STOWAWAY LIFTGATES

The LRST (Level Ride Stowaway) is designed for handling loads of up to 4,000 lbs. and features a self-leveling action and an adjustable platform to provide a stable, “level with truck” surface for all types of loading conditions.

With maintenance being a major concern among fleets today, Thieman has incorporated self-lubricating Teflon bearings at all of the LRST pivot points. The LRST has a unique design so the cylinder rods are retracted during transit to protect them from road debris. The LRST also includes a standard plastic pump enclosure for protection from the weather. All of these features reduce the need for maintenance and keep your trucks and trailers on the road.

Along with a large 80″ x 60″ aluminum platform and self-lubricating bearings, is the industry’s strongest lift frame. This makes the Thieman LRST the most efficient, reliable and durable Level Ride Stowaway in its class.
