Background Introduction
The commercial escalator and vast majority public escalator are used roller inside link step chain design. These kinds of escalator are mostly used in places with commercial building with nornal passenger flow or public transportation hub with light duty passenger flow, such as shopping mall, office buildings, hospital, train station, public transport building, transportation hubs and other places.
As the key driving component of the escalator, the step chain transfers power to transport passengers from one floor to the other through the step. Therefore, the safety and quality reliability of the parts must be guaranteed and strong required. After the escalator used many years, the step chain has worn out and exceeds the designed service life, it must be replaced on time and propertly to restore the product safety and reliability.

Product Detail
The step chain pitch (P) is 135.46mm; step pitch(step distance =3P) 406.4mm. This series step chain is used oil for lubrication.
The chain is connected to its left and right side link by hollow axles. This type step chain can be assembled with left and right side chain as whole chain for transportation or detachable for transporation as option.
The step chain width have 1000, 800 and 600 for escalator type.
There are two types of step fixing design: index pin bushing and the plastic clamping bushing.
The step chain rollers are made by hydrolytic resistant polyurethane and the step chain roller hub is used polyamide 66. The eligibility test of step chain roller include anti-hydrolysis 250 hours, oil hydrolysis 250 hours and life test running time 5000hours

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.
