Built for Heavy Distribution Transport

The TR steering arrangement is a mechanical system used primarily in heavy distribution transport. It steers one, two, or three axles on a one- to five-axle trailer, helping operators make more efficient use of their trailer through improved manoeuvrability in inner-city deliveries and on urban roads with small roundabouts.

Heavy distribution transport on one- to five-axle trailers
One to three steered axles using turntable mounting frames
Common on construction material, tippers, and tankers
Linear and progressive fifth wheel unit characteristics available
Optional gooseneck configuration (TR-V)
