Air bearings for transporting heavy cargo

Using only 1/1000th of the power conventionally required, air bearing systems use air power to lift cargo weighing from several hundred to several thousand tons. Air bearings for heavy weight cargo and air porters for medium weight cargo are available from Kohan Kogyo. We sell units and also provide solution services to respond to all types of transportation problems.
Rolling chock removers for steel plants, which utilize the cushioning and low friction coefficient features of air bearings, are highly acclaimed for their cost and ease of use.

The strength of Japanese manufacturing. The world's best conveyors.
