Steel plate clamps are correctly installed and prevent hanging objects from falling

When it is necessary to determine the clamping position, the locking bar or the spring hook must be prevented from coming into contact with the cable, the chain, the lifting ring and the hanging material during the winding or unwinding process.

Confirm that the clamp is installed at a position higher than the center of gravity of the weight.

Check if the lock position (spring hook or lever type) is in a good lock state.

Confirm that the jaws are securely inserted.  

The state of the hanging object at the ground must be considered to determine the installation location. Especially the poor stability of the hanging when landing is quite dangerous.

We need to pay attention to the fact that steel plate hangers or spreaders fall are the most common types of lifting injuries.

 The occurrence of such accidents is mainly caused by improper fitting of steel plate clamps, poor maneuvering of drivers, improper selection of spreaders and rigging, lifting and overloading limiters. Therefore, it is necessary to strengthen the steel plate clamp accident prevention measures:  First of all, the promotion of the height limiter should be guaranteed to be effective and avoid over-creation accidents. The driver should check whether the lift limiter is valid before the homework, and should not be activated when it fails. Secondly, it is necessary to pay attention to the inspection of the steel plate tongs, whether there is wear or crack deformation, the scrap is not allowed to use; Third, to check the condition of the wire rope, it is necessary to check the wire rope from the beginning to the end before each shift, whether there is wear, broken wire, broken off, whether there is obvious deformation, kinking, bending, etc. Replace it in time.
