Product Details

In addition to the dual - brake system, there are various mechanical safety designs to improve the safety of stage electric hoists as follows: 1. **Multiple Safety Locking Mechanisms** - **Safety Pins**: Safety pins are installed at the key transmission parts or connection parts of the electric hoist. When the equipment stops running and is in a stationary state, the safety pins can be inserted to further fix the relevant components, preventing the components from moving or loosening due to accidental vibration, misoperation, etc., and playing an additional safety - locking role. - **Locking Washers**: Locking washers, such as spring washers and toothed washers, are used at bolt - connection parts. Through the special design of these washers, the friction and fastening force of the connection are increased, preventing the bolts from loosening during operation and ensuring the stability and reliability of the connection of various components. 2. **Wire Rope/Chain Protection Devices** - **Broken - chain/Broken - rope Protection**: Broken - chain or broken - rope protection devices are installed. When the wire rope or chain breaks, this device can quickly jam the moving parts of the electric hoist to prevent the heavy object from falling. Commonly, there are mechanical block - type and electromagnetic - induction - type broken - chain/broken - rope protection devices. - **Anti - skipping Device**: An anti - skipping device is set at the pulley or sprocket of the electric hoist to prevent the wire rope or chain from jumping out of the pulley or sprocket during operation, avoiding equipment damage and safety accidents caused by skipping. - **Wear Detection Device**: A wear - detection sensor for the wire rope or chain is set to monitor its wear condition in real - time. When the wear reaches a certain level, an alarm signal is sent to prompt the operator to replace it in time to ensure its load - bearing capacity and safety. 3. **Rigid Structure Design** - **High - strength Frame**: The frame structure of the electric hoist is made of high - strength metal materials, increasing its overall rigidity and stability. It can withstand greater external forces and impacts, and is not prone to deformation or damage when lifting heavy objects. - **Reinforcement Rib Design**: Reinforcement ribs are set at the key parts of the frame structure to improve the strength and anti - torsion performance of the structure, further enhancing the overall stability of the electric hoist and ensuring safe and reliable operation under various working conditions. 4. **Buffer Devices** - **Upper and Lower Limit Buffering**: Buffer devices such as rubber buffer blocks and spring buffers are set at the upper and lower limit positions of the electric hoist. When the hook reaches the limit position, the buffer device can absorb and buffer the impact force of the hook, reducing damage to the equipment and structure, and also reducing the safety risks caused by the impact. - **Running Buffer**: Buffer devices are set at both ends of the running track of the electric hoist to prevent the electric hoist from colliding with the end of the track due to excessive speed or untimely braking during operation, protecting the safety of the equipment and personnel. 5. **Anti - sway Devices** - **Guide Wheel Set**: A guide wheel set is set near the hook of the electric hoist or the suspension point of the heavy object. Through the guiding effect of the guide wheels on the wire rope or chain, the swing range of the heavy object during lifting and operation is limited, reducing the impact of sway on the equipment and the surrounding environment, and improving the stability and safety of lifting.

- **Damper**: A damper is installed to suppress the sway of the heavy object. The damper can consume the energy of sway through friction, hydraulic or electromagnetic means, making the heavy object stop swaying as soon as possible and reducing safety risks. Especially in large - scale stage performances, it can effectively prevent the sway of heavy objects from causing damage to stage facilities and actors.
