Recently, Rotary distributed a document favorably comparing a Rotary two-post hoist to a BendPak two-post hoist. Never ones to back down from a challenge, the BendPak engineering team responded the only way they knew how—with a thorough investigation of their own. After exhaustively reviewing the merits of both BendPak and Rotary standard 10,000-lb. capacity asymmetric two-post hoists, BendPak released the following report. In it, critical design features are compared, evaluated and illustrated in broad detail. The findings were enlightening, to say the least.

Hydraulic Cylinder / Rod End

Throttle valve opens to 100% max pump flow during lift rise, then close and reduce flow during descent.

BendPak Cylinder

Hydraulic Cylinder / Thickness

BendPak hydraulic cylinder offers 5/16" wall thickness with an integrated throttle valve vs. Rotary's 3/16" wall thickness with no throttle valve.

Rotary Cylinder Thickness

Hydraulic Cylinder / Full View

The comparable BendPak cylinder offers offers a full extra inch of stroke.
