PERFORMANCE
Purui can provide all kinds of crane hook blocks, including light hooks (0.5t-20t), heavy hooks (20t-500t), forged hooks, laminating hooks, and specialized hook sets for special conditions. All crane hook models can be customized, including load capacity and color. We support factory SGS inspection before shipment. Our technical team can provide you with the best lifting solutions. For product selection or technical consultation, please feel free to contact us.
High load-bearing and safety
The design load covers 5-200t working conditions, and the safety factor is ≥2.5 (static load); Standard anti-rope derailment device (baffle or rope presser) complies with GB 6067.1 safety regulations to eliminate the risk of wire rope derailment.
High transmission efficiency and low wear
The rolling bearing has a low friction coefficient (0.001-0.003), a transmission efficiency of ≥95%, and energy consumption is more than 20% lower than that of sliding bearings; The surface roughness of the rope groove is Ra≤6.3μm, and with high-quality steel wire rope (such as galvanized or compacted strands), the wear rate is ≤0.1mm/thousand cycles.
Strong environmental adaptability
Temperature range: -30℃~+80℃ (ordinary type), low temperature resistant (-40℃) or high temperature resistant (+120℃) materials can be selected for extreme environments; Protection level IP54, dustproof and waterproof, suitable for dusty, humid, and open-air scenes; The explosion-proof type complies with GB 3836 standards and is suitable for flammable and explosive environments such as chemical industry and coal mines.
Convenient maintenance
The bearing seat is equipped with oil filling/draining holes to support non-stop lubrication; The modular design facilitates overall replacement, and the maintenance time is shortened by more than 50% compared with non-standard components.
PURPOSE
Manufacturing and Heavy Industry: Used in machining, assembly workshops, and steel mills (casting cranes, clamp cranes), they handle raw materials, semi-finished products, and heavy equipment. Logistics and Ports: Used in port terminals for container gantry cranes, yard cranes, and portal cranes, they are key links in the global logistics chain. Construction: Tower cranes, construction elevator winches, and other equipment are indispensable equipment for modern construction. Power and Energy: Used in hydropower, thermal, and nuclear power plants for the installation and maintenance of large equipment such as generators and turbines (typically using high-safety cranes). Mining and Metallurgy: In mine hoists, drums (often called winches or friction sheaves) are responsible for lifting cages or personnel from shafts hundreds or even thousands of meters deep, representing one of the most demanding safety applications. Shipping and Offshore: Used in shipyard gantry cranes and ship deck cranes for shipbuilding, repair, and cargo loading and unloading. Water conservancy and municipal engineering: Hoists used for sluice gates and dams, which raise or lower the gates by retracting and releasing the wire rope on the drum.
