Rotary Lift has been granted a U.S. patent for its Trio vehicle lift arms. Trio arms have up to a 20% greater reach than traditional lift arms, so they can be used to service a wider range of vehicles, the company claims.
The lifts’ 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, said Rotary Lift. Trio arms come standard on the Rotary Lift SmartLift 10,000 lb. capacity in-ground lift.
Rotary Lift introduced the original three-stage arm in North America in 2005, which consisted 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.
In 2011, Rotary Lift introduced the Trio. The Trio arm design keeps the first two telescoping arm sections and replaces the third with a multi-position sliding adapter integrated into the second arm. This design lets technicians easily interchange truck adapters, round polymer adapters or three-position flip-up adapters depending on the job at hand, Rotary Lift said. 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.
