The invention refers to a device for the transport of timber through a drying chamber (1) included in a timber-drying kiln, consisting of one or several transport units (6) guided on rails (8) and loaded with timber packages (4), which, through the influence of a driving unit move forwards through the drying chamber (1) and out through a discharge gate (2) arranged in connection with the drying chamber, which driving unit comprises a motion-transmitting oscillating movable drive element arranged to move parallel with the rails, which drive element is elongated and has one end located inside the drying chamber and a second end which via a transmission (17) is in a motion-transferring connection with a drive motor (15) located outside the drying chamber, by which the transport units are fed forward through the interaction with fingers (18) arranged along the drive element. To increase the total productivity of the drying kilns, the motion-transmitting drive element comprises a drive combination formed by two elongated separate drive components (9a, 9b) which, during the normal operation of the tunnel dryer, are separated from each other and located on the opposite sides of the discharge gate (2), where the ends of the respective drive components (9a, 9b) which meet and face each other are equipped with interacting gripping means (10) which, when the discharge gate is open, through the influence of adjustment means (11), can be adjusted into and out of a mutual interlocking grip so that the drive combination thus created is driven through the influence of the external drive part (9b), which via the transmission (17) is in a motion-transferring connection with the drive motor (15) located outside the drying chamber. |
