Handrail Drive Chains
A handrail drive chain is a system that allows you to quickly and easily change the direction of the railing in place. The system uses pressure roller assemblies to force the handrail 25 against the drive wheel 11. These sprockets make radial contact with the handrail, which ensures that the maximum force is transferred. They can be adjusted to increase or decrease the force they apply to the handrail.

Handrail Drive Chains Features
Drive chains are a vital part of escalators because they transmit motive force from the main axis of the escalator to the axis of the handrail. These chains are typically composed of two sets of chains with rollers spaced at regular intervals. Step chains also use several axels, which link the steps. The newel chain, on the other hand, has small bearings at the end of the newel to allow for smoother movement.
The installation process shortens the existing handrail 25 by approximately ten inches and replaces the frame 12 to fit the improved drive system 10 into a typical escalator system. The new frame 12 has an angle of about six degrees toward the top. The handrail drive system is thus compatible with an escalator with a six wheel roller drive system.
Types of Handrail Drive Chains
| There are several types of handrail chains, including Rollers 50, Handrail drive 18, and Self-measuring units. Listed below are some of the most common types: | |
| Handrail drive 18 | A handrail drive chain is a mechanical device that drives a handrail in a specified direction. The truss frame attaches the handrail using a pair of parallel guide bases. One guide base is located at the lower position of the truss and the other is located at the upper position. A truss drive chain includes a motor 19 that drives a sprocket 14a through a power transmission mechanism. The drive chains 18 attach another pair of sprockets via a chain guide system. |
| Rollers 50 | The self-tightening multiple nip mangle type handrail drive has two pairs of drive rollers. Each pair has a separate chain entangled in a common dual drive sprocket. An electric motor rotates these sprockets. Rollers 50 and 55 work in tandem with this type of drive, transmitting greater driving force without damaging the handrail. |
| R1 and R2 | The handrail drive chains that connect the Moving Handrail to the Trailing Rollers are the key to preventing a car from slipping and tumbling off the road. These chains come in R1, R2 and R3 configurations and are made to fit the respective railings. The R1 and R2 configurations are the most common, but variations in each level may exist depending on location and weather conditions. |
