A self-propelled modular transporter or sometimes self-propelled modular trailer (SPMT) is a platform heavy hauler with a large array of wheels which is an upgraded version of a hydraulic modular trailer.

This Best Practice Guide for the use of SPMT´s is the result of the joined effort of different global stakeholders in the world of self-propelled modular transporters. The document has been composed under the guidance of the European association of …

HYDRAULIC POWER The SPMT is propelled by hydraulic drive motors, which are mounted on the axles of the SPMT. Hydraulic power is supplied from a pump on the power pack to each of the drive motors and speed is controlled via a remote hand operated portable console. Forward and reverse travel is achieved by

SPMTs have the possibility of 360-degree steering of the wheels. This allows carrousel and sideway movements. Their deck height can hydraulically be adjusted by approximately 60 cm., enabling vertical lifting or lowering of the load. Due to their variety of combinations, SPMTs can lift and move virtually every heavy load.

Jun 27, 2017 · Self-propelled modular transporters (SPMTs) are used for rapid removal and installation of bridge systems.

Mar 1, 2021 · Self-propelled modular transporters (SPMT) are platform vehicles used to move heavy loads on-site – typically during construction and maintenance projects. The SMPT is especially useful wherever there’s no access for a crane or truck.

• Hydraulic axle compensation, hydraulic lifting device of the platform • Pipe- and protection system in one circuit design in the hydraulic support system • Each support cylinder can be removed from the system by a shut-off valve (ball valve) with help of an axle

Feb 13, 2025 · The SPMTs use a hydraulic system that controls various functions including driving, lifting, cooling, braking, and steering. Other major components include the steel frame, the electronic system, and the power pack unit. An SPMT can use either an electronic or a mechanical steering system.

Feb 13, 2025 · The SPMT comes with a Power Pack Unit (PPU) and axle line modular unit. The modular unit has a hydraulic suspension, which is available in three types: wheel bogies-drive, wheel bogies-idle and wheel bogies-braked.

In such cases, Mammoet’s Self Propelled Modular Transporters – or SPMTs - are a reliable, safe and efficient transport option. SPMTs are compact platform vehicles that can be used to move heavy loads. They are modular and the units can be connected for a higher cumulative capacity.
