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. Made with carefully selected high-quality hardware screws, these clamps are durable, non-slip, and ensure safe and convenient use. The special material won't damage stone, and the textured surface increases friction to prevent slippage. Our lifting clamps are available in two sizes: a large clamp (390kg, 8cm opening) and a small clamp (320kg, 5.5cm opening). Constructed from high-quality alloy steel and processed with a high-temperature forging process, these clamps are safe, reliable, and have a long service life. This vertical steel plate clamp is specifically designed for the vertical lifting and transport of steel plates and structures., Manufacturer: WLH Alexanders
