LionKar is the professional manufacturer of standard, RGN, extendable and heavy-duty lowbed trailers, our semi trailers are built with flexible capacities and configurations for construction, mining and oversized transport projects.
A lowbed semi trailer is a heavy-duty semi-trailer with a lowered loading deck, typically about 400–1,200 mm above the ground, designed to transport heavy, tall or oversized machinery. Depending on the design, lowbed trailers commonly use 2 to 8 axles or multi-axle configurations and can be built for payloads from about 20 to 150 tons or more.
Also known as a low bed trailer, low loader trailer or lowboy trailer, it may use a fixed gooseneck, detachable gooseneck (RGN), extendable deck or multi-axle structure. Compared with a standard flatbed semi trailer, its lower deck reduces overall transport height and lowers the cargo’s center of gravity, making it better suited to excavators, bulldozers, mining equipment, transformers and other heavy or oversized loads.
RGN / Detachable Gooseneck Lowboy
When selecting a low-bed semi-trailer, it is essential to comprehensively consider the cargo’s weight, dimensions (length, width, height), and shape characteristics, while also factoring in the actual transportation route and budget constraints to conduct an integrated evaluation for determining the most suitable vehicle configuration.
Some of the types are shown below. If you want to know more details, please contact us immediately.

Lionkar lowbed semi trailers’ frame strength and axle/suspension load distribution play an important roles, they directly support load capacity and road durability. Our lowbed semi trailers also use heavy-duty ramps, kingpins, landing gear, braking components and electrical parts selected for demanding transport conditions. During production, key assemblies are precisely fitted and welded, while the finished chassis is cleaned, sandblasted, primed and coated to improve corrosion resistance and long-term service life.
These specifications help the low loader frame resist bending, twisting and repeated impact when carrying excavators, mining machinery, transformers and other heavy equipment.
Main beam steel: high-strength steel
Main beam web: approx. 14–22 mm
Upper / lower flange plates: approx. 18–25 mm
Deck plate: approx. 5 mm checkered steel
Welding: automatic / submerged-arc welding for major load-bearing members
Reinforcement: additional cross members and local reinforcement available for concentrated loads
Axle quantity, suspension type and load distribution are matched to payload, cargo concentration and road conditions, helping reduce structural stress and improve durability on rough construction and mining roads.
Axle capacity: commonly 13T / 16T per axle
Axle configurations: 2–8 axles or multi-axle layouts
Heavy-duty leaf springs: commonly 90–120 mm wide
Brake system: dual-line air brake, WABCO or equivalent
Kingpin: 2″ / 3.5″
Landing gear: heavy-duty 28T class
In LionKar factory, we manufacture lowbed semi Trailer units for customers requiring practical cargo transport solutions. Our production covers trailer fabrication, structural configuration, technical specifications, component selection, and standard manufacturing processes for different cargo transport requirements.
As a professional China semi trailer manufacturer, our factory photos provide a closer look at the lowbed semi trailer structure, including the main frame, axle assembly, suspension system, landing gear, king pin, wheel components, surface finishing, and completed trailer details for overall product reference.
After delivery, lowbed semi trailer service may include follow-up support related to spare parts supply, component replacement, maintenance requirements, and technical information for standard trailer systems. This commonly involves axle assemblies, suspension parts, landing gear, king pin components, lighting systems, and fence structure accessories.
Lowbed semi trailers serve a wide range of transport tasks across construction, mining, energy and oversized-project logistics, with configurations adapted to different cargo, loading methods and operating conditions.
Excavator trailers, construction equipment trailers, machinery transport trailers and low loader trailers carry excavators, bulldozers, wheel loaders, graders, road rollers, pavers and cranes between jobsites. Low deck heights improve cargo clearance and transport stability.
Mining equipment trailers, heavy-duty lowbed trailers, multi-axle lowbed trailers and heavy haul trailers transport mining excavators, drilling rigs, crushers, screening equipment and large loaders. Reinforced frames and multi-axle layouts provide higher load capacity and better durability on rough mining roads.
Transformer trailers, heavy machinery trailers, industrial equipment trailers and modular trailers carry transformers, generators, turbines, tanks and large factory equipment. Reinforced load-bearing structures improve support for concentrated loads, while flexible axle configurations help distribute heavy weight.
Extendable lowbed trailers, telescopic trailers, wind turbine trailers, oversize load trailers and project cargo trailers transport steel structures, long beams, pipes, tanks and wind-turbine components. Extendable decks provide additional loading length and improve flexibility for over-dimensional cargo.

Lowbed semi trailers are usually shipped by Ro-Ro or bulk vessel, with container shipping available for smaller models. Before delivery, the frame, welds, axles, suspension, brakes, electrical system, ramps, tires and dimensions are inspected. Anti-corrosion wax/coating and waterproof covers protect the trailer from seawater and moisture. Typical lead time is 20–30 working days, depending on configuration and customization.
The following questions cover common topics related to Lowbed Semi Trailer structure, specifications, configuration options, and general product selection when comparing trailer requirements.
