A compensator for a fifth-wheel coupling is disclosed. The compensator comprises mounting structure for connecting the compensator to a towing vehicle unit, a first support comprising a first mounting pivot and a first coupling pivot, and a second support comprising a second mounting pivot and a second coupling pivot. The mounting pivots are each pivotally connected to the mounting structure. The coupling pivots are each pivotally connected to the fifth-wheel coupling. The compensator further comprises a limit assembly configured to restrict movement of the supports by (i) engaging with the support between the mounting pivot and the coupling pivot; or (ii) engaging with the coupling pivot. A first axis extends through the first mounting pivot and the first coupling pivot, and a second axis extends through the second mounting pivot and the second coupling pivot. In use, the first and second supports are pivotally connected to the fifth-wheel coupling to support and allow movement of the fifth-wheel coupling relative to the mounting structure. In use, an intersection of the first and second axes defines a roll centre about which the fifth-wheel coupling moves relative to the mounting structure. In use, the first and second supports are aligned respective to each other such that the fifth-wheel coupling is positioned between the roll centre and the mounting structure.
