This invention regards to a ceiling movable disused car scrapping system, more specifically, the invention is capable of to adjust the height and to move left and right hand side by itself at its position, and, as it mounts the disused car, it is capable of adjusting the disused car height and rotating, and adjusting the disused car location. Thus it can scrape the disused car at its position as a one-stop disused car scrapping system.The invention consisted of a rail transfer unit (10) which includes rail pulley (14) installed at the ceiling rail (11); an up-and-down transfer unit (20), of which extension length was adjusted by a cylinder actuator (24) of a up-and-down cylinder (23) of an up-and-down boom (22), which is installed at inside of a fixed boom (21) that was connected to the rail pulley (14) in a vertical direction; a boom operation unit (50) which includes a movable boom (52), which was installed at inside of a boom (51) connected at the bottom of the up-and-down boom (22), connected by a cylinder actuator of an operation cylinder (53); an upright unit (40), which connects an upright column (41), extended from the movable boom (52), to the top of a stack column (62) and connects a cylinder actuator (44) of an upright cylinder (42) that is connected to the movable boom (52) to a upright reinforcing bar (43); and a disused car fasten unit (60) which includes a stack base (61), installed at bottom of the stack column (62), to support the disused car and a push bar (66) with a push plate (67), which is installed at a push column (65) extended from the stack column (62), connected to a cylinder actuator (64a) of a push cylinder (64).
