Efficient handling tools: The vertical plate grippers use a scissor design that enhances gripping force as tension increases, allowing for a wider jaw opening to boost productivity. High-quality alloy steel: The lifting pliers are constructed from durable alloy steel that has been forged at high temperatures, featuring an anti-rust coating for long-lasting performance. Rubber non-slip chuck: Designed with polyurethane rubber, the stone plate clamp protects the stone during lifting and features a textured surface for added friction to prevent slipping. Adjustable opening: These lifting tools come with adjustable openings to accommodate various sizes of stone and include a safety spring mechanism to prevent slipping during use. Versatile applications: The industrial lifting fixture is compatible with crane trucks for tasks like road construction and stone transportation, suitable for lifting concrete blocks, granite slabs, timber, plates, and more.
