Enhanced Grip Technology: The vertical plate grippers employ a scissor mechanism that increases gripping force by creating added tension, allowing for a broader jaw opening and improving operational efficiency. Durable Alloy Steel Construction: Made from premium alloy steel through high-temperature forging and coated for rust resistance, these stone lifting pliers ensure exceptional safety, long-lasting durability, and resistance to breakage. Non-slip Rubber Chuck: Featuring a polyurethane rubber design, the stone plate clamp protects stones during lifting while its textured surface enhances grip, securely holding materials in place without risk of slipping. Adjustable Opening for Flexibility: With an adjustable width, these lifting tools conveniently accommodate various stone sizes, enhanced by a safety spring mechanism that prevents slippage during both lifting and lowering. Versatile Industrial Use: Perfect for engineering and construction applications, these industrial lifting tools work effectively with crane trucks to transport a diverse range of materials, including concrete blocks, granite slabs, timber, and metal sheets.
