There are significant differences in the mechanical principles between wire rope electric hoists and chain electric hoists. Although both devices are used for lifting and transporting heavy objects, they adopt different mechanical structures and transmission methods in the process of achieving this function.

Mechanical principle of wire rope electric hoist

The wire rope electric hoist is mainly driven by an electric motor to rotate the drum, thereby winding or lowering the wire rope wound on the drum, thus achieving the lifting and lowering of heavy objects. The mechanical principle mainly includes the following parts:

Electric motor: provides power source and drives the entire transmission system to work through the rotation of the motor shaft.

Reducer (some models may include): used to reduce the speed of the electric motor and increase torque, so that the drum can obtain the appropriate rotational speed and force.

Drum: Connected to an electric motor or reducer, it is the core component for winding and lowering steel wire ropes. When the drum rotates, the steel wire rope will be rolled up or lowered accordingly.

Wire rope: As a lifting medium, it bears the weight of heavy objects and transfers it to the drum. The strength and wear resistance of steel wire rope are crucial for the safety and reliability of electric hoists.

Control system: including electrical control components and limit switches, used to control the start, stop, and turn of the electric motor, as well as ensure that the electric hoist can automatically stop when it reaches the limit position.

The mechanical principle of chain electric hoist

Chain electric hoists use chains as the lifting medium and achieve the lifting and lowering of heavy objects through the meshing transmission of sprockets and chains. Its mechanical principles mainly include:

Electric motor: also serves as a power source, driving the sprocket to rotate.

Chain wheel: Connected to the electric motor, it is a key component of chain meshing transmission. There are multiple chain sockets on the sprocket to accommodate the chain and transmit power.

Chain: As a lifting medium, it bears the weight of heavy objects and lifts or lowers them through the meshing transmission of sprockets. The strength and wear resistance of the chain are equally important.

Control system: Similar to wire rope electric hoists, it is used to control the start, stop, and turn of the electric motor, as well as ensure that the electric hoist can automatically stop when it reaches its limit position.
