The Thieman LRST: A Heavy-Duty Tuck-Under Liftgate Built for Reliability
All about Thieman LRST Series Liftgate
When it comes to dependable performance in the world of liftgates, the Thieman LRST stands out as a top-tier tuck under lift gate designed for medium and heavy-duty applications. Built for trucks and trailers, this Thieman tailgate combines robust engineering with thoughtful features that enhance safety, reliability, and ease of use.
Built for Heavy Loads and Tough Conditions
With a 4,000 lb. lifting capacity, the LRST is made to move serious weight. Whether you’re hauling freight for local deliveries or large cargo for long-hauls, this liftgate handles it with confidence.
- Dual lift cylinders provide consistent, stable lifting.
- Large 80" x 60" aluminum platform accommodates bulky or wide loads.
- Heavy-duty steel frame ensures long-term durability.
Self-Leveling for Safer Operation
One of the key benefits of the LRST is its self-leveling action, which automatically adjusts the platform to stay parallel with the truck bed. This ensures safe and smooth loading or unloading, even on uneven surfaces.
- Prevents tilting during lowering or lifting
- Reduces risk of cargo tipping
- Makes operation simpler for drivers
Low-Maintenance Design
Downtime is costly. That’s why Thieman designed the LRST with components that reduce maintenance frequency:
- Self-lubricating Teflon bearings at all pivot points
- Grease-able pin option for fleets that prefer manual upkeep
- Retracted cylinder rods protect from debris while in transit
- Plastic pump enclosure shields electrical components from weather
These features not only extend the life of the liftgate but also cut down on unexpected service needs.
Smart Electrical and Hydraulic Systems
Meeting TMC electrical guidelines, the LRST comes with a sealed toggle or push-button switch, a 150-amp circuit breaker, and a 12VDC power system. Hydraulic power is controlled through an efficient dual-cylinder design, with options for cold-weather fluid and flow control valves for reliable year-round operation.
Customization Options
Thieman offers a variety of upgrades for the LRST, allowing you to tailor it to your specific use case:
- Optional rear impact guard (compliant with FMVSS 223, 7/15/2024)
- Dock bumpers with cable step
- Foot-activated cart stops (single or dual)
- Galvanized finish for corrosion resistance
- Remote pendant control and in-cab shutoff switch
Ideal for Fleet and Trailer Applications
With a bed height compatibility of 46" to 56", the LRST fits a range of trucks and trailers. It’s particularly well-suited for:
- Van bodies
- Stake bodies
- Semi-trailers (with optional mounting kits)
Final Thoughts
The Thieman LRST tuck-under liftgate is a top-tier option for anyone needing a rugged, reliable, and low-maintenance solution for frequent heavy lifting. Engineered with user safety, longevity, and serviceability in mind, this model delivers consistent performance, load after load.
