Self-Propelled Modular Transporters (SPMTs)

Our Self-Propelled Modular Transporters (SPMTs) provide a game-changing ability to move heavy equipment through small entries and tight corridors. The pivoting wheel assemblies allow the trailer to move forward, backward and sideways. With a self-sufficient power source that eliminates power cords, the units can rotate 360 degrees without changing its midpoint. They fit where other trailers can’t!

American Cranes & Transport calls SPMTS “wheeled wonders.” Read the Article

SPMT Features

  • Modular Design

    • Simple trailer connections enable multiple configurations
    • Depending on the model, the trailers and hydraulic power units can be configured to a maximum of 4 trailers in 2 rows (4x2) or 6 trailers in 2 rows (6x2)

  • Wireless Control

    • A sophisticated wireless control system optimizes safety as the operator does not need to be on or in the transporter. Each self-leveling wheel unit has a steering and lifting cylinder that optimizes control and traction.

  • Equalized Suspension

    • The weight of the load is automatically spread across each of the connected trailers and wheels
    • The cylinders will absorb the unevenness of the ground and function to lift and level during travel

    • Two trailers and a power pack can be shipped inside a 20 ft. container

  • Hydraulic Power Units

    • One power pack can operate 2-3 trailers maximum depending on the model
