Recently, Rotary distributed a document favorably comparing a Rotary two-post lift to a BendPak two-post lift. 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 lifts, 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 lift'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.

Equalizer Cables

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.

Cable Sheaves

Massive cable sheaves reduce wear on all moving components and result in a lower cost of ownership.

Power Unit

Superior electric-hydraulic power units with BendPak.
