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.
Column / Front
BendPak's single-piece columns result in a stronger, longer-lasting structure.
Column / Side
Note the difference in thickness between BendPak and Rotary.
Column / Rear Bottom
BendPak's larger base offers a more stable lift.
Column / Bottom Sheave
Increased sheave size and support.
Column / Base Plate
Thicker base plates for maximum stability.
Column Assembly / BendPak® on Scale
BendPak offers heavier-duty, more rugged design.
Column Assembly / Rotary® on Scale
Rotary column less heavy-duty than BendPak.
Carriage / Front
Taller lift carriages reduce column stress and increase the hoist's lifespan.
Carriage / Rear
BendPak locks are built into the full carriage, not included as a less stable extension piece.
Carriage / Top View
Top view of BendPak's taller lift carriage.
Carriage / Top Dimensions
Wider carriage dimensions on BendPak.
Carriage / Safety Lock Thickness
BendPak safety locks are significantly thicker and better-built.
Carriage / UHMW Slide Blocks
More slide blocks, more reliable design.
Carriage / Pin Hole Location
Reinforced top at carriage's pin hole location
Carriage / Arm Attachment Location
Taller arm attachments.
Carriage / Top Plate Thickness
Thicker top plates on the lift carriage.
Carriage / Arm Restraints
Taller, more tightly designed restraints within carriage,
Carriage / BendPak® on Scale
BendPak lifts feature heavier-duty lift carriages.
Carriage / Rotary® on Scale
Rotary's smaller, less heavy-duty carriage
Arms / Side Detail
BendPak displays a more robust arm design from the side.
Arms / Side Detail
Sturdier arm restraints with longer locking pin.
Arms / Reach / Retracted
Retracted arm comparison.
Arms / Reach / Extended
More reach with BendPak with arms fully extended.
Arms / Construction
Difference in thickness of arm construction.
Arms / Construction / Thickness
Thicker steel in each stage of telescoping arm to improve longevity.
Arms / Construction / Method
BendPak uses superior structural tubing vs. Rotary's multi-piece formed steel.
Arms / Construction / Underside
Great view of BendPak's overall arm construction compared to Rotary.
Arms Set / BendPak® on Scale
Arms that are made to last.
Arms Set / Rotary® on Scale
Smaller and lighter in build than BendPak
Top Beam / Sheave Detail
BendPak offers oversized sheaves to last longer and cost less over time.
Top Beam / Beam Construction
BendPak single-piece boxed channel beam construction vs. Rotary multi-piece construction.
Top Beam / Top View
Wider, improved top beam construction with BendPak.
Hydraulic Cylinder / Rod End
Throttle valve opens to 100% max pump flow during lift rise, then close and reduce flow during descent.
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.
Hydraulic Cylinder / Full View
The comparable BendPak cylinder offers offers a full extra inch of stroke.
BendPak uses larger 3/8" diameter cables (compared against Rotary's smaller 5/16" cable), as well as a larger threaded connector with an increased adjustment range.
Massive cable sheaves reduce wear on all moving components and result in a lower cost of ownership.
