A series of advanced technologies in our Self Propelled Modular Transporter (SPMT). For example the electronic driving system, lifting system and all-wheel independent steering, hydraulic leveling frame and 3/4 points support technologies.
It can realize carpooling transport load. Besides, through CAN bus connection microprocessor controlled unit, SPMT can realized driving, lifting and steering.
Application areas like shipbuilding, petrochemical as well as other fields.

of Our SPMT,
01、New frame construction
Through finite element analysis(FEA), the frame structure design and manufacturing process were optimized. And 6.7 tons of lifting lugs were added on both sides.
The rigidity of the frame is close to Germany Scheuerle. In the case of two-point concentrated load (full load), the deformation of the frame is 16mm greater than that of the German Scheuerle.
02、Split steering mechanism
With original split steering mechanism, it shorten the whole manufacturing cycle of SPMT.
On the one hand it ensures the reliability of steering mechanism, on the other hand solve the problem of steering mechanism's quick repairing. Unlike scheuerle SPMT can not make it due to the deformation of box body.
03、Same quick coupling model and layout
Brand, specification, quantity and layout of hydraulic quick couplings are totally same as Scheuerle SPMT.
Electrical harness is same with Scheuerle.
04、Lift proportional valve set with three-stage safety valve
FIRST manufacturer who uses lift proportional valve set with three-stage safety valve in China.
Equipped with integrated type hydraulic lock, the main oil circuit cut-off valve, hydraulic lock control oil cut-off valve. Thus it makes the lifting operation safer and more stable.
05、Enhanced hydraulic tank
Owing to strengthened structure, the hydraulic tank will not damaged easily.
Increasing the hydraulic tank volume, thus one PPU can drive 40 axles SPMT.
Adding oil suction filter, hydraulic oil impurities dropped, as well as improve the life of hydraulic components.
06、Open pump pressure distribution system
For the open pump, there are 4 different pressure control, 200bar, 280bar, 310bar, 360bar e.g.
Open pump pressure distribution system can distribute the pressure rationally of the support system, steering system and brake system. What’s more the pressure of each hydraulic system does not interfere.
07、Walking buffering system
The walking buffering system of the SPMT can effectively reduce the damage to the walking motor caused by high speed brake.
08、Optional filled tires
First pneumatic tire filling process in China, the filling material is same as Scheuerle.
While load about 12.5 tons, the subsidence of tire 43.2mm is close to Scheuerle SPMT .
Max Cargo weight
