Chain Gin, 5 in (127 mm) Exteded Base

A versatile tool for hoisting distribution transformers and apparatus up the structure. The 5" extended base model allows mounting to bridge up to 4" x 5" crossarms. A wheel tightener and 36" chain is a part of each unit. This model has a 2000 pound maximum rating, including hand pull force. With a single hoist line through a pulley on the gin and a sheave near the base of the structure, the lift load is 900 pounds (lift load plus the pull load equals the capacity). Using 4-4 blocks, the lift load can be 1,400 pounds. A swivel-hook block should always be used in the eye of the gin, and a sheave or a capstan near the bottom of the structure should be used to thread the handline through. Gins are not intended for applications involving side pull on the hoist line, or with the lift load in a tagged out position. That is, the load line should be parallel to the gin pole. Pole length: 26 inches.
