PURPOSE:To obtain the remote operation of a gear control lever in a transmission device by constructing an operation lever on a work table to be linked with an operation member on the side of a propelling bogie via a chain transmission mechanism. CONSTITUTION:For obtaining the power transmission from a work table 3 to a self-propelling bogie 1, an expansion link mechanism 2 is provided with a chain transmission mechanism 43, and a drive sprocket 45 with an operation lever 44 in one body on the boss is equipped on an axis 23 on the side of a guide rail 22 stretched on the work table 3. This construction permits to disuse an operator on the ground, since the lifting operation of the operation table 3 and various operations of the self-propelling bogie 3 can be all done on the work table 3 as well. |
