Self Propelled Modular Transporter
SPMT: self propelled transporter, also known as a self-propelled modular trailer, which is mainly used for the transportation of heavy, huge, and special-shaped structures. The advantages of self propelled modular transporter are flexible use, convenient loading and unloading, and the load capacity can reach more than 50,000 tons under the condition of modules mechanical assembly or free combination. The self propelled transporter is widely used in manufacturing, petroleum, chemical industry, offshore engineering, bridge construction, and other engineering fields.
For mega engineering construction, the way of moving prefabricated segments and then transporting them to the site for general assembly is often adopted to effectively shorten the construction period and reduce the construction cost; If the modules are over disassembled, it is conducive to transportation and lifting, but not convenient to general assembly as well as commissioning. If the modular transporters are disassembled as little as possible, the single modules will be very huge but pose challenges on transportation and lifting. SPMT came into being under this demand.

WHAT AREAS CAN SELF PROPELLED TRANSPORTER TRAILER BE APPLIED FOR
Self-propelled modular transporter (SPMT) is mainly used for shipbuilding, petroleum, chemical industry, steel, and other engineering construction and equipment production. It has been used for medium, mega or heavy cargo transportation. According to different actual working conditions, different modules can be selected and combined into transport vehicles of various tonnage and forms to meet the needs of various working conditions. The modules can drive under the load bracket, lift the load with its jacking system, transfer it to any designated place and put down the load. This process does not require a crane or any other lifting equipment. The driving, lifting, and steering of the SPMT adopt the control and transmission form of "machine electric hydraulic" integration. The SPMT trailer is equipped with wireless remote control and a wireless emergency remote control, which has the same efficiency when driving forward or backward. Two or more modules can be combined and spliced, and one person can fully control the SPMT to complete different transportation tasks.
The product of SPMT manufacturers comply with relevant national standards and specifications with high rigidity, high seismic resistance, and high precision; Excellent cold and thermal stability; The electric control system has the properties of shockproof, antimagnetic, waterproof and high-temperature resistance, and can reliably complete the mobile transportation of hull sections or other heavy goods in ship construction and other engineering construction. The utility self propelled modular transporter for salehas the advantages of simple operation, convenient maintenance, and a beautiful appearance. The safety protection devices are complete and reliable, with perfect automatic protection and alarm functions.
HOW DOES SELF PROPELLED MODULAR TRANSPORTER WORK?
The first SPMT was born in 1983, designed and manufactured by Scheuerle, and delivered to Mammoet the next year. 30 years of running has not made them old. Now, these first SPMTs are still in service with Mammoet.
SPMT has made great progress since its birth. At present, the world's famous SPMTbrands include Scheuerle (Germany), kamag (Germany), Nicolas (France), Goldhofer (Germany), COMETTO (Italy), etc., mostly European brands (the first three belong to TII group); In recent years, Rui trailer has developed rapidly in this field which has greatly promoted the localization process of heavy cargo transportation in China.
As a pioneer, Scheuerle's SPMT has spread all over the world, with total usage of more than 5500 axes. It is widely used in shipbuilding, petrochemical, nuclear power, aerospace, road and bridge engineering, and other fields. Now it has developed to the fourth generation. Due to the adoption of welding robot technology, the load capacity of SPMT per axle has increased from 40 t of the third generation to 48 T, and the control technology has reached a new level.
SPMT modules have 2, 3, 4, and 6 axles specifications, among which 4 and 6 axles modules are the most common. The size design of SPMT is very particular. The module is 2.43 m wide, 5.6 m long (4-axle module), and 8.4 m long (6-axle module). It can be transported in standard 20 'and 40' containers. Some super mega engineering companies have a global business, but they may not have local branches, so it is necessary to transport the heavy equipment required for the project to the local. The transnational transfer of heavy equipment is generally a combination of ocean transportation and land transportation (highway and railway). The containerization of equipment can bring great convenience and save a lot of transportation costs, So as to achieve global rapid scheduling deployment, which was one of the original design objectives of SPMT.
Each axle line is composed of two pendulum axles. Each pendulum axle is equipped with two wheels (air-filled tire or solid tire can be selected). The center of the two wheels can swing at a certain angle along the center in the vertical direction, which can make the module compensate for the height of the ground in the transverse direction.
The most intuitive benefit of control technology is accurate and flexible steering control. No matter the number of modules or the complexity of the combination mode, it will not become an obstacle to steering. The unified management of computers makes all wheels cooperate seamlessly and can make almost any steering action.
In the case of a single module, several typical steering actions are as follows: the steering with the rotation center outside the module; 360 ° rotation in place; Lateral driving; Drive diagonally. In the case of multi-module combination, the steering action is also flexible, for example, the T-type combination turns around the external rotation center; The ring combination rotates around the center or translates around.
