Background Introduction
Some old escalators use short pitch roller chain step chains. These escalators are usually used in commercial and public transport occasions,like shopping mall, office buildings, hospitals, exhibition centers, hotels and airports, metro, etc. Therefore, there are strict requirements on the quality and safety of step chain as step chain is the key component in the escalator. After perennial use, if the step chain has worn out and reached its design service life, it must be replaced timely and propertly.
Product Detail
step chain pitch P = 67.73mm, 6P = step distance = 406.4mm.
The chain is connected to its left and right side link by solid axles. This design structure of left, right side link and solid axles is detachable. Normally, the solid axles are reserved for use. the single - strip link of step chain purchasing independently, and it is not include long axles, which are specified to define escalator width type of 1000, 800 or 600.
The step fixing with step chain is to use clamp bush and the step chain is used oil for lubrication.

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.
