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.

Product Detail
Chain pitch P = 133.33mm, 3P = step distance = 400mm
step chain is used oil for lubrication.
The chain is connected to its left and right side link by hollow
axles. Normally, the hollow 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.
The single-strip links of the step chain are purchased
independently and do not include the long axles, which are
specified if required.
The step fixing design is to use the plastic clamping bushing.
The step chain rollers are made by hydrolytic resistant
polyurethane. The eligibility test of step chain roller include
anti-hydrolysis 250 hours, oil hydrolysis 250 hours and life test
running time 5000hours.

The step roller hub is used polyamide 66

Application
The pitch 133.33mm roller inside link step chain is used in widely
commercial escalator and a step distance of 400mm. It
is suitable for escalator product 9300, 9300AE, etc.
Producti and Quality Control
The step chain productio by Industry-Renowned step chain suppliers.
The entire step chain manufacture process includes meterial
imgress, component machining, part heat treatment and final
assembly with quality control plan to eansure each step chain
achieved original design requirement. The quality level is
consistent with international first-class brand escalator step
chain.
All type step chain achieved CNAS type test certificate.
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.
