SPMT is known as self-propelled modular transporter. It is a kind of hydraulic platform trailerequipped with a powered diesel engine or an electric motor to drive itself to move, lift and steer, no need for involvement of tractor or prime mover.

SPMT is known as self-propelled modular transporter. It is a kind of hydraulic platform trailer equipped with a powered diesel engine or an electric motor to drive itself to move, lift and steer, no need for involvement of tractor or prime mover.

Electric SPMT with lithium battery is our newest generation of SPMT, which is a green power vehicle and easy to transform to AGV(Automatic Guided Vehicle).

Self-propelled modular transporter is widely used as a perfect solution to transport modules such as oil platform rigs, factory modules, chemistry vessels, nuclear reaction tower, harbor crane in shipbuilding, high-speed railway bridge construction, windmill construction, offshore modules (load-in/out), harbor logistics, and other engineering logistic projects. Industries like construction, chemical engineering, refinery, metallurgy, ocean engineering, conventional energy (oil and gas), and eco-energy all have an increasing demand for SPMT.

The full name of SPT is self-propelled transporter, without the word modular compare the SPMT.
SPT belongs to SPMT. It is an easy version of SPMT. In general, we also call SPT SPMT.
SPT is evolved from hydraulic modular trailers. It mainly consists of three parts: ordinary hydraulic multi-axle trailer, power head PPU, and the drive axle module.
The appearance of SPT and SPMT is the same. Both consist of PPU and trailer module. From the appearance, it’s hard to tell whether they are SPT or SPMT.


Different steering modes
  • SPT is controlled by the linkage rods. It is a kind of overall steering mode.
  • The SPMT is controlled by a worm and gear or a rack and pinion, with each suspension steering independently.
The steering angle is different
  • The steering angle of SPT is usually between 45 degrees and 55 degrees, and the steering mode is only one.
  • The steering angle of SPMT can reach more than 90 degrees and realize a variety of steering modes, such as crosswalks, which can make the vehicle movement more efficiently in a smaller range.
SPMT is more versatile

SPMT transport has a wider universality, due the SPMT has tires (rubber tires, PU tires or polyfill tires), can move on various roads, even sand gravel road, side road, and inclined road. The working site no need paved with rails or slide rails and other facilities.

Traditional rail transport needs a concrete road mounted with rail. Investment on the paved road and rail is high. The advantage of rail transport way is: cost to use is lower than the SPMT transport method.

With the help of SPMT, the manufacturing plants of big projects and storage yards are not limited to specified places. More application cases are using SPMT instead of rail transport in petroleum, electric power, metallurgy, chemical industry, construction, high-speed railway construction, shipbuilding, new energy (wind and solar power), nuclear power and other industries.

Under normal conditions, traditional rail transport can not run on the ground with a big slope, which means you have to make up the slope gradient before using the traditional rail transport method.

Lifting function

If we put the cargo on a bolster holder, the SPMT is able to enter into the holder directly, then start moving after raised to lift the holder from the ground. After arriving at the destination, the SPMT platform is lowered, and the holder with the cargo is placed in the yard or the assembly site. With the help of the bolster holder and lifting function, the self-propelled modular transporter can realize self-loading and unload automatically.

Most rail cars have no lifting functions.

Combination function

The rail equipment can only transport the cargo within a single vehicle and cannot be combined to transport oversized one. During the transportation of oversize cargo, we can combine several modules of SPMT and connect the hydraulic pipeline and circuit to realize the synchronous operation of multiple SPMTs, so as to meet the requirements and ensure safety.
