Line-handling block comprising two cheeks having bayonet mating interconnection |
摘要 |
A block for line-handling comprises two cheeks and a rotatable sheave sandwiched between the two cheeks. The two cheeks mate together through a central aperture of the sheave by a relative rotation of the cheeks via a bayonet fitting. The mated cheeks are secured to each other by fixing pins, which also secure a swivel attachment member to the block. Bearing elements are used for rotatably supporting the sheave to prevent its translational movement relative to the cheeks.
