<p>PURPOSE:To reduce the capacity of a driving source, by arranging a balance weight which is linked via a filament body to the connection part of the driving source and a frame body, is in the same weight as the total weight of the frame body, arm member and sheet fork body, and imparts a lifting force to the frame body, arm member and sheet fork body. CONSTITUTION:A driving source 23 vertically drives a frame body 7 in the state of a sheet 3 being suspended on a sheet fork body and the sheet 3 is carried into the specified position in a car body from the suspension position with a worker himself operating an arm member 11 directly with its turning movement in the horizontal direction. A roller 8 provided on this frame body 7 then is uniformly subjected to rolling contact on each face of the peripheral face of a column 6 to guide a smooth vertical movement without twisted of the frame body 7. A balance weight 28 is also in the same weight as the total weight of the frame body 7, arm member 11 and sheet fork body and imparts a lifting force for the frame body 7, arm member 11 and sheet fork body.</p> |
