Escalator Spare part, Roller Inside Link Step Chain - pitch 135.73, solid axles
Background Introduction
The commercial escalator are used roller inside link step chain design. These kinds of escalator products are mostly used in places with commercial building with nornal passenger flow such as department stores, shopping mall, office buildings, hospitals, exhibition centers, hotels and airports, etc. Therefore, there are strong requirements for the safety and production quality control, the step chain which is the critical component in the escalator drive system. After perennial use, if the step chain has worn out and reached its design service life, it must be replaced timely and propertly.

Our service
Our professional engineering team can provide technical support to help clients identify the appropriate step chain specifications to meet safety and lifetime requirements.
We kindly request our clients to provide us with any documents related to the escalator chain, e.g. technical service reports, spare parts numbers of the chain, drawings of the chain, breakage load certificates/breakage load calculations, etc. These documents can considerably speed up an inquiry and clarify discrepancies. To avoid any risk of providing a non-functioning chain, complete this questionnaire and an identification template with detailed photographs of the link plates, rollers, step pins, axles, axle parts and markings on the components. Please fill in the following points and chain templates as completely as possible. If the template deviates from the chain to be measured, sketch, measure and photograph the deviation in detail.
