Key Components and Working Principle of Electric Chain Hoist

As a common lifting equipment, electric chain hoist is widely used in industries such as industry, construction, logistics and entertainment. It has the characteristics of small size, light weight, easy operation and high safety. We have a high-quality electric chain hoist for sale that is perfect for your material handling needs.

Key Components

Motor: The motor is the core component of the electric chain hoist and is responsible for providing power to the hoist. Usually a three-phase conical rotor motor or a bypass magnetic circuit motor is used. After the motor is powered on, it generates a rotational torque through electromagnetic action to drive the hoist to lift and move.

Reducer: The reducer is connected between the motor and the chain. Its main function is to reduce the output speed of the motor and increase the output torque. This makes the hoist run more smoothly during the lifting process and improves safety.

Load-limiting clutch: The load-limiting clutch is a safety device. When the load-bearing capacity of the electric chain hoist reaches the rated value, the load-limiting clutch will automatically disconnect to prevent the chain from continuing to lift and lower, thereby protecting the hoist from overload damage.

Brake: The brake is installed at the tail end of the motor. Its main function is to brake quickly when the motor is powered off to prevent the hoist from falling rapidly due to gravity and ensure the safety of the hoist.

Limit switch: The limit switch is installed on the chain of the hoist. When the hoist reaches the set rise or fall limit, the limit switch will be triggered, automatically disconnecting the motor power supply, stopping the hoist from moving, and preventing the chain from over-stretching or contracting.

Chain: The chain is the main load-bearing component of the hoist. Through the circular movement of the chain, the hoist can be lifted and lowered and the heavy objects can be suspended.

Working Principle

Lifting principle: When the motor is powered on, the electromagnetic force on the motor shaft moves to the right along the axis, the brake is released, and the motor starts to run. The motor reduces the speed through the reducer and transmits the power to the chain. The chain circulates inside the electric trolley chain hoist to realize the lifting and lowering of the hoist.

Control principle: The electric trolley chain hoist usually adopts ground control. The operator controls the lifting, walking and other actions of the hoist through the control box, button box and other equipment.

The key components of the electric chain hoist and its working principle make it a safe, reliable and efficient lifting equipment, which is widely used in various occasions. Understanding its working principle will help to better use and maintain the electric chain hoist. Our electric chain hoist for sale is designed with advanced technology, ensuring durability and efficiency in various lifting operations.
