Capacity Ratings
The caster and wheel capacities shown on this site are based on the following conditions or have been established through industry standards and accepted usage.
General Conditions
All ratings are based on operation over smooth floors, rails or tracks with no obstructions or severe shock loads. All bearings must be properly lubricated. Conditions of excessive temperature, excessive dirt, or other contaminants will reduce capacity and will minimize performance. Capacity ratings cannot be used when the product is misapplied or modified.
Manual Operation
Manual operation capacities apply to non-powered movement of loads only.
Power Operation
Tractor drawn, mechanically moved conveyer or tow line require specifically designed casters to withstand conditions encountered in these mechanically powered operations. Consult Colson's Engineering Department for specific recommendations concerning your particular application.
All casters and wheels are rated up to 2.5 mph operation per the Institute of Caster & Wheel Manufacturers Guidelines.
