摘要： PROBLEM TO BE SOLVED: To efficiently perform a moving handrail installation operation without applying a large labor burden to operators. SOLUTION: This handrail installation device 2 is formed so that, after it is installed on the upper side end part of a lower side curved part guide rail 66 by sucking it through a suction cup 21, an ear part 73 on one end side of a moving handrail 7 is hooked to a channel-shaped hook 24a of the installation device 2, the ear part 73 of the other end side is hooked to an L-shaped hook 23a, and a holder 26 is turned to move hold-in arms 23 and 24 relatively to each other in the direction that the hooks 23a and 24a are moved away from each other. Thereby, when the ear parts 73 on both sides are pulled by the hooks 23a and 24a and their distance is increased, the operation for engagement of the handrail installation device 2 with the moving handrail 2 is completed. When an operator holds the moving handrail 7 by the upper part of an intermediate part thereof and pulls downward, the moving handrail 7 invaded from the intermediate part into the handrail installation device 2 is pulled by the hooks 23a and 24a, and their distance is increased. Then these hooks are pushed into the lower curved part guide rail 66 by a push-in roller 22.

摘要： PROBLEM TO BE SOLVED: To shorten the working time on the spot greatly and secure reliability in quality when replacing the handrail of an escalator. SOLUTION: This connecting method is to sew canvas at both ends 50, 51 of a new handrail 40 not connected in an endless shape on a step 5 to make an endless shape. At this time, by sewing both ends 50, 51 facing each other by means of sewing machine 70 holding them horizontally on the step 5, the sewing efficiency can be higher than in hand sewing. Also by preparing a guide space for keeping sewed canvas from the canvas not sewed yet, the sewing work of both ends of the canvas can be performed smoothly. By completing the measurement and cutting of one end 50 of the new handrail 40 at the time of factory shipment, working time required for measurement and cutting on the spot can be shortened greatly and the improvement of precision in measurement can be attained.
