Full analysis of the usage process of stage electric hoist

　　1、 Preparation before use

　　(1) Check the equipment

　　Before using the stage electric hoist, it is necessary to conduct a comprehensive inspection of the equipment. The inspection includes checking whether the appearance of the electric hoist is damaged, whether the chain is deformed, and whether the hook has cracks. At the same time, it is necessary to check whether the electrical system of the electric hoist is normal, such as whether the power cord is damaged, whether the plug is loose, etc.

　　(2) Choose the appropriate installation location

　　Choose a suitable installation location according to the needs of the stage performance. The installation location should have sufficient strength and stability to withstand the weight of the electric hoist and the lifted object. At the same time, the convenience and safety of operating the electric hoist should also be considered, avoiding installation in places that may affect the performance of actors or the audience's line of sight.

　　(3) Install electric hoist

　　Install the electric hoist at the selected location. During the installation process, it is necessary to strictly follow the requirements of the equipment manual to ensure a firm and reliable installation. At the same time, it is also important to pay attention to whether the chain direction of the electric hoist is correct, in order to avoid situations where the chain is twisted or tangled.

　　2、 Operation process

　　(1) Connect the power supply

　　Insert the power cord of the electric hoist into the power socket and turn on the power. 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, it is necessary to check whether the power cord is firmly connected to avoid poor contact.

　　(2) No load trial operation

　　Before officially using the electric hoist, a no-load test run should be conducted. The purpose of no-load trial operation is to check whether the operation of the electric hoist is normal, such as whether the transmission of the chain is smooth, whether the operation of the motor is stable, etc. During the no-load trial operation, attention should be paid to observing the operating status of the electric hoist. If there is any abnormal situation, it should be stopped immediately and inspected and repaired.

　　(3) Lift heavy objects

　　After the no-load trial run is normal, heavy objects can be lifted. Hang the heavy object on the hook of the electric hoist, then press the up button, and the electric hoist will start lifting the heavy object. During the process of lifting heavy objects, attention should be paid to controlling the lifting speed to avoid being too fast or too slow. At the same time, attention should be paid to observing the lifting of heavy objects. If there are any abnormal situations, the lifting should be stopped immediately and inspected and repaired.

　　(4) Moving heavy objects

　　After lifting the heavy object to the designated position, it can be moved to the desired position by operating the walking mechanism of the electric hoist. During the process of moving heavy objects, it is important to control the movement speed and avoid being too fast or too slow. At the same time, attention should be paid to observing the movement of heavy objects. If there are any abnormal situations, the movement should be stopped immediately and inspected and repaired.

　　(5) Lowering heavy objects

　　After completing the movement of the heavy object, you can press the descent button to lower it to the ground. During the process of lowering heavy objects, it is important to control the descent speed and avoid being too fast or too slow. At the same time, attention should be paid to observing the descent of heavy objects. If there are any abnormal situations, the descent should be stopped immediately and inspected and repaired.
