The new series represents its highest rated caster series designed for heavy duty ground support and heavy manufacturing applications over rough surfaces.  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.   
 
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 16", 18", and 21" wheels are comprised of three tread sections: a firm, stable rubber 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.
 
The new 7700 Caster Series can be optioned with permanently welded four position swivel lock and a heavy duty contact brake.  The new series is backed by Hamilton’s industry-first three year product warranty.
