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. Utilizing high-quality manganese steel, polyurethane rubber, and a high-temperature forging process, the entire lifting clamp is made robust and wear-resistant. The superior materials, springs, and stable structure give this product high tensile strength, allowing the granite lifting clamp to easily lift various flat stones and significantly improve work efficiency. You can adjust the jaw opening range by adjusting the brake hole and securing it with the self-locking nut, easily handling stones of different sizes. The scissor design increases clamping force with increasing applied tension, and the single scissor action allows for a larger jaw opening. Therefore, you can move heavy objects more easily. The polyurethane rubber chuck features an anti-slip textured design, effectively preventing stone slabs from falling and damaging the stone, improving safety during use., Manufacturer: WLH Alexanders
