A vehicle is provided having a lift device comprising: a carrier; a swing arm with one end fixed to a shaft and another end coupled the carrier; and a drive for swinging the swing arm on top of the vehicle. The carrier is lowered from the top of the vehicle at an inclination with the point at which the carrier is attached to the swing arm raised. The swing arm comprises a first arm fixed to the shaft and a second arm mobile along the first arm that is coupled to the carrier. Telescoping means displace the second arm along the first arm when the swing arm swings, so that the carrier is retracted when the swing arm is upright. A support device supports the carrier, and support position displacement means cause it to project horizontally from the top of the vehicle when the carrier is lowered.
