AUXILIARY DEVICE FOR REPLACING BRIDGE SLEEPER AND METHOD FOR REPLACING BRIDGE SLEEPER

摘要

To provide an auxiliary device for replacing a bridge sleeper and a method for replacing the bridge sleeper capable of suitably performing the replacement work of the bridge sleeper.SOLUTION: When an auxiliary device 100 for replacing a bridge sleeper is used, a heavy bridge sleeper M can be suspended by an elevator 30 and easily moved, so that the burden of replacing the bridge sleeper M can be reduced. In particular, the auxiliary device 100 for replacing the bridge sleeper has a configuration in which one end 11 of a traveling girder 10 can be easily arranged above a side walkway W which becomes a work area; since the elevator 30 for suspending the bridge sleeper M can be moved to a position close to the side walkway W side, the work for removing or hanging the bridge sleeper M from a suspension part 33 of the elevator 30 can be suitably performed on the side walkway W.SELECTED DRAWING: Figure 1
