摘要：PROBLEM TO BE SOLVED: To solve a problem that a worker conventionally has to go up and down with a cargo on a stairway in case of carrying out maintenance work of an upper structure at a high place. SOLUTION: An electric winch 16 is mounted on a lower surface of the upper structure 13. It is possible to lift the cargo on the ground up to a working falsework 14 by using this electric winch 16. Consequently, it is possible to reduce fatigue of the worker and to improve efficiency of the maintenance work.
