CLIMBING STEP DEVICE FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a climbing step device having a structure capable of preventing the breakage of bolts due to collision of a rock or the like and thereby preventing the coming off of the step when a structure fixing the step by the bolts is employed in a construction machine such as a hydraulic shovel.;SOLUTION: A pair of blocks 5 for mounting a step are welded to the outside surface of a side frame 1a of a traveling body. Step mounting grooves 7 with their upper surfaces opened are formed between the blocks 5 and the side frame 1a. Mounting pieces 6b formed on both ends of the step 6 are fitted into the step mounting grooves 7 from the upper side. The mounting pieces 6b are fixed to the side frame 1a by the bolts 9. The structure is so formed that the heads 9a of the bolts 9 are not projected outside from the blocks 5. The bolts 9 are protected by the blocks 5.;COPYRIGHT: (C)2001,JPO
