MADISON, Ind. (Aug. 21, 2015) — Rotary Lift has received a U.S. patent for its technician-friendly Trio vehicle lift arms.
The company, a Vehicle Service Group (VSG) brand, said it was granted Patent No. 8,973,712 for the Trio arms that have up to a 20-percent greater reach than traditional lift arms. That enables the unit to be used to service a wider range of vehicles. The proprietary three-stage design enables technicians to more easily move the arms into position and then precisely position adapters exactly where they're needed for proper lifting, according to Madison-based Rotary Lift, which noted that the Trio arms come standard on its Rotary Lift SmartLift 10,000-pound capacity inground lift.
Rotary Lift introduced the original three-stage arm in North America in 2005, with the original arms consisting of three telescoping sections that slid inside of each other so they could be extended or retracted as necessary to reach more vehicle pick-up points than was possible with traditional lift arms.
Rotary Lift claims the original three-stage arm design has been widely copied and is now available on many light-duty two-post surface and inground lifts, “but Rotary Lift engineers were not satisfied. Rotary Lift invented the original hydraulic lift in 1925, and over the last 90 years the company has had a singular focus on developing the most efficient, reliable and longest-lasting lifts for its customers.”
In 2011, the company introduced what it deemed an even better three-stage arm — the Trio. Its arm design keeps the first two telescoping arm sections and replaces the third with a multi-position sliding adapter integrated into the second arm. Rotary Lift said this design lets techs easily interchange truck adapters, round polymer adapters or three-position flip-up adapters depending during a job. They can easily rotate the adapters 360 degrees and can slide them from a fraction of an inch to several inches to precisely position them at the proper pick-up points.
“Trio arms have the most advanced arm design around,” said Jim Dirksen, vice president of light-duty for Rotary Lift. “Their versatility, ease-of-use and precision makes them very popular with technicians, service managers and shop owners. A single lift equipped with Trio arms can service practically any vehicle under 10,000 pounds, from a unibody car to a light-duty pickup.
“As the technician population ages, bay ergonomics become increasingly important. It's easier to slide just one telescoping arm and then move an adapter than it is to slide two heavy arm sections. Plus, with today's vehicle designs, it's more important than ever that technicians lift a vehicle only at the OEM-designated lifting points. No other lift arm out there offers the fine adapter adjustment made possible by our Trio arm design.”
Trio arms were designed by Rotary Lift engineers in Madison, and the company said they have been performance-tested to 20,000 lift cycles — equivalent to 10 years of real-world use. Rotary Lift added that all of its SmartLift inground lifts are third-party tested and Automotive Lift Institute (ALI) certified to meet ANSI lift safety and performance standards.
VSG, part of the Engineered Systems segment of Dover Corp., comprises nine global vehicle lifting and collision repair brands: Rotary Lift; Chief Automotive Technologies; Forward Lift; Direct-Lift; Hanmecson; Revolution Lift; Elektron; Blitz; and nogra.
