material and structure
Material: lifting chain is usually made of high strength alloy steel, which has excellent tensile strength and wear resistance.
Structure: The chain consists of several chain rings, each chain ring is connected with each other to form a connected ring structure.
working principle
Connection and fixation: one end of the chain is fixed on the reel or sprocket of the lifting equipment (such as crane, hoist), and the other end is connected to the load through the hook or other devices.
Power transmission: lifting equipment through the motor or manual operation to drive the sprocket or drum rotation, driving the chain to move.
Lifting and lowering: when the sprocket wheel or reel rotates clockwise, the chain is rolled up and the load is lifted; when it rotates counterclockwise, the chain is released and the load is lowered.
safety mechanism
Limit device: prevent the chain from over winding or releasing to avoid equipment damage or accidents.
Overload protection: when the load exceeds the rated weight, the equipment stops automatically to prevent the chain from breaking.
application scene
Industrial field: widely used in factories, warehouses, construction sites and other occasions for lifting and carrying heavy objects.
Ship and harbor: used for loading and unloading cargo and equipment lifting operations.
maintenance and inspection
Regular inspection: the chain needs to be checked regularly for wear, deformation and cracks to make sure it is in good condition.
Lubrication and maintenance: regular lubrication to reduce friction and wear and prolong service life.
summarize
Lifting chain realizes the lifting and moving of heavy loads through high-strength materials and chain ring structure, combined with the power transmission of lifting equipment. Its safety mechanism and regular maintenance ensure the safety and reliability of operation.
