A lowboy trailer (also called a lowbed trailer) keeps the deck low to the ground so tall, heavy, or oversized machinery can travel under bridge and power-line clearances that a standard flatbed can't. CHENLU builds 3- and 4-axle lowboy trailers rated 30-100 tons, factory-direct from a China-based manufacturer exporting to 30+ countries.
A lowboy trailer — also called a lowbed trailer (lowboy is more common in North American usage, lowbed internationally; both names describe the same trailer type) — is a heavy-haul semi-trailer whose deck sits low to the ground between the front and rear axle groups. The lower deck height reduces the overall height of the load, which helps tall or oversized cargo clear bridges, overpasses, and power lines that a standard flatbed trailer cannot pass under.
A lowboy's gooseneck (the section connecting to the truck) can be either fixed (loaded from the rear via ramps) or removable — see our Removable Gooseneck (RGN) Trailer page for the detachable version, and the comparison further down this page for help choosing between them.
Terminology varies by country and manufacturer. Always compare the deck layout, loading method, axle configuration, and rated capacity rather than relying on the product name alone.

"Rated load capacity" is the trailer's designed carrying capacity under standard conditions, not a guaranteed payload for every route. Available capacity depends on axle configuration, local road regulations, and final engineering confirmation. Final vehicle weight, axle load, permits, and route approval must be confirmed under your destination country's regulations before transport. Pricing is factory-direct and confirmed on inquiry based on your configuration — send us your cargo weight and dimensions for a quote.
Lowboy trailer dimensions vary by manufacturer and configuration, but most units fall within a similar general range across the industry. Use these as a starting reference, then check the exact figures for the model you're considering — CHENLU's own dimensions are in the specification table above.
Figures above are general industry reference points compiled from public heavy-haul trailer guides, not a CHENLU-specific guarantee. As a rule of thumb, adding axles increases total rated capacity but also adds length and turning radius — always confirm final dimensions and capacity against your cargo and local road regulations before ordering.
Axle count is mainly a function of cargo weight, since each axle group has a maximum rated load and local road law sets the ceiling on total combination weight. Use these general starting points, then confirm against your specific cargo and route:
Suited to lighter equipment and shorter machinery where total combination weight stays well within standard road limits. This is a general industry reference, not a configuration CHENLU currently lists as a standard product — ask us about availability.
The most common configuration for mid-size excavators, wheel loaders, and general construction machinery.
Adds axle capacity for larger cranes, mining equipment, and heavier industrial components.
Need to load taller or lower-clearance equipment from the front instead of the rear? See our Removable Gooseneck (RGN) Trailer range, or a lighter, more compact option in our Folding Gooseneck Trailer line. Not sure which fits your cargo? Send us the equipment weight and dimensions and our engineering team will recommend a configuration.
| Fixed Gooseneck Lowboy / Lowbed | Removable Gooseneck (RGN) | |
|---|---|---|
| Loading method | Rear-loading via ramps | Front-loading — gooseneck detaches and lowers to the ground |
| Best for | Equipment that can be driven up rear ramps; general heavy-equipment cargo | Tall or low-clearance machinery that can't climb rear ramps |
| Mechanical complexity | Simpler fixed structure, generally lower maintenance | Hydraulic detach system adds moving parts to maintain |
| Typical cost | More economical for standard hauling needs | Higher, due to the hydraulic gooseneck system |
If your equipment needs to be driven on from the ground rather than up rear ramps, our Removable Gooseneck (RGN) Trailer range is built for that. We'll be publishing a full lowboy-vs-RGN comparison guide in our Knowledge section soon — check back, or contact us now for a configuration recommendation.

A lowboy trailer (also called a lowbed trailer) is a heavy-haul semi-trailer with a deck built low to the ground between the front and rear axle groups. The low deck height keeps the overall load height down, allowing taller machinery to travel under bridges and power lines that would block a standard flatbed.
Lowboy, lowbed and low bed trailer are names for the same type of trailer. Lowboy is more common in North American usage; lowbed is more common internationally. Both refer to a heavy-haul semi-trailer with a low-height deck.
CHENLU lowboy trailers are available in 3-axle (30-60 ton) and 4-axle (60-100 ton) configurations. Exact capacity depends on axle count, axle rating, and configuration; heavier loads may require additional axles depending on local road weight limits.
A standard (fixed-gooseneck) lowboy is loaded from the rear via ramps. An RGN (removable gooseneck) trailer is a type of lowboy whose gooseneck detaches and lowers to the ground, allowing equipment to be driven on from the front — better suited to taller or lower-clearance machinery.
Yes — 3-axle or 4-axle, 13/16/20-ton axle ratings, mechanical or air suspension, and a choice of tire/rim specification, configured to your typical cargo weight.
Pricing depends on axle configuration, capacity, suspension type, and customization, so we confirm factory-direct pricing on inquiry rather than publishing a single fixed price. Share your cargo weight, dimensions, and destination country for an accurate quote.
Production is typically 10-30 days after deposit depending on trailer type and customization. Ocean transit time depends on the destination port and is confirmed at inquiry.
A lowboy tractor trailer is the combination of a tractor unit (truck head) and a lowboy semi-trailer. The tractor's fifth wheel couples to the trailer kingpin (2" or 3.5" on CHENLU lowboys), and the tractor pulls the low deck carrying the machinery. Match the tractor's power and fifth-wheel rating to the loaded weight of the trailer and cargo.
