Background Introduction
The commercial escalator and vast majority public 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 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. 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 = 135mm, 3P = step distance = 405mm, step chain is
used oil for lubrication
The step chain is connected to its left and right sides by long
axles and the step chain have type1000, 800 and 600mm of escalator
width. The long axels are fixed with the chain link plate and are
not datachable for transportation. The steps are fixed with step
chain by clamp bush fastening.
The step-chain rollers are made of hydrolytic resistant
polyurethane. The eligibility test for step-chain roller
anti-hydrolysis is 250hrs, oil hydrolysis is 250hrs, and life test
run time is 5000hrs. The material of step chain roller hub is used
PA66

Application
The pitch 135mm roller inside link step chain is used in widely
commercial and public escalator and a step distance of 405mm. It is
suitable for velino series escalator.
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.
