Centerline 40T Rigid Neck Lowbed

The Centerline 40T Rigid Neck Lowbed is an incredibly strong, yet lightweight trailer that was designed with the city contractor in mind. It works great in water and sewer settings as well as subdivision development – basically any environment which requires a durable yet relatively small trailer.

Working Deck

40T Rigid Neck Lowbed


We use a short, narrow gooseneck with aluminum fenders. A staircase in the neck provides safe access to the lower deck.

A 10’ x 20’ working deck gives you plenty of loading space. Comes with 3” rough fir decking on outside area.

All fabricated QT100 mainframe design makes this trailer strong and able to handle heavy loads while keeping the tare weight down.
