Self-Propelled Modular Transporters (SPMT)
SPMTs are multi-axle, computer-controlled transporters capable of moving extremely heavy loads. They can be combined for virtually unlimited capacity.
Overview
Self-Propelled Modular Transporters (SPMTs) are hydraulic platform vehicles that can move extremely heavy and oversized cargo. Each SPMT module has multiple axles (typically 4 or 6) with independent steering and suspension, allowing precise maneuvering. Modules can be combined side-by-side and end-to-end to carry loads from hundreds to tens of thousands of tons. SPMTs are essential for module transportation, shipyard operations, and positioning heavy items.

Loading & Handling Tips
Frequently Asked Questions
How much can SPMTs carry?
Individual modules carry 120-360 tons depending on axle configuration. Combined configurations have moved over 15,000 tons. Practical limits depend on ground conditions and route constraints.
How fast do SPMTs travel?
Loaded SPMTs typically travel 1-3 km/h. Maximum speed unloaded is about 5 km/h. Moves are planned by hours and days, not minutes.
What powers SPMTs?
SPMTs are powered by Power Pack Units (PPUs) - mobile diesel/hydraulic generators that connect to the SPMT modules. Multiple PPUs may be needed for large configurations.
