Stage electric hoist: How to choose the appropriate suspension point

　　1、 Consider stage structure

　　The structure of the stage is the primary consideration when choosing suspension points. The structural strength and load-bearing capacity of different types of stages vary. For example, modern steel stages are usually able to withstand greater weight. When selecting suspension points, it is necessary to fully understand the structural design and load-bearing limitations of the stage, and avoid hanging electric hoists in areas with weak or easily damaged structures.

　　For steel stages, although their overall load-bearing capacity is strong, attention should also be paid to checking the structural integrity near welding points, support columns, and suspension points. Ensure that the area where the suspension point is located can withstand the total weight of the electric hoist and the lifted object.

　　2、 Evaluate the weight and distribution of heavy objects

　　Before selecting a suspension point, it is necessary to accurately assess the weight and distribution of the heavy object to be lifted. If the heavy object is heavy, it is necessary to choose a more sturdy and reliable suspension point. Meanwhile, the distribution of heavy objects can also affect the selection of suspension points. For example, if the heavy object is a large stage backdrop with an uneven center of gravity, the position of the suspension point should take into account the position of the center of gravity to ensure balance and stability during the lifting process.

　　For heavy objects, multiple suspension points can be considered to reduce the pressure on a single suspension point by dispersing the weight. When determining multiple suspension points, it is important to ensure that the distance and position between them can evenly distribute the force on the heavy object, avoiding situations where one suspension point is subjected to excessive pressure.

　　3、 Consider increasing height and angle

　　Elevating height and angle are also important factors in choosing suspension points. If it is necessary to lift heavy objects to a higher position, the height and position of the suspension point should be able to meet the working range of the electric hoist. At the same time, it is necessary to consider the angle changes during the lifting process to ensure that the suspension point will not collide with other objects due to the angle changes, such as electric hoists or heavy objects.

　　When selecting suspension points, the feasibility of different positions can be evaluated by simulating the lifting process. Consider the movement trajectory of heavy objects during the lifting process to avoid interference with other equipment, props, or personnel on the stage. If you need to lift at a specific angle, you can choose a suspension device with adjustable angles, or adjust the installation position of the electric hoist to achieve the desired angle.

　　4、 Ensure the firmness of the suspension points

　　Regardless of which suspension point is chosen, its firmness must be ensured. This includes checking the connection method of the suspension points, fixing devices, and surrounding structural supports. If the suspension point is on the stage truss, check the welding points, bolt connections, and overall stability of the truss. If it is on a wall or ceiling, ensure that the fixing device can withstand the tension of the electric hoist and heavy objects.

　　When installing suspension points, it is necessary to strictly follow the manufacturer's instructions and safety standards. Use high-quality fixing devices such as expansion bolts, hooks, etc., and ensure that they are installed and tightened correctly. Before use, some simple tests can be conducted, such as gently pulling the electric hoist to check if the suspension points are loose or shaking.

　　5、 Consider safety factors and emergency situations

　　Finally, when selecting suspension points, safety factors and handling of emergency situations should also be considered. Ensure there is sufficient space around the suspension point for quick rescue and handling in case of accidents. At the same time, it is necessary to understand the safety devices and emergency stop functions of the stage electric hoist to ensure timely stopping of lifting operations in emergency situations.

　　Clear warning signs can be set up near the hanging points to remind other personnel to pay attention to safety. If possible, emergency plans can be developed to clarify the response measures and division of responsibilities in case of unexpected situations.
