Crane Collar
Crane collars are metal fittings used to secure wire ropes in lifting machinery, primarily serving to connect, reinforce, and protect them. The following is a detailed description:
Material and Classification
Crane collars are typically made of cast steel (such as Q235B carbon structural steel, 15/35 high-quality carbon steel, or KTH370-12 malleable cast iron) and are hot-dip galvanized for corrosion resistance. They are classified by load capacity into two types: general-purpose (GT) and heavy-duty (HT). Heavy-duty collars are designed for use with high-strength wire ropes (nominal tensile strength up to 1870 MPa).
Function and Safety Standards
Protection: The curved design reduces wire rope wear and extends its service life.
Load Requirements: The safe load must be no less than 32% of the wire rope's minimum breaking force, and the inner diameter must retract no more than 15% of its original size after unloading.
Compatible Specifications: Suitable for wire ropes with diameters of 8-65 mm. These are commonly used in port loading and unloading, rail transport, and other applications.
