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.
Load | Single hook load: 1~ 50 tonnellate (conventional industrial grade),
Double hook cooperative load: 50~200 tons (needs to cooperate with balance beam or special design) |
Materiale | 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) |
