Before using the vertical steel plate lifting clamp, in order to ensure the orderly operation of the follow-up work, we must first avoid the lock lever or the spring hook to contact the steel when determining the position of the steel plate clamp, whether it is on the roll or the roll down process. Cables, chains, rings and hangings.
Next, pay attention to check and confirm that the installation position of the vertical plate lifting clamp is appropriate and higher than the center of gravity of the hanging object.
Also make sure that the locking device (spring hook or lever type) is in a good locked state and the steel plate clamp is fully inserted. As a user, we need to determine the location of the installation in conjunction with the state of the landing. In particular, it is very dangerous when the landing object with poor stability when landing.
After a period of use, if the vertical plate lifting clamp is found to have the following problems, it should be scrapped:
1. The link is broken.
2, there are obvious cracks, cuts, dents, corrosion problems.
3, vertical plate lifting clamp chain ring, ring, middle or connection ring deformation.
4. The average diameter of the link is reduced by one tenth.
5. The nameplate is missing or illegible.
6. The chain stretches more than 3% at any location (outer dimensions of the link).
7. The hook widens by more than one-tenth.
