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! We have four models available to buy or rent. American Cranes & Transport calls SPMTS “wheeled wonders” and “rigging heroes.” Visit From the Headlines to view all of the recent articles featuring Engineered Rigging

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

  • Fast & Easy Delivery

    • 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
    • Tier-4 diesel engine for reduced emissions
