Summary: | PROBLEM TO BE SOLVED: To provide a low-speed operation device for a passenger conveyor having a simple structure capable of easily performing trial operation. SOLUTION: During trial operation, a low-speed operation motor 12 is mounted on a main frame, the low-speed operation motor 12 is connected to an input shaft 6 of a speed reducer 3 by a gear mechanism 15, and a worker artificially operates the low-speed operation motor 12 and drives the passenger conveyor at low speed. Manufacturing cost is reduced by the simple structure of the low-speed operation device attachably/detachably connecting the low-speed operation motor 12 to a driving machine 1. The speed reducer 3 is moved by the low-speed operation motor 12 and a tread chain is power driven at low speed. Human power operation at low speed thereby is unnecessary, energy in low-speed operation is saved, trial operation work time can be shortened, and work efficiency of the trial operation of the passenger conveyor is improved.
