Some Knowledge about Stage Hoist

Stage chain electric hoist is a kind of lifting equipment designed for stage, performance and other places. It is often used to hoist heavy objects such as lighting, audio equipment, stage props, etc. Its precise control, high stability and flexibility make it one of the indispensable equipment for modern stage performances. So, what is the working principle of stage chain electric hoist? This article will analyze its structure, working process and control system in detail.

1. Basic structure of stage chain electric hoist

The main components of stage hoist include:

Motor: Provides power, usually driven by electric motor, and drives the mechanical device inside the hoist by rotation.

Drum and chain: The motor drives the drum to rotate, so that the chain moves up and down, so as to hoist objects.

Gear transmission system: Controls the lifting and lowering of the chain to ensure smooth and precise movement.

Braking system: Prevents the load from sliding down when it stops, ensuring safety. Generally equipped with an electric brake system, which can quickly lock the hoist position when the motor stops.

Control system: Including manual control, remote control or automatic control system, allowing operators to achieve precise control in different ways.

2. The key role of the control system

The working principle of the stage hoist is inseparable from the accuracy of its control system. According to different needs, the control system of the stage hoist can be divided into many types:

Manual control: operated by manual buttons or pull ropes, suitable for simple operating environments, convenient and fast.

Remote control: operated using a wireless remote control, suitable for occasions that require a certain distance of operation, such as the need to remotely adjust the lifting height of the equipment during a performance.

Automatic control: The stage hoist integrating modern technology may be equipped with an intelligent control system, which can automatically complete the lifting operation according to the set program to ensure more accurate lifting.

3. Accuracy and safety of stage hoists

The precise control of the stage hoist is one of its major features. Due to the complex stage environment, the position of the object hoisting requires extremely high accuracy. To ensure this, modern stage hoists are usually equipped with high-precision sensors and encoders (we produce this type, and there are also ordinary ones), which monitor the load and position changes in real time, and feedback information to the control system to ensure the accuracy of the operation.

In terms of safety, stage hoists are usually equipped with multiple protection measures:

Overload protection: When the load exceeds the rated load capacity of the equipment, the system will automatically stop working to prevent equipment damage or safety accidents.

Emergency stop function: In the event of a fault or emergency, the operator can immediately stop the equipment through the control system.

Safety locking device: Prevent the load from accidentally sliding down when the equipment stops, ensuring the safety of operation.

4. Summary

As a professional lifting equipment, the working principle of the stage hoist integrates mechanical, electrical and control technologies. Through motor drive, chain, wire rope transmission and high-precision control system, the stage hoist can complete precise load lifting, ensuring the safe, stable and efficient lifting of equipment and props in the stage environment. At the same time, with the continuous development of intelligent technology, the working principle and control system of the stage hoist will become more efficient and safer in the future.
