Abstract: A device for transporting workpieces to be machined and worked having a base housing or frame which may be moved on wheels and a bed which holds workpieces. The bed is connected with the base frame via a scissors mechanism and can be raised by the scissors mechanism. The scissors mechanism comprises arm braces wherein one arm brace at one end is pivotally connected to the base housing and the other arm brace on one end is pivotally connected to the bed wherein the arm braces are connected to each other at approximately the center thereof via a shaft. The wheels are mounted on the shaft which connect the arm braces and the wheels are pushed out of the base housing as the bed is lowered. The arm braces on the other end opposite the pivotal connections have a free end comprising a sliding foot which slides on the housing floor. In the resting position, the sliding foot engages under a cross rod lying above the housing floor.
