Abstract
A vehicle timber bank arrangement having a horizontal supporting beam and generally vertical post assemblies mounted at respective ends of the beam. Each post assembly includes a bottom post anchored firmly to the beam, and at least one top post which is displaceable telescopically to its associated bottom post. A pivotal upper connection member is pivotally mounted at at least the first top post, and at the second top post there is mounted a device for coupling with the upper connection member when this device is in a position in which it connects or binds the two to posts. The upper connection member is swung by a piston-cylinder device which functions to displace the first top post telescopically in relation to the first bottom post. The first top post and the part of the piston-cylinder device which actuates the first top post are coupled together by a rack-and-pinion arrangement.
