Abstract: A heavy door open and close system is provided using a pneumatic cylinder utilizing on board vehicle air. The system includes a hydraulic cylinder which is adapted to lock the door in either an open or closed position. A manual activation system uses a hydraulic valve to unlock the hydraulic cylinder and a pneumatic valve to actuate the pneumatic cylinder to open or close the door. An emergency pneumatic actuation system is also provided for use when the system loses the use of on board air of the vehicle.
