Pictures for Otis Mitsubishi Kone Escalator Sidewalk Handrail Driving Chain Double Pitch

The design of escalator sidewalk double-row chain includes the choice of pitch, center distance, and the design of sprocket and chain. The pitch and center distance are selected according to the transmission ratio and calculation results. Sprocket selection Roller chain sprocket, the selection of its index circle diameter, tooth tip circle diameter, tooth root circle diameter, maximum tooth root distance and other dimensions are very important to the transmission stability and the life of the sprocket. Roller chain is a standard part, and its series and size are selected according to performance requirements and through national standards.

Escalator Drive Chain - FAQ

Q1: What is the difference between an escalator drive chain and a step chain?
An escalator drive chain transmits mechanical power between designated drive components, while a step chain connects and moves the escalator steps. Their designs, loading conditions, and replacement requirements differ.

Q2: Can escalator drive chains with the same pitch be interchangeable?
Not necessarily. Chains may differ in strand configuration, tensile strength, fatigue performance, roller geometry, materials, and sprocket compatibility.

Q3: What can cause excessive wear in an escalator drive chain?
Possible causes include abnormal loading, poor alignment, lubrication problems, sprocket wear, or unsuitable operating conditions. The chain and associated drive components should be inspected together.

Q4: What are common signs that an escalator drive chain needs inspection?
Excessive elongation, worn joints, damaged rollers, abnormal vibration, or unusual noise may indicate chain or sprocket deterioration.

Q5: What specifications are needed to source a replacement escalator drive chain?
Please provide the original chain model, pitch, strand configuration, roller and link dimensions, length or link count, sprocket information, and escalator model.
