Escalator Drive Chain
The escalator drive chain is divided into two parts: the main drive chain and the handrail belt drive chain. Each of these parts has different characteristics, which can affect their performance and longevity. In addition to preventing premature wear and tear, they should be designed to align the sprockets and engine chains in the correct direction. In addition, escalator drive chains should be lubricated regularly to ensure maximum performance. This can be done manually or automatically.
An escalator’s drive unit consists of an electric motor, decelerator, electromagnetic brake, and V belt. These parts transmit power to the drive wheel, which in turn drives the Trailing Rollers. A drive chain drives the Moving Handrail. This chain transfers the motive force from the gearbox shaft to the main drive shaft. To prevent excessive wear and tear, an escalator must have a safety device that disconnects the main drive motor in case of emergency.

There are a few easy ways to keep the escalator drive chain in great condition. First, be sure to check the pitch of the drive chain. Many chains are too short to be effective for heavy loads. Fortunately, there are ways to adjust the pitch of the chain without causing damage to the escalator.

Pitch of Escalator Drive Chain
The pitch of an escalator drive chain is the ratio of the number of teeth to the step pitch. There are four or six teeth in a chain. This can affect the smooth running of the escalator. Large linear movements can affect the redirecting station and disrupt the smooth running of the escalator. If this happens, the escalator may not be safe for the users. Therefore, proper design is required to minimize the risks of accidents.
The pitch of the escalator drive chain should be as small as possible to lessen the effects of chordal action. Although the installation of an escalator step chain varies by country, the principle is the same. The bearing part of the chain plate is located at the center of the step shaft. The step shaft and extended pins support the weight of the steps and travelers. If the chain pitch is too large, the escalator may not run smoothly.
