Hamilton’s 7700 Caster 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. These casters also provide greater stability due to their wider stance. All models have drop forged steel mounting plates and CNC machined raceways. Available in six wheel diameters from 10" x 4" to 21" x 6", all wheels are equipped with 1" or 1 1/4" precision tapered roller bearings making them well suited for power-towed applications. The 7700 Caster Series can be optioned with permanently welded four position swivel lock and a heavy duty contact brake. The series is backed by Hamilton’s three-year product warranty.
