Restricted area for the use of stage electric hoists

　　Stage electric hoist can help us quickly lift stage equipment and design some stage performances. However, before using it for homework, we also need to assess the environment of the homework site. Not all homework sites can meet the needs of using gourds. So, what are the prohibited areas for using stage gourds?

　　Firstly, when the power supply voltage is unstable or there is a risk of short circuit, we cannot use an electric hoist for operation to avoid circuit failure;

　　When we know the actual weight of the heavy object that needs to be lifted that we cannot remove, we cannot use a hoist for operation to avoid the danger of overloading;

　　When the working environment is quite harsh, such as high temperatures, rainy or snowy weather, or in highly corrosive environments, it can cause damage to the gourd and even lead to work accidents;

　　When we cannot firmly fix the gourd body, we cannot use it for operations.

　　The above are several situations where we cannot use stage electric hoists. If hoists are used in the above situations, there may be operational hazards. Everyone must pay attention when using them.

　　Why can't the stage electric hoist lift heavy objects

　　The stage electric hoist is a lifting tool that we often use when building stages and designing stage performances. We only need to fix it on the stage truss, connect the power supply, and press the switch. The stage hoist can help us lift the equipment we need to lift.

　　However, sometimes when we are doing homework, we may find that after pressing the switch, the stage hoist cannot lift heavy objects. Why is this?

　　When encountering such a situation, we first need to check whether the power supply is connected correctly and whether there is a short circuit in the wires;

　　Secondly, it is necessary to check whether the heavy object is overloaded, or whether it is fixed or connected to the ground;

　　When the chain becomes stuck, the hoist also finds it difficult to lift heavy objects;

　　When the motor malfunctions and the transmission system cannot rotate normally, the stage hoist cannot function properly.

　　When the stage electric hoist in our hands cannot lift heavy objects properly, we can check whether there is a malfunction in the hoist from the above aspects, promptly eliminate the fault, and maintain the stability and efficiency of the hoist to help us carry out stage construction operations.
