SPMT Transport

Self-Propelled Modular Transporters • Abnormal Loads • Heavy Transport • Confined Spaces

Our fleet of hydraulic self-propelled modular transporters (SPMTs) are the ideal solution for manoeuvring cargo in confined spaces and intricately positioning loads.


The 360 degree manoeuvrability of SPMT trailers allows our team to undertake intricate positioning of abnormal loads and heavy cargoes in cramped or confined spaces safely delivering your cargo to its required destination. These platform vehicles regularly feature in our heavy transport operations providing an essential addition when undertaking the movement of transformers, vessels, tanks and industrial cargoes. The versatility of SPMT trailers allows them to be coupled in a variety of combinations allowing us to adapt our heavy transport services and directly tailor them to your cargo whilst their hydraulic capabilities provide the ideal solution for transporting heavy cargoes on gradients or inclines.

Our SPMT fleet is enhanced with the addition of our 4 axle Power Booster Module complete with power pack. Connecting module pack to any modular trailer combination allows us to effectively change the complete vehicle traction and pulling power capabilities, the equivalent to an additional ballast tractor being connected to the trailer.

Used predominantly for working on site, installations, portside positioning or RoRo operations our hydraulic self-propelled modular transporters offer a flexible alternative to more traditional transport methods. Coupled with our hydraulic jacking & skidding systems we can successfully undertake transport and positioning operations in sometimes tricky, more restricted environments.
