There are many differences between stage hand chain hoists and stage electric hoists in terms of power source, operation method, lifting speed, load - bearing capacity, application scenarios, etc. The following is a detailed introduction: 1. Power Source    - Hand Chain Hoist: It is driven by manual pulling of the chain. Through mechanical devices such as the hand chain wheel and brake, human power is converted into lifting or pulling force. There is no external power source, and it operates completely relying on the physical strength of the operator.    - Electric Hoist: It takes electricity as the power source. The motor converts electrical energy into mechanical energy, and then through components such as the reducer and drum, the lifting or movement of heavy objects is achieved. It needs to be connected to a power source to work. 2. Operation Method    - Hand Chain Hoist: During operation, the operator needs to manually pull the hand - operated chain. The lifting and stopping of the hoist are controlled by adjusting the speed and force of pulling the chain. The operation is relatively simple and straightforward, but the labor intensity is relatively high.    - Electric Hoist: It is usually operated by a push - button switch or a remote control. The operator can easily control the lifting, lowering, stopping and other actions of the electric hoist just by pressing the corresponding buttons or operating the remote control. The operation is more convenient and flexible, which can effectively reduce the labor intensity of the operator. 3. Lifting Speed    - Hand Chain Hoist: The lifting speed is relatively slow. Generally, the lifting height per minute is about 0.5 to 1.5 meters. The specific speed depends on the frequency and force of the operator pulling the chain.    - Electric Hoist: The lifting speed is relatively fast. Depending on different models and specifications, the lifting height per minute can range from 5 to 20 meters, which can greatly improve the adjustment efficiency of stage equipment and meet the needs of performances such as quick scene changes. 4. Load - Bearing Capacity    - Hand Chain Hoist: The load - bearing capacity is generally relatively small. The load - bearing capacity of common stage hand chain hoists usually ranges from 1 ton to 5 tons, which is suitable for lifting light - weight stage props, small - sized lighting equipment, etc.    - Electric Hoist: The load - bearing capacity is relatively large, ranging from 1 ton to dozens of tons, which can meet the needs of lifting and moving heavy - duty props, large - sized lighting racks and other equipment in large - scale stage performances. 5. Accuracy Control    - Hand Chain Hoist: Mainly relying on manual operation, it is relatively difficult to control the accuracy. It is difficult to achieve very precise positioning and fine - tuning, and may not be very suitable for some stage scenes with extremely high accuracy requirements.    - Electric Hoist: Equipped with advanced control systems and sensors, it can accurately control the lifting and lowering positions. The positioning accuracy can reach the millimeter level, which can meet the requirements for the precise positions of props and lighting equipment in stage performances. 6. Safety    - Hand Chain Hoist: Although the structure is simple, its safety depends to a certain extent on the skills and experience of the operator. If the operation is improper, such as the chain being pulled awry or overloaded, it may lead to safety accidents.    - Electric Hoist: Usually equipped with a variety of safety protection devices, such as overload protection, limit protection, broken - chain protection, etc., which can effectively prevent safety accidents caused by various abnormal situations, and the safety is relatively high. 7. Application Scenarios    - Hand Chain Hoist: It is suitable for some small - scale stage performances, community activity stages and other scenarios. These scenarios do not have particularly high requirements for the lifting speed, load - bearing capacity and accuracy of the equipment, and with limited budgets, the economy and simple operation of the hand chain hoist can give full play to their advantages.    - Electric Hoist: It is widely used in large - scale professional theaters, concert stages, TV studios and other scenarios with high requirements for stage effects. It can quickly and accurately complete the lifting and moving of various stage equipment, providing strong support for wonderful performances.
