Why does the stage electric hoist not lift heavy objects

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

　　However, sometimes when we are doing homework, we may find that after pressing the switch, the stage gourd 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 gets stuck, the gourd also finds it difficult to lift the heavy object;

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

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

　　Do not expose the stage electric hoist to direct sunlight

　　When we use stage electric hoists to build a stage outdoors, we often encounter sunny and scorching weather. The temperature in this weather is very high, and long-term work may cause heatstroke for the staff. The electric hoists are also very afraid of exposure to sunlight.

　　The stage electric hoist is used by connecting to a power source, and the high temperature generated by exposure to sunlight not only causes overheating of the power equipment, but also has an impact on the motor inside the hoist, which can seriously affect the hoist's crane;

　　Not only that, the working environment temperature under exposure to sunlight will be very high, which will have a certain impact on the metal components and chains inside the gourd. Long term exposure to sunlight can cause corrosion and deformation of the metal components of the gourd, which may accelerate the aging, wear and even scrap rate of the components.

　　In the scorching summer, while enjoying the cool air conditioning, don't forget to take a break for the electric gourd on stage to feel cool and avoid the negative impact of direct sunlight on the gourd.
