SYSTEM FOR INSPECTING AND/OR TREATING LARGE SURFACES

The present invention relates to a system (1, 100) for inspecting and/or treating a surface which substantially extends on a plane being parallel to a X-Y plane. The system (1, 100) comprises: mobile means (8; 101, 102, 103, 104) which is movable according to a second axis (Y); a first mobile first side pulley (9) and a second mobile first side pulley (10) which are connected with said mobile means (8; 101, 102, 103, 104) and placed in said X-Y plane at a first side of said mobile means (8; 101, 102, 103, 104); a first mobile second side pulley (1 1 ) and a second mobile second side pulley (12) which are connected with said mobile means (8; 101, 102, 103, 104) and placed in said X-Y plane at a second side of said mobile means (8; 101, 102, 103, 104); a first fixed first side pulley (2), a second fixed first side pulley (3), a third fixed first side pulley (4) and a fourth fixed first side pulley (5) placed in said X-Y plane at said first side; a first fixed second side pulley (6) and a second fixed second side pulley (7) which are placed in said X-Y plane at said second side; a carrier (13) for transporting at least one inspecting device and/or said at least one treating device, wherein said carrier (13) is movable according to a first axis (X); a first cable (14) which is connected with said carrier (13) and sequentially wound on the second mobile first side pulley (10), the third fixed first side pulley (4), the second fixed first side pulley (3), the first fixed second side pulley (6), the first mobile second side pulley (1 1 ) such as to form a first closed loop; a second cable (15) which is connected with said carrier (13) and sequentially wound on the second mobile second side pulley (12), the second fixed second side pulley (7), the fourth fixed first side pulley (5), the first fixed first side pulley (2), the first mobile first side pulley (9) such as to form a second closed loop; first motor means for making said first cable (14) move in one direction or in the opposite direction; and second motor means for making said second cable (15) move in one direction or in the opposite direction; wherein the first fixed first side pulley (2), the third fixed first side pulley (4), the first mobile first side pulley (9), the second mobile first side pulley (10), the first fixed second side pulley (6), the second fixed second side pulley (7), the first mobile second side pulley (1 1 ) and the second mobile second side pulley (12) are placed such that said fi
