In building, repairing and refurbishing mobile equipment, such as trucks, benches, tables, etc., various effective combinations may be used. Several types of mountings are illustrated below.

                   Three Swivel. For barrel dollies and small portable machines. Affords excellent 
                maneuverability. Be sure to select casters designed to take the weight load on 
             three casters rather than the usual four.

                  Two Rigid, Two Swivel. Most practical and inexpensive arrangement for straight 
                   and/or long distances. Can be used for heavy or medium loads, depending upon the 
                   weight capacity casters selected.

                  Tilt Mounting. A tilt mounting is the most economical, but should be limited to 
                  lighter loads. The tilt is best when the load wheels are 1/8" taller (over all 
                  height) than the balance wheels. Not recommended for use on ramps.
