Inspection and selection of plate lifting clamp

- Nov 06, 2018-

In order to ensure daily safe and reliable operation, when repairing the steel plate lifting clamp, first ensure that the jaw opening degree is increased by 10% within the original size. Steel plate clamps shall be marked with a safety load and the like. Secondly, it should be noted that the surface of the steel lifting clamp should be smooth and flat, and there should be no cracks or damage. The welding should be welded, free of slag inclusions and no welding deformation.


At the same time, in the maintenance work, it is necessary to confirm that the lifting ring, shaft hole and other parts of the steel plate lifting clamp are good, there is no crack, and the wear amount of the lifting ring does not exceed 10% of the original diameter. The steel plate clamp shall be tested with a double safety load for five minutes. After unloading, a full inspection shall be carried out without permanent deformation.


So in practical applications, do you know how to make full use of the function and function of the steel lifting clamp to make it a good application? First of all, we should choose the tongs that match the actual use, and use them within the allowable load range, and should not be overloaded. Also note that it must be used within the allowable plate thickness and must not enter the hoisting range or the flip area. The steel plate clamps shall not knock or impact the hanging objects and spreaders, nor shall the lifting objects move sharply or stop abruptly.
