Shock Absorbing Casters
Hamilton has patented its unique spring loaded design where the axle “floats” directly under the springs, as the wheel encounters obstacles. Shock absorbing casters reduce noise, protect cargo and extend caster, wheel and bearing life. Hamilton’s three series cover the most popular top plate sizes with five resilient tread wheel choices across six different diameters. Keep in mind that a spring loaded caster has a minimum capacity requirement for the spring action to work properly. Likewise, overloading a spring loaded caster will eliminate the shock absorbing benefit.
