The TOPONE Double Sheave Pulley Block guides fiber rope through two iron sheaves fitted with bronze bushings. Its hot-dip galvanized malleable iron body is available in 3–9 inch sizes, with a swivel eye or hook connection to suit the rigging arrangement.
· Construction: The double sheave pulley block has a hot-dip galvanized malleable iron body, two iron sheaves and bronze bushings. It is designed to guide fiber rope through a two-sheave rigging arrangement.
· Connections: A swivel oval eye or swivel hook can be selected to suit the installation. For an eye connection, choose a compatible shackle rated for the complete assembly.
· Applications: Suitable for specified fiber-rope lifting and pulling arrangements in construction, workshops, warehouses and general material handling.
· Precautions: Check the block’s marked working load, rope diameter and the ratings of all connecting components before use. Account for the load imposed on the block by the rope direction and rigging arrangement; two sheaves do not automatically double its rated capacity. Keep the rope seated in the grooves, avoid side loading, and inspect the body, fitting, bushings and free rotation of both sheaves before each use. Do not use a damaged or unmarked block. thecrosbygroup.com
