1.High strength: Forged alloy steel resists fatigue and impact.
2.Efficient lifting: Precision crane hook block sheaves improve hoisting speed.
3.Custom adaptability: Sizes and crane hook block parts adjustable to suit different cranes.
The applications of crane hook blocks cover overhead crane hook block for workshops, tower crane hook block for construction lifting, crawler crane hook block for mining and metallurgy, and mobile crane hook block for ports and logistics.
1.Hook design: Streamlined to reduce stress concentration, flaw detection ensures no cracks.
2.Pulley system: Durable sheaves with smooth grooves minimize wire rope wear; sealed bearings extend service life.
3.Connection structure: High-strength bolts with preload prevent loosening; lightweight design reduces crane load.
