Trailer Lift Jack: Reliable Vertical Support for Every Hauling Task
Every trailer operator knows — a reliable lift jack is more than a convenience; it’s a safety essential.
A trailer lift jack provides vertical support that keeps trailers stable during loading, coupling, and maintenance, preventing frame damage and ensuring operator safety.
Zhongteli, a professional manufacturer of forged trailer components, designs lift jacks that combine structural strength, smooth motion, and corrosion resistance to handle demanding working conditions.
Why Reliable Lifting Matters
Lifting systems are subject to constant stress. Inconsistent or weak jacks can cause misalignment, jack failure, or even load tipping.
Typical Problems with Low-Quality Jacks:
-
Thread binding due to poor machining
-
Tube bending under uneven load
-
Rust and corrosion reducing load capacity
-
Inaccurate height adjustment
-
Base plate instability on rough ground
According to SAE International standards, consistent torque performance and thread precision are critical to ensuring stability and preventing load drift during vertical lifting.
Comparing Trailer Lift Jacks by Type
| Type | Load Range | Main Advantage | Typical Use |
|---|---|---|---|
| Manual Lift Jack | 2,000–5,000 lbs | Simple, durable, no maintenance | Utility or light cargo trailers |
| Drop Leg Jack | 5,000–8,000 lbs | Adjustable height, quick setup | Farm and construction trailers |
| Dual Gear Lift Jack | 8,000–12,000 lbs | Smooth torque control | Industrial heavy-duty transport |
| Electric Lift Jack | Variable | Automation, easy operation | RVs, OEM integrated systems |
While electric jacks are growing in popularity, mechanical trailer lift jacks remain the top choice for professionals who prioritize strength, reliability, and easy maintenance.
