起重机钩和块

Crane hooks and blocks are core components in industrial lifting operations and are designed for heavy-duty lifting, precise positioning and long-term durability. This product uses advanced materials and manufacturing processes, combined with intelligent safety technology, and is suitable for heavy equipment handling needs in construction, 端口, 制造业, energy and other fields, ensuring both operational efficiency and personnel safety.

Product features of crane hook and block

Ultra-high strength and durability

• Materials Science:

  • 钩: Forged from alloy steel (such as S355/S690), after quenching + tempering treatment, the tensile strength is ≥800 MPa, and the toughness is increased by 30%.

  • Pulley block: The pulleys are made of wear-resistant cast steel or engineering nylon composite materials, embedded with high-precision deep groove ball bearings, reducing the friction coefficient by 40%.

• 表面处理:

  • Hot-dip galvanized or sprayed with epoxy resin coating, resistant to salt spray, acid and alkali corrosion, and suitable for harsh environments such as ports and offshore platforms.

Intelligent security protection

• Overload protection: integrated electronic sensor (选修的), real-time monitoring of load, automatic locking and sound and light alarm when overloaded.

• Mechanical insurance: The standard rotating safety tongue prevents the wire rope from accidentally falling off; the hook neck is designed with a stress dispersion structure to avoid stress concentration and fracture.

Modular and flexible configuration

• Supports free combination of single pulley to 6 pulley groups, adaptable load range from 1 到 500 吨.

• Quick-release connection design eliminates the need for special tools when replacing accessories, reducing maintenance time by 50%.

Lightweight and energy-saving design

Through topology optimization and finite element analysis (fea), the dead weight is reduced by 15% under the same load, reducing the energy consumption of the crane.
