Lead sheaves are essential to allow a change of angle to a line from any hoist or winch. With their offset design, Columbia lead sheaves can be bolted down or welded for simple installation at any angle. Fabricated of durable steel, additional features are available such as bolt-on limit switches, Nylatron or steel sheaves. Custom sizes can be supplied.

The supporting frame for the sheave rotates on hollow shafts that ride on pillows on each side of the sheave. The opening in the shaft aligns with the groove in the sheave which allows the line to rotate freely around the axis of the shaft.
If the load should swing or rotate the sheave will remain aligned with it while the section of line from the flag block to the drum stays in proper alignment.
