Product description

The Challenger 40050 Sheave is a heavy-duty cable pulley essential for the synchronized lifting mechanism of 12,000 lb. capacity four-post lifts. This precision-machined sheave guides the 7/16-inch diameter lifting cables through the runway, ensuring smooth and level vehicle ascent. Over time, cable sheaves can develop grooves or flat spots, which increases friction and leads to premature cable wear or uneven lifting. Replacing worn sheaves with this high-strength assembly restores the smooth operation and safety of your heavy-duty lifting equipment. It is designed to handle the extreme loads required for servicing trucks and large commercial vehicles.
