Lightweight and compact, these lifting clamps, when used with fixed lifting beams, allow for quick adjustment of the clamp width, facilitating easy installation and disassembly and significantly improving lifting efficiency. 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: Luercher
