Detachable H68.4 Escalator Step Chain CNAS Escalator Step Chain Roller

Background Introduction
Some older escalators are used short pitch roller chain of step chain. These escalators are usually used for commercial and public transport occasions such as office buildings, shopping malls, exhibition centres, department store, hospitals, hotels and airports, subways, train station, etc. Therefore, as the step chain is a key part of the escalator, there are strict requirements on the quality and safety of the step chain. After prolonged use, if the step chain has worn out and reached its designed service life, it must be replaced promptly and reliably.

 
Product Specification

 
Product Detail
 
Step Chain pitch P = 68.4mm, 6P = step distance = 410.4mm and the step chain is used oil for lubricated.

The chain is connected to its left and right side link by hollow axles. Normally, the solid axles are reserved and continue use, when change left and right side link chain. The left and right side link chain are same for type 1000, 800 or 600 escalator.
 he single-strip links of the step chain are purchased independently and do not include the long axles, which are specified by contract of escalator type 1000, 800 or 600 width if required.
 The step fixing design is to use the plastic clamping bushing.

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.
