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. The vertical clamp is a striking red, providing a clear contrast to other components and tools for easy identification. The vibrant color allows you to easily spot the clamp against any background in your workshop or warehouse. The contact surfaces for gripping stone are made of polyurethane rubber, offering impact resistance and wear resistance. The textured design ensures a secure, non-slip grip, enhancing safety and preventing damage to the stone during lifting operations. The lifting clamp is made of alloy steel with a rust-resistant coating, making it resistant to paint peeling and able to withstand harsh environments. It is safe, impact-resistant, durable, and has a long service life. The 7mm diameter manganese steel chain, equipped with a chain adjuster, allows for easy chain length adjustment. The opening size is freely adjustable to meet your needs for different sizes of stone. With powerful jaws, the vertical clamp can firmly grip steel plates of varying thicknesses. It is easy to operate, saving you time and effort. This heavy-duty clamp is used for vertical lifting and transportation; suitable for lifting concrete blocks, granite slabs, timber, steel plates, marble, bricks, and most types of materials or stone; allowing you to move materials safely and easily., Manufacturer: WLH Alexanders
