Abstract
(EN)

A working machine with a crawler includes a lower traveling body having a pair of crawlers, an upper turning body, an extension beam installed rotatably to be parallel in a longitudinal direction of the crawler, a fitting portion opened in a side frame of the crawler, a fixing pin fixing the extension beam to the side frame, a fixing pin insertion hole, a fixing pin fitting hole, and a reinforcement rib, in which the extension beam extends to be inserted into the fitting portion, and the reinforcement rib is provided at a center portion of an opening of the fitting portion, and the fixing pin fitting hole is disposed at a position which is deviated from an imaginary center line extending along a longitudinal direction of the fitting portion from the center portion and does not interfere with the reinforcement rib.
