In practical application, the drive mode of
the handrail is divided into two driving modes according to the number of
friction wheels: large friction wheel drive and small friction wheel set linear
drive. At present, most companies use large friction wheel drive, and only few of
companies use small friction wheel set linear drive, mainly some Japanese
companies.
The comparison diagram of various driving
modes as follows:
