STARGATE SRD -Shear Reduction Device

The "Stargate" represents the most advanced design work to blend form and function together into a shear reduction pulley. The main frame, back-up shield and axle are manufactured from 304 stainless steel.  The 4" aluminum sheave is hard anodized and 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.
