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. 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: Luercher
