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 8,400 pounds per caster. The series is rated for heavy-duty ground support and is built for greater stability due to their wide stance, drop-forged steel mounting plates and CNC-machined raceways. The wheels are available in six diameters and are equipped with 1- or 1¼-inch tapered roller bearings. Options include a permanently welded four-position swivel lock and a heavy-duty contact brake.
