The main components and mechanisms of electric chain hoists can be elaborated as follows:

Main components

Motor:

Type: Electric chain cranes usually use AC or DC motors as the driving force.

Function: When the electric motor is energized, electrical energy is converted into mechanical energy, which generates torque through the magnetic field interaction between the rotor and stator, thereby driving the lifting mechanism to lift and move.

Features: The speed and torque of the electric motor can be controlled by adjusting the power supply voltage and current, achieving precise control of the crane.

Chain:

Composition: A chain generally consists of links, chain plates, hooks, and locking components.

Function: The chain link connects the chain plate, which bears the load and transmits force. The hook is a fixed component of the chain, and the locking component prevents the chain from scattering and falling.

Lifting mechanism:

Composition: mainly including lifting mechanism and operating mechanism.

Function: The lifting mechanism controls the start stop and speed of the motor to achieve the lifting of the lifting mechanism and the lifting of goods; The operating mechanism controls the crane's movement on the track to complete the lateral movement of goods.

Control system:

Composition: Usually composed of controllers, travel limiters, cables, etc.

Function: Through the instructions of the controller, the motor works at different speeds and torques to complete various lifting, lifting or moving tasks.

Other components:

Including suspension rings, lifting ears, brackets, pull rods, pulleys, brakes, etc.

These components work together to ensure the normal operation and safety of the electric chain crane.

Working mechanism

Starting and lifting:

When the electric motor starts, the transmission mechanism drives the chain or rope for lifting and lowering movement.

The chain or rope interacts with the pulley group of the lifting mechanism to achieve the lifting of goods.

Horizontal movement:

Control the crane's movement on the track through the drive of an electric motor.

The operating mechanism consists of a large vehicle and a small vehicle, which achieve long-distance operation while the small vehicle controls lateral movement.

Precision control:

By controlling the instructions of the system, precise control of the motor speed and torque is achieved.

Operators can move the equipment horizontally and vertically through a joystick or button, controlling the direction and height of the lifting weight.

Security protection:

Equipped with safety devices such as travel limiters and overload protectors to ensure safety during operation.

Once an abnormal situation occurs, such as overloading or exceeding the limit position, the safety device will be immediately activated to prevent accidents from occurring.
