    "The 99,000 lbs/tire Dolly"

    Modular Aircraft Tarmac Dollies

    (12,000 to 99,000 lbs/tire)

    (Up to 247,000 lb Aircraft)

    Modular Aircraft Tarmac Dollies (MATD) consit of four Tri60 with four Tri-Bars forming a solid square dolly.
    Tarmac surfaces are grooved for rain run off. This surface create challenges for most casters, which is resolved with double wheels and wider wheels.
    Double wheels maintain the caster capacity, while
    Wider Wheels reduce vibration and extend caster life
    Speed down a long runways is always priority 1, so
    Diameter (or should say π r ²) is king. A 12" caster is 5.76 times faster than a 5" casters.
    We offer 20 MATD in 5 diameter sizes:
    • 5" - 12,000 lbs/tire (30,000 lb Aircraft)
    • 6" - 60,000 lbs/tire (150,000 lb Aircraft)
