PIPE DEVICE FOR CONSTRUCTION MACHINE AND STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a pipe device for a construction machine for preventing damage of a pipe without requiring a protective cover. SOLUTION: A freely traveling travel body 1 is composed of a center frame 1a and a side frame 1b fixed to both sides. Opening parts 1f and 1g are arranged on opposed surfaces of a connecting part of the center frame 1a and the side frame 1b. Since the pipe 13 is arranged in the side frame 1b via the inside of the opening parts 1f and 1g from the inside of the center frame 1a, the pipe 13 is not exposed outside the center frame 1a and the side frame 1b so that the pipe 13 can be surely prevented from being damaged by an obstacle such as rock at traveling and at work of the construction machine.
