All users should read our "Warnings" and "Design Safety Guidelines" before using our products.
Warnings
Fire
uni-chains plastic products are, unless clearly specified, made from materials which support open flame.
Products made from POM material (D, I, LF and SLF), when so exposed, will emit toxic fumes. uni-chains plastic
products should therefore not be exposed to extreme temperatures or open flame. Special care should be taken
when undertaking repair work particularly when welding at a conveyor if the conveyor is equipped with plastic
chains or belts.
Personal Protection
Always use safety glasses when installing or repairing chains and belts and while securing or removing pins.
Use only suitable tools in good condition.
The weight of some products calls for the use of safety shoes.
When installing/removing or repairing chains or belts on a conveyor, the motor must be turned off.
Design Safety Guidelines
Most plastic products will lose their mechanical properties if exposed to the sun or ultraviolet beams, which can
lead to chain or belt breakage. This can also happen if the products are exposed to strong chemicals. Generally,
this is a problem with pH values lower than 4.5 or higher than 9.
Always make sure that there is enough space in the conveyor frame to allow chains and belts to retract or expand
when exposed to temperature variations.
Never exceed the maximum or minimum temperatures given by uni-chains.
Note: The different materials have different temperature limits.
Care should be taken with high chain/belt speeds at which friction can lead to heating and subsequently melting of
chain/belt as well as wearstrips. Do not exceed speeds recommended by uni-chains.
Use only original uni-chains sprockets with uni-chains belts and chains.
When constructing conveyors it is important to always include sufficient cover around the moving parts to prevent
fingers and clothing from being caught in the machinery. uni-chains can also supply safety chains and side flexing
belts which leave minimal gaps when turning through curves making them safer than regular chains.
