Crane Double Hook

Crane double hook can share the load at the same time and balance the load of the crane hook. Compared with the single hook of a crane, it has higher safety and has become a core component in the field of heavy lifting.

Carrying capacity: 1-200 tons
Material: alloy steel (such as 34CrMo4, 42CrMo, tensile strength ≥800MPa)
Opening size: 50~300mm
Applicable wire rope diameter: 10~60mm (needs to match pulley groove radius, usually groove diameter ≥ 1.1 times rope diameter)
Certification standards: DIN 15401, ISO 2415, CE certification, CMA/CNAS

Crane double hook parameters

Load	Single hook load: 1~50 tons (conventional industrial grade), Double hook cooperative load: 50~200 tons (needs to cooperate with balance beam or special design)
Material	Main material: alloy steel (such as 34CrMo4, 42CrMo, tensile strength ≥800MPa), Special environment: stainless steel (316L), galvanized steel or high temperature resistant steel (such as 15CrMoV)
Opening size	50~300mm
Safety factor	≥4
Working temperature	Conventional type: -40℃~+200℃, High temperature resistant type: -20℃~+450℃ (special alloy + thermal insulation coating)
Own weight	Single hook weight: 50kg~2 tons (as the load capacity increases, for example, the weight of a 50-ton hook is about 1.8~2.2 tons)
Applicable wire rope diameter	10~60mm (needs to match pulley groove design)

Advantages of Weihua crane double hook structure

1. More balanced load distribution: crane double hook can suspend two loads at the same time (or share a single large load through the balance beam), disperse the stress points, reduce the stress concentration of a single hook, and improve safety. Suitable for asymmetrical or unstable loads to avoid the risk of tilting.
2. Improve efficiency: The crane’s double-hook design enables the crane to handle two objects at the same time, thereby significantly improving operating efficiency. In busy logistics centers or construction sites, this design can greatly reduce operation time and improve overall productivity.
3. Security: If a single hook fails (such as accidental decoupling), the other crane hook can still provide partial support, reducing the risk of accidents.
4. High load: Weihua crane’s double hook load is up to 200 tons and is often used for heavy-duty crane loading and unloading work.

Weihua crane double hook application

1. Weihua crane double hook for heavy industry: steel plants (lifting steel coils and plates), shipyards (section assembly), large machinery manufacturing.
2. Weihua crane double hook for construction industry: installation of bridge components and hoisting of precast concrete panels.
3. Weihua crane double hook for port: double hook coordinated lifting of containers and bulk cargo.
4. Weihua crane double hook for energy: precise positioning of wind turbine blades and nuclear power equipment.
5. Weihua crane double hook for special environment: high-temperature workshops (heat-resistant materials are required), corrosive environments (such as coastal ports using stainless steel or coating).
