Product Details

To check whether the stage electric hoist and the lifting sling are matched, you can start from the following aspects: Rated Load - **Compare Values**: Check the rated lifting capacity of the electric hoist, which is usually marked on the nameplate or in the instruction manual of the equipment. At the same time, confirm the rated load of the lifting sling, which is generally clearly stated on the label of the lifting sling or in the product information. Ensure that the rated load of the lifting sling is not lower than the rated lifting capacity of the electric hoist to ensure that the lifting sling can bear the corresponding weight during the lifting process. For example, if the rated lifting capacity of the electric hoist is 5 tons, the rated load of the lifting sling should be at least 5 tons. - **Consider the Dynamic Load Factor**: In actual stage use, dynamic loads may occur due to situations such as acceleration, deceleration, and shaking. It is generally recommended that when choosing a lifting sling, a certain dynamic load factor should be considered for its rated load. Usually, the dynamic load factor is between 1.2 - 1.5. That is to say, if the rated lifting capacity of the electric hoist is 5 tons, considering a dynamic load factor of 1.2, a lifting sling with a rated load of at least 6 tons should be selected. Dimensions and Specifications - **Loop Size of the Lifting Sling and the Hook**: Check whether the loop size of the lifting sling can cooperate well with the hook of the electric hoist. The loop of the lifting sling should be able to fully fit onto the hook, and the opening size of the hook should be large enough to ensure that the loop has a certain amount of movement space inside the hook, but not too large to cause the loop to easily slip out of the hook. - **Lifting Point of the Electric Hoist and the Length of the Lifting Sling**: Determine the installation position of the electric hoist and the height of the lifting point according to the layout of the stage and the actual lifting requirements. Then, measure the lifting height required from the lifting point to the object to be lifted, and select a lifting sling of an appropriate length. Ensure that after connecting the electric hoist and the object to be lifted, the lifting sling can not only meet the lifting height requirements but also not be too long to cause problems such as dragging on the ground or entanglement during the lifting process. Working Environment and Performance - **Speed Matching**: Stage electric hoists usually have different lifting speeds, which need to be selected according to the rhythm of the stage performance and actual requirements. The lifting sling should be able to adapt to the lifting and lowering speeds of the electric hoist, and no safety problems or negative impacts on the performance effect should occur due to too fast or too slow speeds. - **Environmental Adaptability**: If there are special conditions such as high temperature, humidity, or chemical corrosion in the stage environment, check whether both the electric hoist and the lifting sling can adapt to such an environment. For example, in a humid environment, the electric hoist should have good waterproof performance, and the lifting sling should be made of materials with moisture - proof and mildew - proof properties; in an environment with a risk of chemical corrosion, corrosion - resistant electric hoists and lifting slings should be selected. - **Safety Performance Matching**: Electric hoists generally have safety devices such as limit protection and overload protection. Check whether the setting values of these safety devices match the performance of the lifting sling. For example, the trigger value of the overload protection device should be within the safe bearing range of the lifting sling to avoid a situation where the weight allowed to be lifted by the electric hoist exceeds the bearing capacity of the lifting sling. Connection Methods and Compatibility - **Inspection of Connection Fittings**: Check whether the connection methods of connection fittings such as the hook and lifting ring of the electric hoist match those of the lifting sling. For example, some lifting slings are connected to the hook of the electric hoist through metal snap rings. Ensure that the size and strength of the snap rings are suitable for the hook, and the connection is firm and reliable, without loosening or unhooking during the lifting process.

- **Compatibility Test**: Before formal use, some simple compatibility tests can be carried out. Connect the lifting sling and the electric hoist, and perform no - load and light - load lifting and lowering operations. Observe the cooperation between the lifting sling and the electric hoist, such as whether there are problems like jamming, excessive shaking, or abnormalities at the connection parts.
