Imagine the challenge of moving a ship section weighing thousands of tons, a massive petrochemical reactor, or a several-hundred-ton power transformer. These behemoths cannot be disassembled, the path is constrained, and space is limited—conventional transport methods fall short. This is where the SPMT (Self-Propelled Modular Transporter) provides the ultimate solution.
An SPMT is far from an ordinary trailer; it is the engineering transport equivalent of a "Transformer" combined with a "precision instrument." Its core appeal lies in ultimate modularity and self-propulsion. Each SPMT unit acts as a powerful, independent drive module. They can be connected end-to-end and side-to-side, like building blocks, to freely create a transport platform of virtually any required size and axle configuration. Whether a project requires 4 axle lines or 40, needs to carry 100 tons or 10,000 tons, the system can be configured flexibly to meet the demand.
The Unity of Power and Agility
The "superpower" of the SPMT comes from its fully hydraulic drive system. Each wheel on every axle line can be controlled independently and with precision. This not only delivers astonishing load capacity (Huayan's SPMT single modules can carry up to 276 tons, with combinations handling thousands of tons) but also enables remarkable maneuverability. It can perform sideways crab steering, on-the-spot rotation, diagonal travel, and complex curved paths, navigating deftly through tight construction sites, shipyards, and factory premises to deliver colossal loads with millimeter accuracy.
Stable as Still Water, Control at Your Fingertips
When transporting such valuable cargo, stability and safety are paramount. The SPMT's advanced hydraulic suspension system automatically adjusts the height at each support point, keeping the platform perfectly level and absorbing road irregularities to ensure even load distribution. Operation has achieved intelligent leap: via wired or wireless remote control, the operator can command the entire synchronized fleet—moving, steering, lifting, and lowering—from a safe distance with centimeter-level precision, as if piloting a giant remote-controlled model.
Infinitely Customizable Solutions
At Huayan Vehicle, we understand that every major transport project is unique. Therefore, all our SPMT products and services are fully customizable. This goes beyond simply adding or removing modules; it's about tailored engineering from the ground up:
Load & Dimension Customization: We design the most economical axle configuration and platform layout based on your cargo's specific weight, dimensions, and shape.
Function Customization: Optional features like remote electronic synchronous systems, 360° steering, and drop deck configurations are available to meet specific needs such as transformer transport or large infrastructure projects.
Power Customization: Choose between diesel or electric Power Pack Units (PPU) to suit different environmental regulations and worksite conditions.
Compatibility Customization: Our core hydraulic systems are compatible with designs from leading international brands like Goldhofer and Scheuerle, ensuring interoperability with your existing equipment and spare part commonality.
From shipyards and bridges to wind power and petrochemical plants, from heavy machinery to aerospace facilities, Huayan SPMTs are tackling the impossible worldwide. Backed by a professional R&D team of over 60 engineers and built with top-tier components like Deutz engines and Rexroth hydraulic systems, every Huayan SPMT guarantees world-class reliability, durability, and safety.
