  • Detailed Description

Engineered for Heavy Equipment Haulage

Transporting large-scale excavators and mining machinery requires a robust foundation. Our low-bed trailers are constructed from high-strength, anti-torsion steel. This prevents structural sagging when carrying concentrated heavy loads, ensuring absolute stability and safety during cross-border transport of oversized cargo.

Optimized Loading & Height Complianc

The ultra-low deck design significantly lowers the center of gravity, which is crucial for safely passing through height-restricted bridges and tunnels. Paired with optional high-power hydraulic ramps, loading and unloading heavy engineering machinery becomes highly efficient, reducing downtime for logistics fleets

What is a low-bed semi-trailer used for?

Definition: A low-bed semi-trailer (also known as a lowboy) is a specialized heavy-haul transport vehicle with a highly depressed deck. It is primarily used to transport oversized, tall, or heavy freight that exceeds standard legal height limits, such as excavators, bulldozers, transformers, and large industrial components.

Low-Bed Trailer vs. Flatbed Trailer

Feature Low-Bed Trailer (Lowboy) Standard Flatbed Trailer
Deck Height Ultra-low (dropped between axles) High (sits above the tires)
Primary Cargo Tall heavy machinery, excavators Shipping containers, steel coils
Loading Method Via rear ramps (drive-on)

Via cranes or forklifts (lift-on)

 

How to choose a low-bed trailer for excavator transport?

  • Assess Payload: Determine the maximum weight of your excavators to select the correct axle count (e.g., 3-axle for 60T, multi-axle for 100T+).

  • Check Deck Height: Ensure the loaded height complies with local highway bridge clearance regulations.

  • Select Ramps: Choose hydraulic ramps for heavy excavators to ensure safe and effortless loading.

  • Verify Steel Quality: Require high-tensile steel to prevent chassis deformation over time.
