Fifth wheels are usually at a fairly standard height of around 1250mm, but this doesn’t suit all trailers and loads. This is where a dual height fifth wheel comes in handy. On the lowest setting, assuming the semitrailer is compatible, a fifth wheel might give 100mm or more extra headroom for a load. This could be the difference between a large piece of machinery being legal height or hejuru cyane.

A dual height fifth wheel is controlled from a panel that’s usually behind the cab. This activates air rams which push a mechanism to lift the fifth wheel. These systems are vulnerable to tampering, so it’s important that a driver checks the settings after returning to the lorry.

Pull the locking handle out to disengage the locking pin mechanism, or there may be a switch or button to control the locking – change this to unlocked.

If your fifth wheel has manual unlocking you may need to release a second stage lock and put the locking pins back into place – make sure they are all the way through and visible from the outside. If there’s a locking switch, activate it once you have finished. Then you can connect the trailer.
