New Casters for Uneven Surfaces

Hamilton Caster, Hamilton, Ohio, has launched the new 7500 caster series for carrying heavy loads over uneven surfaces. Constructed with Hamilton’s trademark premium forged steel design and heavy duty, semi-pneumatic tires, the casters offer twice the load capacity of a traditional pneumatic caster, it said.

They deliver a smooth ride—even over rough or broken concrete—that makes them ideal for ground support equipment in the aircraft and aerospace industries, construction, outdoor uses, and shock protection for heavy loads.

The 7500 series is available in six wheel sizes ranging from 10 to 21inch diameters with load capacities ranging from 1,000 to 4,200 pounds per caster. The caster is also offered in a dual-wheel version which doubles the caster’s total load capacity.

The tires are engineered with three tread sections: a firm, stable base compound for strong rim adhesion; a 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 higher capacities.
