A tractor adapted to be connected to a semi-trailer is provided and includes a chassis having at the rear end portion a fifth wheel and behind that a pick up ramp arranged to guide the trailer in position so that a king pin on the trailer can enter an opening in the fifth wheel when the tractor is driven in reverse towards the trailer. The pick up ramp is moveable by power means between an upper tilted pick up position and a lower storage and driving position in which the ramp rests on beams of the chassis.
