<p>Lead pick-up devices are fitted to the portal frame while wheel arms which are pivoted by power tools are hinged to the side parts of the portal by horizontal transverse shafts. These wheel arms from a lifting region between setting the container down on the floor and setting the container on a transport vehicle driven into the portal. On each side part, two longitudinally spaced wheel arms (19) are so hinged that in the set down position there is a small wheel base and in the pick up position there is a large wheel base. The side parts of the frame have an A-shaped middle section whose bottom shank ends (22), in whose region the wheel arms (19) are supported, are at a greater spacing than the length of the two wheel arms.</p> |
