Standards

！This product is not for overhead lifting.

！Any surface coating will affect the mechanical properties of the chain.Please ask staff for details.

！Fatigue resistance T [cycles] and impact force KV [J] according to DIN 22258 standard

！Enhanced performance connecting link not recommended for use in harsh, corrosive environments, as pitting and friction martensite may lead to operational failures.

！Ensure the cleanliness of the mounting surface and locking surface.

！Regular inspection for wear and damage.

！It is not allowed to insert other accessories between the two chainrings.

！Inspection is conducted every three months or after 1 million tons of coal is transported.

！Insert the two half rings into the chain and buckle them together, and drive in the middle fixing pin to prevent them from loosening.
