Special Semi-Trailer Configurations
Shown: Lowboy, extendable and SPMT types (other heavy-haul layouts available) — deck height, axle lines and steering are all customizable to your oversize cargo.
About this Special Semi-Trailer
Our special semi-trailer range covers the heavy-haul jobs ordinary trailers cannot do. A hydraulic detachable gooseneck (HDG) Lowboy carries ultra-low, concentrated loads; an extendable flatbed/lowbed stretches to 30 m+ for wind towers and long pipes; and SPMT modules self-propel and steer in any direction for tens-of-thousands-of-tonne pieces. Built in Liangshan — China's trailer manufacturing hub — every unit is engineered to your cargo and the road-permit limits of your destination country.
These are oversize/overweight transports that usually require route surveys and permits; we size axle lines, deck height and steering to your project.
Other Common Sizes & Configurations
Beyond the standard build, we make these Special Semi-Trailer variants to match different cargo and routes — all sizes, axle counts and capacities listed above are configurable to your specification:
- Lowboy (HDG) — deck 560–610 mm, 32–150 t single unit
- Extendable — 14–18.5 m stowed, 30–33.5 m stretched

How the Special Semi-Trailer Compares
Not sure which trailer type fits your cargo? Here is how the Special Semi-Trailer differs from close alternatives.
vs Lowbed Semi-Trailer
Special is the extreme end — Lowboy (HDG) with sub-600 mm deck, extendable to 30 m+, or self-propelled SPMT; the Lowbed Semi-Trailer is the general low-platform range for standard oversize loads.
vs Flatbed Semi-Trailer
Special carries ultra-heavy,超长 or超重 pieces that a flatbed cannot; the Flatbed Semi-Trailer is a fixed-length general deck.
vs Dump Semi-Trailer
Special moves oversize machinery and structures; the Dump Semi-Trailer tips bulk material. Different cargo and duty entirely.
