ANSI/ALI ALCTV‐2006 CERTIFIED PRODUCT
Dare to Compare / Separating Fact from Fiction
In the highly competitive auto lift business, especially the DIY sector, many judgments are being passed on with no merit based solely on uneducated bloggers being sold on creative marketing. Always study thoroughly, then look,
Full Range of Lift Models to Chose From
BendPak has 72 unique lift models ranging from lightweight to super‐duty. Many “hobby” lift companies could not come close to a fraction of lifts BendPak sells globally. Investigate thoroughly on the web using various search engines to see how many pages other lesser known lift companies appear on compared to a true world‐leader like BendPak.
Optional Equipment
Many valuable options are available for your BendPak four‐post lift.
Service is our Specialty
BendPak has over 650 installation and service centers located in the United States. These fully equipped installation and service centers have specialty service fleets that make a living installing and servicing large car dealerships, national accounts, auto repair centers and occasional auto enthusiasts and DIY’ers.
Engineering Excellence
BendPak has a staff of seven full‐time engineers who do nothing but design, test, and evaluate lift systems. BendPak lifts have changed and evolved over the past 40‐years not because they like making changes but because they are constantly improving the structural integrity and design of our lifts to meet constantly changing world standards. On the surface, many lifts look “engineered”, but w
hat lies under the surface? All BendPak lift designs are computer modeled for design function and structural integrity then undergo simulation of applied forces, axial force, bending moment, etc. using Solid Works Cosmos and other FEA programs. After the design is sound, they proceed with actual destructive (physical) testing.
There is only one real national lift standard for quality and safety ‐ OSHA endorsed ANSI/ALI ALCTV‐2006. If you don’t see any reference to this standard, then ask yourself if saving a few extra bucks on a non‐certified lift is really worth jeopardizing the safety of you and your loved ones. BendPak gives you value, but more important, a peace of mind.
ETL Certified
Why are other lesser known lifts not approved to meet the requirements of ANSI/ALI ALCTV‐2006? ‐ Quite simply, because their lifts could not pass the standard. Particularly their lack of a slack‐cable lock system, a substantiated engineering report from an accredited PE (professional engineer) verifying that all components could withstand a load of 150% capacity with no permanent yield or deformation of any kind, their absence of an ample cable guard to prevent unintentional displacement, and more.

汽车举升机Common Misleading Claims
•Claims that state "Meets or Exceeds Standard ANSI/ALI B‐153.1" are meaningless. This standard no longer exists.
•Claims that state "Meets all ANSI Standards" are meaningless. No other standards apply to lift construction except ANSI/ALI ALCTV. In order to meet ANSI/ALI ALCTV, Certification is required. Look for the Mark.
•Claims that state "Meets all OSHA Requirements” are meaningless. OSHA has no requirements governing automotive lifts, but they do write citations applying to automotive lifts. They do this under the General Duty Clause and recommend to those cited that it would be prudent for the cited party to follow the directives in the various standards developed by ALI.
•Any claim that implies "This lift is ALA Certified" is worthless. ALA (Automotive Lift Association) is re
ported to be an organization of suspect lift suppliers with no endorsement by ANSI or OSHA. ALA appears to be purely fictitious and created merely to confuse purchasers, users and inspectors.
•Any claim that implies "This lift is MAMTC Certified" is worthless. MAMTC (Mid‐America Manufacturing Technology Center) is a unit of Wichita State University which, in one instance, attempted to certify a lift model. Test Reports on MAMTC letterhead stated that a particular lift complied with ANSI B153.1 – 1990. Of course this is meaningless because MAMTC is not a NRTL (Nationally Recognized Test Facility), and the standard cited is obsolete.
Safety First
BendPak lifts incorporate UHMW (Ultra‐High Molecular weight) Polyethylene glide blocks to maintain proper alignment of lifting and safety components. UHMW is often referred to as the world’s toughest polymer. UHMW is a linear high density polyethylene which has high abrasion resistance as well as high impact strength. UHMW is also chemical resistant and has a low‐coefficient‐of‐friction which makes it highly effective in a variety of applications. BendPak glide blocks are simply guides that keep the cross tubes and safety ladder centered within the column and minimize sway.
Designed for Longevity
BendPak lifts feature cable sheaves that are precisely centered within the cross tube meaning the cross tube tends to stay level during the entire lifting motion thereby eliminating side loads of any kind. Lesser know lift brands employ cross tube sheaves and axles that are located outside the cross tube body forcing the cross tubes to twist or rotate away from the sheave as the lift raises. This twisting occurrence tends to develop side‐loading on their cross tube components and plastic sliders.
Hydraulic Cylinder Design
All of BendPak lift cylinders use internal flow‐restrictors to prevent rapid fall in case of a hose or fitting failure. This is a worldwide safety standard that is required for all commercial lift manufacturers. International lift standards prohibit the use of quick‐disconnect fittings on vehicle or personnel lift applications. Quick disconnect fittings have spring loaded ball‐in‐seat components. If the ball does not “seat” like you expect it due to contamination or faulty ball‐seat, there is nothing to shut off the flow of oil and the uncontrolled descent of your lift. Hose “blow‐outs” simply do not occur under normal use. As part of the ANSI/ALI ALCTV‐2006 standard all BendPak hoses have a 400% safety factor based on the pressure required to operate the lift at its rated load capacity.
BendPak HD‐9 series lift models feature a single 3” diameter hydraulic cylinder hidden away under the runway for maximum performance, reliability and minimum exposure to the elements. Our industrial‐grade hydraulic cylinders feature a one‐piece, pilot fitted, machined steel piston wrapped with specially designed, pressure loaded U‐cup piston seals, backups and wear bands that virtually eliminates any fluid bypass. The micro‐smooth chrome‐rod is machined from high yield, ground & polished C‐1045/50 micro‐alloy steel and plated to a minimum of .001˝ diametrically, to ensure superior cylinder operation and life. Specially designed, high durometer, mechanically loaded rod seals virtually eliminate rod seal leakage and a specially formulated abrasion resistant urethane rod
wiper provides exclusion protection. The welded cylinder body is made from high yield‐strength steel tubing produced to exceed ASTM specifications. This combination of superb base material and superior processing ensures straight, smooth and long duty life cylinders.
Redundant Safety Lock System
BendPak four‐post lifts employ eight independent safety lock devices ‐ four primary and four back‐ups.
BENDPAK SAFETY LOCK SYSTEM FEATURES SLACK‐CABLE BACKUP
Adjustable Safety Locks
BendPak’s adjustable ladder provides adjustment for unlevel floors enabling your vehicle to sit safely in a level position even if your floor is unlevel ‐ an important feature that other lift brands lacks. BendPak features 13 adjustable lock positions providing greater versatility and storage height coverage.
BENDPAK ADJUSTALBE LOCK STOPS OTHER BRANDS ‐ FIXED LOCK STOPS
Commercial‐Grade Pneumatic Safety Lock System
Our commercial‐grade pneumatic safety lock system ensures that your locks release simultaneously every time. Other lifts use linkage rods to release the four spring loaded locks – that means a lot of resistance to overcome. That combined with the accumulation of slop for all of the linkage points means that the safety lock furthest from the operator has a good chance of not being “pulled back” far enough. Think about what would happen if three corners descended and one stuck. The worst cause of lift failures or vehicle “drops” are caused by the runways becoming unlevel due to seized column or stuck lock. Mechanical linkage systems are more prone to failure.
