A self propelled transporter is a heavy-duty, hydraulically driven vehicle engineered for precise, self-propelled movement of oversized loads across shipyards, bridge construction sites, and industrial facilities. To accommodate different payload capacities and transport requirements, Aicrane provides two specialized solutions: Self-Propelled Modular Transporters (SPMT) for modular configuration and ultra-heavy load handling, and DCY Series Hydraulic Transporters for efficient heavy load transportation.
Self-Propelled Transporter Product Range
DCY Series Self Propelled Hydraulic Transporter
The DCY series hydraulic transporter is a self-propelled hydraulic platform vehicle designed for efficient heavy component transportation and industrial material handling. Combining a heavy-duty structural frame with an integrated hydraulic lifting system and multi-directional steering capability, the DCY series provides stable operation on industrial sites while functioning as both a heavy transport vehicle and a mobile work platform.
Integrated Heavy-Duty DesignThe optimized platform structure provides stable load distribution and high frame rigidity for continuous heavy-duty transportation operations.
Hydraulic Lifting and Suspension SystemHigh-stroke hydraulic cylinders allow independent chassis lifting and leveling, simplifying cargo positioning and improving transport stability without requiring additional lifting equipment.
Ground Adaptability and Flexible OperationEngineering rubber tires and balanced hydraulic suspension provide reliable movement across concrete, asphalt, compacted gravel, and hardened soil surfaces.
Self Propelled Modular Transporter (SPMT)
The Self Propelled Modular Transporter SPMT is a high-capacity heavy load transport system engineered for extreme payload handling and complex site maneuvering. Built with multiple axle modules, independent hydraulic suspension, and advanced electronic control systems, SPMT units can be combined side-by-side or end-to-end to create customized transport configurations for oversized and non-standard cargo.
Extreme Modular ScalabilityFlexible axle combinations enable customized transport configurations, supporting payload capacities from hundreds of tons to tens of thousands of tons through multi-module combinations for ultra-heavy projects.
Precision Electronic SynchronizationAdvanced multi-unit control systems ensure synchronized driving, steering, and load distribution across combined SPMT modules.
360° All-Direction ManeuverabilityMulti-mode steering enables precise positioning in confined job sites, including crab steering, diagonal movement, carousel rotation, and Ackermann steering modes.

Where Self-Propelled Transporters Are Used Across Heavy Industries
Self-propelled transporters are mainly used to move oversized and heavy loads in road and bridge construction, shipbuilding and offshore projects, energy infrastructure, and large industrial facilities. Typical cargo includes bridge girders, ship blocks, offshore modules, transformers, turbines, process equipment, and prefabricated structures.
Road & Bridge Construction
Major bridge, railway, and urban infrastructure projects require the movement of bridge girders, precast sections, steel structures, launching equipment, and heavy construction machinery between fabrication yards, storage areas, and construction sites.
Major project signals: Mega-span bridges, urban rail, highway, and port infrastructure.
Transport fit:
- DCY girder transporter is efficient for repeated girder and precast-component transport where payload and route conditions are relatively defined.
- SPMT is better suited to oversized bridge sections or assembled structures requiring flexible axle combinations, low-speed steering, and controlled positioning at the construction site.
Shipbuilding & Offshore Engineering
Shipyards and offshore fabrication facilities move hull blocks, decks, engine-room equipment, offshore modules, FPSO components, and large fabricated structures between workshops, assembly areas, storage yards, and quaysides.
Major project signals: Shipyard expansion, FPSO construction, offshore platforms, and offshore wind projects.
Transport fit:
- SPMT supports large ship sections and offshore modules through side-by-side or end-to-end module combinations, with steering modes suited to confined yard layouts.
- DCY is a practical choice for repeated movement of ship blocks, machinery, and other heavy components within established yard routes.
Energy & Power Infrastructure
Large energy projects require transportation of power transformers, turbines, generators, reactors, vessels, and prefabricated plant modules between manufacturing, staging, and installation areas.
Major project signals: Power plants, LNG facilities, renewable energy projects, substations, and grid infrastructure.
Transport fit:
- DCY is suitable for defined-capacity equipment and repeated plant logistics, with hydraulic lifting and steering supporting loading and positioning operations.
- SPMT is suitable for ultra-heavy or oversized equipment where multiple axle lines are needed to distribute load and adapt the transporter configuration to the cargo.
Petrochemical & Industrial Manufacturing
Industrial expansion projects involve the movement of process equipment, pressure vessels, production machinery, steel structures, and modular plant units from fabrication or receiving areas to installation locations.
Major project signals: Refineries, petrochemical complexes, heavy manufacturing plants, and modular industrial facilities.
Transport fit:
- DCY is suitable for recurring internal transportation of heavy equipment on prepared industrial routes.
- SPMT is better suited to large process modules, vessels, and high-payload project cargo where cargo dimensions or route geometry require customized configurations.
What Information Is Needed to Configure a Self-Propelled Transporter?
To configure a self propelled transporter, provide the cargo weight and dimensions, transport route, operating conditions, and loading method. These inputs determine the required capacity, axle configuration, platform dimensions, suspension, steering, power, and control systems.
- Cargo: Total weight, length, width, height, center of gravity, and support points
- Transport Route: Travel distance, road width, turning radius, gradients, ground conditions, and available clearance
- Operating Requirements: Transport frequency, required travel speed, steering modes, and positioning requirements
- Loading & Unloading: Loading method, loading height, required lifting stroke, and final positioning conditions
- Site Conditions: Indoor or outdoor operation, surface type, temperature, and other relevant environmental conditions
For SPMT transport systems, also provide the required cargo support arrangement and expected module configuration where known. For DCY hydraulic transporters, specify the target load capacity, platform dimensions, and operating conditions to identify the appropriate model.
The more complete the project information, the more accurately the self-propelled modular trailer or hydraulic transporter can be configured for the actual transportation task.
FAQs About Self-Propelled Transporters
What is a self propelled transporter?
What is an SPMT?
Is an SPMT the same as a self-propelled modular trailer?
No. An SPMT is a self-propelled module transport system with its own drive, steering, suspension, and control systems, while a conventional modular trailer requires an external tractor or towing vehicle.
SPMT is the standard technical term, although “SPMT trailer” and “self propelled modular trailer” are also used commercially.
