SPMT Self-Propelled Modular Transporter is a new way to transport heavy components. German TII group has set a world record of transporting 15000 tons of oil platform with this device, and the error is only 2 mm. China is in the ascendant in this field.
SPMT Self-Propelled Modular Transporter is generally driven by hydraulic or electric power and can move along more than two axes. Multiple vehicles can be combined to carry larger modules. At first, this kind of vehicle was developed for the aerospace field, and then gradually used in various large-scale engineering construction and shipbuilding industries. SPMT Self-Propelled Modular Transporter was first used in the field of space launch. NASA of the United States began to use German kmag SPMT Self-Propelled Modular Transporter to carry American rockets as early as 1979. China has also used a variety of similar vehicles in the field of space launches. The application of SPMT Self-Propelled Modular Transporter in shipbuilding is a new technology in recent years. The new aircraft carriers of Britain and America both use SPMT Self-Propelled Modular Transporter to carry parts of the aircraft carrier.

China began to study SPMT Self-Propelled Modular Transporter in the 1980s, but in the field of manufacturing and engineering construction, it is still unable to compete with the established companies in Britain, Germany and other countries.
The famous SPMT Self-Propelled Modular Transporter brands in the world mainly include Scheuerle, Goldhofer and COMETTO.
The main engineering construction company in the world is British ale, which has all the design and construction capacity, and also has the largest number of SPMT Self-Propelled Modular Transporter in the world. Other international super large cargo transportation companies are mammeet (Holland), sarens (Belgium).
The speed of SPMT is 1-5km / h and the axle load is 30-50t.
how to choose self-propelled modular transporter manufacturers
Different from the large tonnage SPMT Self-Propelled Modular Transporter launched by many manufacturers, the latest customized spmt600 launched by Enerpac is a light SPMT Self-Propelled Modular Transporter with 3 axes for each module. Each module carries 60 tons (20 tons of axle load). It is easy to operate and the operator can master the use method in one day.
TII group is a diversified development direction. Its new products include SL model's transverse splicing 3-column model, AC model's model that can adapt to the polar temperature environment, ES model's large tonnage model with a load of 60 tons per axis, f model's high-speed model with a driving speed of 22 kilometers per hour, and the electric driven SPMT self-propelled hydraulic combined Trailer with good operation performance.
Scheuerle has also done a lot of work on the handling of the vehicle. At the same time, they also provide products under all road, different weather conditions and specific transportation conditions. They believe that the diversity of products is the key factor for their future success in the market competition. Recently, ale and Scheuerle signed a 240 axis order, which shows their leading position in their respective industries.
At present, each manufacturer has its own large tonnage SPMT Self-Propelled Modular Transporter, and the loading capacity of 60 tons per axis is the highest SPMT Self-Propelled Modular Transporter in the world. At the same time, the 60 ton power module also has higher bending moment, which enables it to undertake the transportation of larger tonnage goods. As high tonnage SPMT Self-Propelled Modular Transporter has the same high requirements for pavement, the 60 ton SPMT Self-Propelled Modular Transporter purchased by ale is mainly used in developed countries such as the UK and the Netherlands. Scheuerle said that it was its catering to ale's demand for high tonnage SPMT Self-Propelled Modular Transporter that led to the large order of 240 axis.
Mammoet also purchased many SPMT Self-Propelled Modular Transporter in Scheuerle, including AC series SPMT Self-Propelled Modular Transporter which can operate normally under polar conditions. This kind of SPMT Self-Propelled Modular Transporter is equipped with hybrid rubber sealing ring which can adapt to low temperature environment, auxiliary power station for engine to maintain temperature, and hydraulic oil antifreeze to ensure its normal flow in low temperature environment. Because the polar environment usually requires long-time lighting, its lighting lamps are also replaced by LED energy-saving lamps.
In the aspect of engineering logistics, the general trend is that the size of goods is getting bigger and bigger, the weight is getting heavier and heavier, the size of modules is getting bigger and bigger, and the center of gravity is getting higher and higher, so a wider SPMT Self-Propelled Modular Transporter is needed to carry the modules with high center of gravity. So Scheuerle developed SL model to make SPMT Self-Propelled Modular Transporter horizontal to increase width.
(also known as SMPT). It is mainly used for the transportation of heavy, large, high and special-shaped structures. Its main advantages are flexible use, convenient loading and unloading, and its carrying capacity can reach more than 50000 tons in the case of multi vehicle mechanical assembly or free combination. It is widely used in equipment manufacturing industry, petroleum, chemical industry, offshore oil, bridge construction and other engineering fields.
