Frequently asked questions
What is an SPMT?
An SPMT is a self-propelled modular transporter; its modules are coupled together to transport very heavy and bulky loads.
How is SPMT capacity determined?
The axle load series, the number of axles per module and the number of modules are determined by the weight and dimensions of the load and the bearing capacity of the ground.
Can it be used in Ro-Ro operations?
Yes. A configuration for Ro-Ro loading and unloading is prepared based on the ramp gradient and deck level data.
