Vertical lifting steel plate lifting pliers is a kind of lifting tool used for the vertical lifting of steel plate goods.
The clamping force between the clamps tongue and steel plate is an important factor affecting the safety of vertical lifting steel plate lifting pliers. If the clamping force between the clamps tongue and steel plate is too large, the steel plate will be damaged and the life of the clamps will be shortened. In serious cases, the stress of the clamps body or the clamps tongue will exceed the allowable stress, resulting in the fracture of lifting pliers.
If the clamping force between the crane tongs and the steel plate is not big or enough, the steel plate will slip and the above phenomena will occur.
