For the rugged Australian conditions and maximum endurance, D’Angelo Engineering have designed
and patented the Maxi Heavy Duty range. With easy to use jaw adjustment and a two year structural
warranty the Maxi Heavy Duty fifth wheels are tough – and reliable.

The D’Angelo Maxi Heavy Duty range comes supplied with D’Angelo’s strongest jaw mechanism, giving you confidence that the load is secure, even on the toughest road conditions. The Maxi Heavy Duty is available with jaw sizes of 50mm, 75mm and 90mm. Together with its unique adjustable wear collar, the Maxi Heavy Duty also has a secondary retractable release handle. This means at all times, whether hooked up or disconnected, the handle retracts against the turntable. This feature reduces the likelihood that the release handle is unintentionally bent, which can cause problems when reconnecting.

The side mounted release handle and low profile design of the Maxi HD also means it suits slide-back type trailers.
