Chain Binder Type Transformer Gins - A “must have” tool for hoisting equipment into position on a pole. These gins are made up of a lifting eye, mast, chain binder and base. The C400-0090 has a standard base that permits installation on a pole that offers no obstruction that may interfere with proper installation or operation. The C400-0315 has an extended base that facilitates the clearance of pole obstructions including a 4” x 5” crossarm.
Both models have a 3”’ diameter, 26” mast, 36” chain binder and have a 2,000 lb. working load rating.
When determining the force put on the gin’s lifting eye both the load and the pulling force must be considered. If a single block is attached on the gin’s eye and a 200 lb. transformer is being lifted - the force on the eye is 420 lbs. (including load x 10% to allow for single sheave block friction.)
Therefore the maximum load that may be lifted with a single sheave block is approximately 950 lbs.
Example: (950 x 2) + (950 x 10%) = 1995 lbs.
Working Load: 2,000 lbs.
Mast Length: 26”
