STRENT LOAD WALL: forged from low carbon alloy steel with high polished surface, strong and durable., through high temperature quenching treatment, the hook is characterized by lifting resistance and high load force. ANTI-CORROSION AND ANTI-WEAR: Powder coating and heat treatment greatly improve the resistance to corrosion and wear. Compared with normal stainless steel, it is more durable, rustproof and corrosion resistant. It can be soaked freely in the rain. WITH SAFETY LOCK: The safety latch design prevents the shoulder strap from falling off. Applicable to factory lifting, port lifting, construction and other industries. NOT EASY TO FORM: Excellent stress and crack resistance, not easy to form. The wide opening design makes it easy to install the ramp. WIDE RANGE OF APPLICATIONS: It can be used for loading and unloading cargo, mining equipment, forestry machinery, land transport, lifting machinery, etc.
