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 pull ring design is ergonomic, crafted with superior casting techniques, resulting in high strength and toughness for stable and durable lifting. Multiple adjustable holes allow for customized opening sizes to accommodate various stone dimensions, greatly enhancing practicality and convenience. The stone lifting clamp is made of thickened alloy steel, forged at high temperatures, ensuring safety, durability, and resistance to breakage. It boasts excellent durability and stability, allowing for long-term use in harsh environments. The contact surface is made of polyurethane rubber, ensuring a firm grip on the stone without causing any damage. The textured rubber also increases friction, preventing stone slippage. Suitable for fragile or polished stone products. This lifting clamp is specifically designed for factory lifting, road construction, and stone transportation. Suitable for marble, granite, concrete slate, hollow bricks, rectangular bricks, etc., Manufacturer: WLH Alexanders
