Use:These chains are mainly used in industrial scenarios such as lifting, traction, and
transmission.
1.Lifting and Hoisting Scen
In lifting machinery (such as cranes, gantry cranes, and hoists), chains serve as core load-
bearing components, hanging and connecting to lift, move and position heavy objects.
Their high-strength characteristics can withstand large loads, ensuring the safety and
stability of lifting operations.
2.Transmission and Power Transmission Scarios
In mechanical equipment (such as conveyors, elevators, and agricultural machinery), chains
act as transmission components, transmitting power from the driving wheel to the driven
wheel to the equipment. These chains need to have wear resistance and fatigue resistance
to meet the needs of long-term continuous operation.
3.Traction and Tugging
ScenariosIn logistics, mines, ports, and other scenarios, chains are used to pull heavy
objects (such as cargo, mine carts, and containers) for movement. Their ring structure and-
strength design can withstand the tension during towing, meeting the traction
requirements under complex working conditions.
4.Other Industrial Application Extensions
Some chains are also used in machinery (such as conveyor chains), agricultural machinery
(such as tractor drive chains), and other subdivided fields, relying on the wear resistance
and corrosion resistance characteristics of material (such as manganese steel) to adapt to
the special working conditions of the industry.
