Document Type and Number:
Japanese Patent JPH0714790
Kind Code:
B2
Abstract:
Transportation apparatus for transporting passengers between spaced landings, including a conveyor, a conveyor drive unit, a handrail, a handrail drive unit, and a handrail drive pulley. The conveyor drive unit includes first and second spaced sprockets, and a drive chain reeved about the sprockets which drives the conveyor. The handrail drive pulley and a predetermined one of the sprockets are separately journaled for independent rotation about a common axis, with a drive belt linking the handrail drive pulley and predetermined rotational elements of the handrail drive unit. The pulley is selectively engageable with the predetermined one of the sprockets, to drive the handrail in synchronism with the conveyor when they are engaged, and enabling the frictional forces resisting the movement of the handrail to be directly measured when they are not engaged.
