Background Introduction
Roller outside link pallet chain are widely used in Public and
heavy duty public moving walks. This type of moving walk are mostly
used in airport, metro, public transportation hub, etc place. Due
to intensive passenger flow, there are strict required of product
quality and safety. Pallet chain as one of driving system element,
it is the critical component in moving walk. 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, 3P = step distance = 406.4mm, Pallet
chain is used grease for lubrication.
The pallet chain is connected to its left and right side link by
solid axles. The solid axles of pallet chain are fixed with chain
link plate for transportation. The pallet chain has type 800, 1000,
1200 and1400 of product width.
The pallets are fixing with pallet chain axles through plain
bearing bush and sliding block
The pallet chain rollers are made by hydrolytic resistant
polyurethane. The chain roller hub is used polyamide 66. All
rollers have passed eligibility tests 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 pallet 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.
