Background Introduction
Roller inside link pallet chains are widely used in commercial and
public moving walks. This type of product are mostly used in
department store, shipping center, airport, public transportation
hub and metro, etc place. Due to intensive passenger flow, there
are strict required of product quality and safety. Pallet chain is
the key component in moving walk and also is one of driving system
element in the product which transfer power to drive pallet running
for transport the passenger. After perennial use, if the pallet
chains have worn out and reached its design service life, it must
be replaced timely and propertly.

Product Detail
Chain pitch P = 135.46mm, 2P = pallet distance = 270.92mm, Pallet
chain is used oil lubrication.
The pallet chains are connected to its left and right side link
chain by fixing with pallets through pins & bushs assembly. The
pallet chain is detachable design for transportation and the
replacement of pallet chain is for left & right side link
chain. The chains are the same for type 1000 and type 800 moving
walk.
The pallet chain rollers are made by hydrolytic resistant
polyurethane. The pallet rollers have passed eligibility tests
include anti-hydrolysis 250 hours, oil hydrolysis 250 hours and
life test running time 5000hours. And the pallet chain roller hub
is used polyamide 66.

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.
