Our fleet of modular and self-propelled trailers (SPMT)
From January 2023, Friderici Spécial will be adding Switzerland’s first self-propelled modular trailers to its fleet. Also known as SPMT (Self Propelled Modular Transporter), these self-propelled machine-carrying trailers are designed for transporting and lifting heavy loads that exceed the capacities of conventional trailers, semi-trailers or tippers.
Thanks to their sturdy galvanized steel chassis, advanced hydraulic system and motorized steering axles, they offer millimetre-accurate travel precision, and traction and braking capacity adapted to difficult terrain, even on slopes. Their exceptional manoeuvrability means they can operate in complete safety, even in confined spaces or on complex public works and industrial sites.
Modular self-propelled trailers: features and benefits
SPMT trailers are autonomous vehicles, equipped with a modular loading platform, hydraulic lifting system and powerful cylinders to adapt to the loads being transported. Unlike conventional trailers, they do not require a tractor-trailer or towing vehicle to move, offering unrivalled flexibility for the exceptional transport of oversized loads. Their mobility is ensured by a system of independent steering axles that allow infinite turning and adaptation to all types of terrain. They are designed for optimum traction, without the need to be towed by a truck, farm tractor or road tractor, facilitating rapid deployment on site.

In terms of safety, these trailers are equipped with reinforced lashing systems, securing hooks, stabilizing legs and adjustable loading ramps to ensure safe and efficient handling. With a payload of 256 tonnes per module, they can be combined to achieve a total capacity of 1,024 tonnes, meeting the requirements of large-scale construction sites.
Applications for self-propelled modular trailers (SPMT)
Self-propelled modular trailers are ideal for complex transport and lifting operations in many sectors. They are particularly well-suited to civil engineering work, especially for transporting prefabricated elements, beams, bridge structures and tunnel segments. They are also widely used in the industrial sector for transporting presses, heavy machinery and electrical transformers. The energy industry also benefits from their capabilities for conveying hydroelectric equipment, turbines, silos and technical infrastructures. Last but not least, they offer a modern, efficient alternative to machine-carrying trailers, car-carrying trailers, farm trailers and public works tippers for road haulage and specific handling.

Key features of SPMT trailers
Friderici Special’s self-propelled modular trailers are designed for optimum performance, flexibility and safety. Their galvanized steel chassis guarantees rugged strength, while their integrated hydraulic and elevator systems enable them to lift and move bulky loads with precision. They are equipped with motorized steering axles and heavy-duty tires, ensuring efficient traction on all types of terrain. Thanks to their radio-controlled operation, they can be positioned with extreme precision, even in restricted areas.
With a technical payload of 256 tonnes per module, these trailers can be combined to carry up to 1,024 tonnes total load, making them ideal for extreme transport and lifting operations. They are compatible with a variety of specialized equipment, including low-loaders, boat carriers, refrigerated trailers, flatbed trailers and utility trailers. Their safety is enhanced by high-performance brakes, secure tie-down systems, protective tarpaulins and non-slip loading ramps.








Why are our self-propelled modular trailers a first in Switzerland?
The arrival of these SPMT self-propelled trailers in Switzerland represents a major step forward in exceptional transport and lifting logistics. They reduce the need for towing vehicles, making logistics operations more efficient and safer. What’s more, they offer unrivalled precision for moving and lifting massive loads, thanks to their remote control and exceptional modularity. This technology also makes it possible to adapt trailer configurations to specific needs, combining several modules to achieve a record capacity of 1,024 tonnes.

In the press
Millepattes magazine highlighted this innovation with an article entitled “A Swiss first: 4 modules with 256 tonnes of payload!”, underlining the importance of this breakthrough in the exceptional transport sector.
