レーラドリーのターンテーブルロツク装置。 A turntable provided on a full-trailer dolly towed by a tractor and rotatably connected to the trailer body, a turntable lock mechanism that prohibits the turntable from rotating, and brake air that communicates from the tractor to the trailer. A first and second brake pressure switch is attached to the line and detects the air pressure in the line as a high pressure value and a low pressure value, respectively, and a brake pressure switch is attached near the driver's seat of the tractor and is used when driving on a road surface with a low coefficient of friction. When the jack knife prevention switch, which is turned on as appropriate, and the first brake pressure switch, or the second brake pressure switch in the on state of the jack knife prevention switch, respectively detect the corresponding predetermined air pressure values, the turn occurs. A turntable lock device for a full trailer dolly, characterized by comprising a lock controller for operating a table lock mechanism.
