The working principle and operating steps of the stage electric hoist
Stage electric hoist is a type of electric hoist commonly used for stage construction, high-altitude equipment lifting, hanging display items, and so on. The working principle of the stage electric hoist is mainly based on the electric motor drive and mechanical transmission mechanism. The key steps in the operation of the stage electric hoist.
When the power is turned on, the motor begins to rotate, and the high-speed shaft of the reducer connected by an elastic coupling also rotates accordingly.
The driving torque of the electric motor is transmitted to the final stage large gear of the reducer through gears, and then connected to the hollow shaft through splines.
3. The hollow shaft is further connected to the drum through splines, causing the drum to rotate under the action of torque.
4. As the drum rotates, the steel wire rope begins to wrap or release, thereby achieving the lifting action of the hook and the lifted object.
To ensure the safety of operation, stage electric hoists are usually equipped with multiple protective measures such as limit switches and dual brake systems to prevent safety risks when the chain exceeds or becomes overweight.
When moving the suspended object to the designated position, the running car will walk along the lower edge of the I-shaped steel beam, driven by an electric motor to drive the wheels on both sides of the car. At the same time, the electromagnetic brake on the lifting mechanism will prevent the heavy object from falling and ensure smooth movement.
