Our hydraulic modular trailer is designed to carry oversized and super‑heavy cargoes that standard semi‑trailers cannot handle.
A hydraulic modular trailer (HMT), also referred to as modular trailer in heavy‑haul industry, is a specialized multi‑axle heavy‑duty transport unit designed to carry oversized and super‑heavy cargoes that standard semi‑trailers cannot handle.
Modules can be combined in length or width to carry oversized & super‑heavy cargo. With hydraulic suspension and independent steering, it maintains load stability on rough African roads for wind power, mining, petrochemical and bridge project cargo. It is tractor‑pulled, different from the self‑propelled SPMT.
Our specifications below represent typical LionKar hydraulic modular trailer configurations. The suitable configuration depends on cargo type, payload requirements, road conditions and local regulations.

Lionkar, China hydraulic modular trailer manufacturer, delivers modular units with reliable hydraulic system, anti‑torsion structure, high‑strength steel frame and heavy‑duty hydraulic suspension, ideal for ultra‑heavy payloads, oversized cargo and harsh road conditions.
Constructed from Q690 high‑tensile steel, our hydraulic modular trailer units feature precision‑welded anti‑torsion frames with non‑destructive weld inspection. Each axle line is rated for 36‑45 tons, with ±300 mm suspension travel and 55° steering angle. Optimized for modular combination, the robust chassis resists bending and torsion under extreme heavy‑load conditions, validated by factory load‑simulation tests for reliable operation.
These features help prevent frame deformation when driving on rough roads and minimize the risk of structural failure during the transport of ultra-heavy loads.
Our hydraulic modular trailers are fitted with environment‑optimized key components tailored for African operating conditions.
By adding a Power Pack Unit (PPU) to an HMT module, it becomes an SPMT (Self-Propelled Modular Transporter).
| Features | HMT (Hydraulic Modular Trailer) | SPMT (Self-Propelled Modular Transporter) |
| Power Resources | No self-propulsion | Self-contained power unit (PPU) |
| Drive method | Passive traction | Self-driven |
| Typical configuration | Vehicle platform + hydraulic system | Vehicle platform + Hydraulic system + PPU |
| Flexibility | Relies on external traction equipment | Capable of independent operation |
At LionKar factory, we produce hydraulic modular trailer units for customers seeking reliable transport solutions for oversized and super‑heavy cargo. Featuring combinable modular architecture and independent hydraulic suspension, our production scope includes unit fabrication, modular configuration, technical specification design, component selection, and standardized manufacturing workflows to meet diverse heavy‑haul project demands.
With 17 years of industry experience and an annual export volume of over 2,500 semi-trailers to Africa, we are deeply rooted in the African infrastructure transport market, providing local customers with stable, reliable heavy-duty transport equipment and comprehensive after-sales support.
As a professional Chinese manufacturer of hydraulic modular trailers, our factory photos display the construction of our units, including main frames, cargo platforms, axle assemblies, wheel components, surface finishing and fine details for your complete reference.
After delivery, our hydraulic modular trailer full after-sales service covers comprehensive follow-up support, including original spare parts supply, professional component replacement, on-site maintenance guidance and complete technical documentation for trailer hydraulic and modular systems. Key available spare parts include axle assemblies, hydraulic suspension parts, hydraulic cylinders, steering system components, braking system parts, electrical systems, modular connection accessories and structural frame fittings.
A hydraulic modular trailer is a heavy-duty transport solution for oversized and super-heavy cargo. Its modular units can be combined to create a platform that matches the exact size and weight of each load.
Wind energy equipment transport trailers are used to transport wind turbine blades, nacelles, tower sections, large transformers, and generator units for wind farm and power plant construction.
Heavy haul trailers are used to transport reactors, pressure vessels, large storage tanks, mining crushers, and other heavy-duty industrial equipment.
Oversize transport trailer carry pre‑cast bridge segments, steel girders, concrete modules and heavy construction machinery for road and bridge projects.
Oversize load trailers are used to deliver port machinery, ship sections, large steel structures, and other non‑standard oversized goods.
Tell us about your cargo types, operating conditions, and preferred specifications, and we’ll work with you to develop a hydraulic modular trailer tailored to your transport requirements.
Backed by decades of heavy-duty trailer manufacturing experience, we offer both standard series and fully customized configurations to meet your specific transport needs.
Feedback may be shared at different stages of a project, including factory visits, product discussions, inspections, and completed deliveries. Together, these experiences reflect different aspects of customer interaction with Lionkar, covering hydraulic multi axle trailer and other commercial trailer projects.
Our hydraulic modular trailers are well‑received by customers across Africa, including Nigeria, Ghana and Angola. We believe transparent production processes are key to earning clients’ trust.

Every hydraulic modular trailer unit undergoes strict full‑scope factory inspection before delivery, including hydraulic system, welding quality, braking system, electrical system and dimensional accuracy. Anti‑rust treatment and secure lashing are done for sea transport. Trailers can be shipped to Africa by Ro-Ro, bulk vessel, container, or flat rack, with anti-rust protection and secure fastening. Typical transit times are about 25–35 days to East Africa, 25–40 days to Southern Africa, and 35–50 days to West Africa, depending on port and vessel schedule.
The following covers the most common questions from customers purchasing hydraulic modular trailers, with detailed answers to key concerns.
Our hydraulic modular trailer is engineered for harsh off‑road conditions. The independent hydraulic suspension absorbs road shocks, distributes load evenly, and delivers good performance on gravel and unpaved roads.
We offer 2, 3, 4 and 6 axle-line series, and can build custom configurations to meet higher payload or special dimension requirements. Each axle line features independent hydraulic suspension for even load distribution.
A low-bed semi-trailer is a fixed structure for common heavy loads, while a hydraulic modular trailer is composed of multiple combinable units with hydraulic suspension, enabling larger, heavier and more flexible transport that a single semi-trailer cannot handle.
Our modular trailers use stable load beds, independent hydraulic suspension, multi-axle steering and reliable braking systems to keep cargo stable. We also provide transport planning and load securing guidance for each project.
Yes. Axle lines, platform width and length, suspension type and accessories can all be customized to your load dimensions, weight and transport route.
Delivery time depends on configuration and quantity; we will confirm a clear schedule after receiving your specifications. We offer spare parts supply, technical support and after-sales service for long-term operation.
Contact our engineers with your cargo weight, dimensions and transport route. We will recommend the right axle-line configuration and provide a free transport solution.
