2) Installation of handrail system

Handrail system is subassembly with circular moving handrail, which is supported for

holding by passenger. Because of limit of transportation, subassemblies of handrail system are

not convenience to install on the escalator (except special). Handrail system assembling is

divided to two times to finished. in the first time, debugging、checking and remove to park are

finished in workshop, the second installation will be finished on building site, which is a

systemic engineering. See the appendix installation drawing.

Handrail system are composed of handrail driver、guide panel、handrail、handrail entry

device、skirt panel、inner and outer deck and top and bottom turning parts.

The handrail in the handrail system is a motional parts for holding by passenger, which

speed should be accordance with speed of step，and should be ahead of step for 0-2.0%,

Which can be done by adjusting handrail drivers.

Handrail driving system is a subassembly to drive handrail to move circularly (Figure

10-5).
