Core Parameters and Tensile Performance This 4-ton heavy-duty manual cable puller is equipped with a thickened and extended Φ4mm high-tensile steel cable with a length of 13.12 ft (about 4 meters). It has excellent tensile strength and deformation resistance, making it sturdy and durable, and can stably bear heavy load requirements. Material Technology and Applicable Environment Made of full steel structure with a hot-dip galvanized finish on the surface, it has excellent rustproof, wear-resistant and weatherproof performance. It can easily withstand harsh conditions such as rain, snow, humidity and complex construction sites, suitable for various indoor and outdoor scenarios, and has a long service life. Safety Protection Design Upgraded with a dual-layer ratchet pulley and double lock claw dual locking structure, this tool can evenly disperse tension and ensure jamming-free operation under heavy loads. The built-in anti-reverse and anti-loosening mechanism effectively prevents steel cable springback, reverse movement and accidental disconnection, eliminating the risk of heavy goods slipping and ensuring full working safety. Convenient Operation and Labor-Saving Design The optimized ratchet transmission system enables smooth one-hand operation with seamless pulling and tightening movements. The extended non-slip labor-saving handle offers a comfortable grip and effortless force output, reducing fatigue during long-time work and greatly improving work efficiency. Standard Accessories and Connection Performance It comes with two high-strength forged steel hooks as standard, each fitted with a spring anti-drop buckle. The thickened and reinforced hooks are high in toughness and stable in load capacity, not easy to bend, and can meet multi-angle needs for traction, fixing, hoisting and other connection work. Multifunctional Uses and Applicable Scenarios Compact, lightweight and easy to store and carry, this multifunctional manual winch is widely applicable to various scenarios such as off-road rescue, vehicle towing, fence tensioning, heavy object moving, garden logging, construction work, farm breeding, garage maintenance and household DIY projects. It is an essential all-in-one traction and lifting tool for industrial operation, outdoor work and daily repair.
