Vertical clamps are espcially designed for lifting (stainless) steel sheets, profiles or structures in a straight up direction. Terrier’s safety plate lifting clamps derive their name from the built-in safety mechanism, which consists of a locking device, a tension spring and a lever. Once the lever has been operated, the safety mechanism provides constant pre-tensioning of the cam on the steel-plate, thereby ensuring that the clamp does not slip when lifting force is applied. When a load is being lifted the clamping force on the cam is increased by the weight of the load.
The safety system also ensures that the clamp will not work itself loose from the plate as the load is being lowered.
