SPMT is a kind of oversized engineering logistics equipment with its own driving unit, which provides engineering logistics solutions for the transportation of oversized, long and heavy cargoes that are not easy to be disassembled and transported as a whole, especially for the transportation of offshore oil rigs, offshore modules, modular factories (petrochemical smelting, etc.), power station construction, ro-ro loading and unloading of ships, chemical tanks, and the overall transportation of factory houses, etc. SPMT is mainly composed of a power head, which is also called a power unit (PPU), and a hydraulic trailer with a driving axle. The self-propelled hydraulic combination trailer consists mainly of a combination of a power head, also known as a power unit (PPU), and a hydraulic trailer with driven axles. According to the characteristics of the goods to be transported (external dimensions, tonnage, etc.), the end-user can carry out a multi-modal combination of multiple modular transport units, thus realizing the transportation of large tonnages and sizes of oversized parts over short and medium distances.
