WORKING MACHINE FOR TRACK

摘要

PROBLEM TO BE SOLVED: To certainly brake a working machine for a track during towing by allowing using of a positive shaped brake even when a trouble occurs in an engine. SOLUTION: The working machine for the track has a track wheel for track running and a driving device for driving the track wheel in a lower running body of a machine body, and has a working device and an operation room in an upper turning body. The working machine has the positive shaped brake device for braking the track wheel. The positive shaped brake device comprises a manual hydraulic cylinder 41 that is disposed in the operation room and generates a braking pressure corresponding to the operation amount in an engine stopping state, and a running brake 23e that brakes the track wheel by receiving the braking pressure outputted from the hydraulic cylinder 41 and decelerates or stops the working machine for the track during running.
