Detailed installation sequence of stage electric hoist

　　1、 Preparation work before installation

　　Determine installation location: Determine the installation location of the stage electric hoist based on the stage design and actual needs. The installation location should have sufficient strength and stability to withstand the weight of the electric hoist and the lifted object.

　　Check equipment and accessories: Before installation, carefully inspect whether the stage electric hoist and its accessories are complete and intact. Check whether the appearance of the electric hoist is damaged, and whether the chain, hook and other components are deformed or cracked. At the same time, check whether the required bolts, nuts, washers, and other accessories for installation are complete.

　　Prepare installation tools: Prepare the corresponding installation tools according to the installation needs, such as wrenches, screwdrivers, drills, etc.

　　2、 Install the electric hoist host

　　Fixed electric hoist host: Fix the electric hoist host in the installation position. Usually, bolts and nuts are used to fix the electric hoist host to structures such as trusses and steel beams on the stage. During the fixing process, it is important to ensure that the electric hoist host is securely installed without any looseness or shaking.

　　Connect power supply: Connect the power cord of the electric hoist to a power outlet. Before connecting the power supply, ensure that the voltage and frequency of the power supply match the rated voltage and frequency of the electric hoist. At the same time, check whether the power cord is damaged or short circuited to ensure safe and reliable power connection.

　　3、 Install chains and hooks

　　Install the chain: Thread the chain through the sprocket of the electric hoist host and connect the two ends of the chain together. When installing the chain, ensure that the winding direction of the chain is correct and there are no problems such as chain twisting or knotting.

　　Install the hook: Connect the hook to the end of the chain. When installing the hook, it is important to ensure that the hook is securely installed without any looseness or detachment issues. At the same time, it is necessary to check whether the opening size of the hook meets the requirements and can safely suspend the lifted heavy object.

　　4、 Debugging and testing

　　Debugging electric hoist: After installation, debug the electric hoist. Firstly, check whether the various components of the electric hoist are installed correctly and whether the chain and hook are securely connected. Then, start the electric hoist and check if its operation is normal, if the chain is smoothly wrapped around the sprocket, and if the hook can smoothly lift and lower heavy objects.

　　Perform load testing: After debugging is completed, perform load testing. Gradually increase the weight of the heavy object and observe the lifting capacity and stability of the electric hoist. During the load testing process, it is important to pay attention to safety and avoid overloading or sudden loading. At the same time, it is necessary to check whether the safety devices of the electric hoist are effective, such as limiters, brakes, etc.

　　5、 Inspection and maintenance after installation

　　Post installation inspection: After installation, conduct a comprehensive inspection of the stage electric hoist. Check if the installation of the electric hoist is secure and if all components are working properly. At the same time, it is necessary to check whether the operation of the electric hoist is smooth, and whether there are any abnormal noises or vibrations.

　　Regular maintenance: In order to ensure the normal operation and safe use of the stage electric hoist, it is necessary to regularly maintain the electric hoist. The maintenance includes cleaning various components of the electric hoist, checking the wear of the chain and hook, adding lubricating oil, etc. At the same time, it is necessary to regularly check whether the safety devices of the electric hoist are effective, and if any problems are found, they should be repaired or replaced in a timely manner.
