Abstract

PROBLEM TO BE SOLVED: To provide a method and device for carrying an escalator footstep capable of easily detaching and attaching a footstep at the intermediate inclined part of an escalator. SOLUTION: An escalator step transportation device is installed movably on a moving handrail 5, and provided with a weight lifting means 15 which suspends a step 8a and an operating means 16 which moves the weight lifting means 15 along the moving handrail 5. After the step 8a is lifted with the weight lifting means 15 held on the moving handrail 5 at the intermediate inclined part, a windup jig 27 is operated so as to lower the weight lifting means 15 by self-weight to a lower access port 1 for the carrying out of the footstep 8a. Also the weight lifting means 15 which suspends the footstep 8a is raised from the lower access port 1 to the moving handrail 5 at the intermediate inclined part by winding up the take-up jig 27 for the carrying in of the footstep 8a. Thus, when a footstep for wheelchair, etc., is detached or attached, the working expenses can be reduced.
