Trailer Landing Gear Manufacturer: Stability Engineered for Every Load
When a 20-ton trailer disconnects from its tractor, all that weight rests on one system — the landing gear.
A failure here can cause a collapse, damaged cargo, and even injury. That’s why trailer landing gear is more than a simple support device; it’s a structural safeguard, designed to keep fleets stable and operators safe.
Zhongteli, a professional trailer landing gear manufacturer, specializes in forging and machining landing assemblies that deliver strength, smooth operation, and long-lasting protection against corrosion, vibration, and mechanical fatigue.
The Real-World Pain Point: Support That Never Fails
For logistics operators and trailer OEMs, landing gear reliability defines operational safety.
When used daily under dust, rain, and mechanical stress, a substandard system quickly reveals its flaws.
Frequent Industry Problems Include:
-
Weak weld seams causing frame bending
-
Gearbox seizure after exposure to moisture
-
Uneven leg extension leading to tilt or collapse
-
Corrosion reducing load-bearing strength
As SAE International mechanical standards highlight, proper torque distribution and shaft alignment are essential in high-load landing systems. Zhongteli’s products follow these standards to ensure safe static support and balanced lifting under any condition.
Trailer Landing Gear vs. Standard Support Systems
| Feature | Trailer Landing Gear | Standard Support Jack |
|---|---|---|
| Load Capacity | 20,000–80,000 lbs | 2,000–10,000 lbs |
| Operation | Dual-speed gearbox | Single gear or manual screw |
| Durability | Industrial forged steel | Mild steel / cast components |
| Use Environment | Heavy trucks, tankers, cargo trailers | Light utility or small trailers |
| Stability | Dual-leg synchronized | Single-leg / manual adjustment |
Unlike regular jacks, landing gear systems are built for synchronized, high-torque lifting — essential for large freight trailers and tankers where balance determines safety.
