    • Hamilton Dual Wheel Ground Support Casters

    Dual-Wheel Ground Support Casters

    Capacity Range: 2,000 – 8,400 lbs.

    Hamilton's 7700 Series is a line of dual-wheel solid pneumatic casters designed to cushion loads while providing a carrying capacity up to 8400 lbs. per caster. The series represents our highest rated caster series designed for heavy duty ground support and heavy manufacturing applications. The dual-wheel design essentially doubles the load capacity of Hamilton’s single wheel 7500 Series. These dual wheel casters also provide greater stability due to their much wider stance.

    All models have drop forged steel mounting plates and CNC machined raceways. The 16", 18", and 21" wheels are comprised of three tread sections: a firm, stable base compound for strong rim adhesion; a very resilient middle section to dampen the shock of uneven rolling surfaces; and a tough low rolling resistance tread to reduce energy consumption. The result is a soft ride that compares with full pneumatic tires, but with much higher capacities than their air-filled cousins.

    The 12" and 14" wheels are comprised of two tread sections. The same stable base found on the other wheels for strong rim adhesion combined with a tough abrasion resistant outer tread compound.
