shaped frames 92 and 93 are prepared by dividing a U-shaped support frame into two by a connection part. The divided parts 92b and 93b are connected via a vibration suppression means 21 for suppressing vibrations of the divided parts 92b and 93b.
