Represents the most advanced design work to blend form and function together into a new shear reduction pulley. The main frame, back up shield and axle are manufactured from 304 stainless steel. The 4” diameter heat treated 6061 T6 aluminum sheave is pared from any excess weight while the stainless frame surrounds the sheave with minimal surface contact. The stainless steel axle supports the assembly and gives The Stargate its 12,000 Lb. rating. Unlike other designs, the Stargate’s helix wheel can be rotated 180 degrees in the field to extend its useful life. The Stargate uses only the very best components and material so you know that your investment is secure.
