A system for immobilizing a semi-trailer kingpin on a transport vehicle includes a balance arm and a substantially horizontal rigid linking structure designed to guide the vertical movement of the receiving nacelle, hold it in position above the lifting system in a horizontal plane and take up the forces exerted thereon. The longitudinal rigid linking structure is hingedly linked to the receiving nacelle and to the transport vehicle in order to take up the longitudinal forces from same, and the balance arm includes preloaded springs that take up the forces exerted on the balance arm when the receiving nacelle is temporarily inclined relative to the horizontal plane. The lifting system for lifting the receiving nacelle is mounted pivoting on the railway unit at a pivot pin transverse to the longitudinal axis of the transport vehicle.
