▶【DAMAGE-FREE WORKPIECE】Equipped with wear-resistant non-slip jaws, this lifting clamp securely grips steel plates, I-beams, and pipes without scratching or damaging -surfaces. The screw clamping mechanism distributes pressure evenly, eliminating the risk of workpiece deformation. ▶【RELIABLE SELF-LOCKING MECHANISM】Our vertical plate clamp features a precision trapezoidal thread with a T-handle for easy adjustment. The self-locking design prevents accidental loosening during lifting, ensuring the clamp stays firmly engaged even under heavy loads and vibration. ▶【DURABLE CONSTRUCTION】The one-piece forged body and anti-corrosion coating resist impact, wear, and rust,can withstand repeated use in harsh industrial environments, reducing maintenance needs and replacement costs. ▶【INDUSTRIAL-GRADE】Manufactured from high-strength forged alloy steel with heat treatment, our screw lifting clamp meets strict safety standards. The 1.5Ton/3Ton rated load capacity and 0-32mm/0-50mm grip range make it ideal for heavy-duty lifting. ▶【MULTIPLE APPLICATIONS】Perfect for vertical/horizontal lifting of steel plates, profiles, and structural components in workshops, construction sites, shipyards, and more. Works seamlessly with cranes, hoists, and lifting chains for various industrial tasks.
