Apparatus adapted to be mounted on the bed of a towing vehicle for lifting and towing disabled vehicles, particularly large vehicles. The apparatus includes an extendible boom disposed for positioning beneath the disabled vehicle and retracted for moving the disabled vehicle close to the rear of the towing vehicle. The boom is pivotable about a substantially horizontal axis on an elevator from a vertically disposed storage position to its operative position, the elevator being slidably mounted in slideways for vertical movement between the storage position and the operative positions. The elevator is supported by an extendible beam which is vertically driven for raising and lowering the elevator and which is extendible for varying the angular inclination of the elevator which may pivot relative to the slideways.
