ForgeFab® sheaves in Spud Pole
Each ForgeFab® sheave begins as a computer driven, precision disc cut from proprietary chemistry alloy steel plate.
The steel disc is heated to forging temperature and its edge rotated against a system of staged rollers to forge the sheave rim and wire rope groove.
A precisely machined hub is arc welded to the forged disc. A variety of welding techniques is used, including: fillet, submerged arc, patrial penetration and full penetration, depending upon the application.
The result – a precision built Forgefab® sheave.
