Lifting clamps utilize the lever principle, generating clamping force through the weight of the load itself, eliminating the need for an external power source. Operators can quickly lift and transport steel plates and structural steel sections with simple loading and unloading, significantly improving work efficiency and reducing manual labor intensity. This tool is not only ideal for gripping and moving heavy objects, but also embodies the utilization of gravity and the everyday application of physics. The polyurethane rubber material provides a strong grip without causing any damage or marks to the material surface. We provide two pairs of replacement anti-slip rubber pads (bright yellow), which can be replaced when the original anti-slip rubber pads wear out. This lifting clamp is ideal for repeatedly moving heavy objects. The robust chain is forged from manganese steel, and the steel plates are made of alloy steel. It is safe, durable, stable, and not easily broken. By adjusting the position of the pivot bolt on the clamp arm, materials of different thicknesses can be lifted. The chain length is also adjustable. The heavier the slab being lifted, the stronger the clamping force, securing it firmly. The vertical scissor clamp increases the clamping force with increasing tension and allows for a larger jaw opening, thereby improving lifting efficiency., Manufacturer: WLH Alexanders
