According to U.S. Patent 2,857,062, there is one 35 movable bridge on a vehicle loading area known. On the bridge there is a The invention relates to a slewing crane that can be moved transversely along a loading bay. An outrigger area movable loading crane with one on one with a trolley is not available. The crane Height-adjustable horizontal slewing ring can be moved from any position without changing position pivotably mounted boom, on which a 40 the entire loading area plus the load Trolley is movable. next to all four sides of the loading area. Of the There are movable cranes on the loading area. Cranes are operating on the loading area, the latter is therefore known, which are designed as portal cranes (German reduced in size for picking up the load.

Both sides of the loading The invention has the task of providing a U-irons are provided in which rollers run 45 A loading crane that can be moved along a loading area, each of which supports one leg of the portal. The transverse is to be realized, that of any head of the portal is formed from a horizontally mounted crane column from every point of the load and horizontally to the longitudinal direction of the vehicle as well as a load next to each of the four bar frames the underside of which can reach a Ku vehicle side. The crane is to be attached to the money slewing ring, which carries the boom with 50 while driving in a vertical and horizontal rich trolley. The boom will be as narrow and low as possible up to 90 °,
swiveled and must be blocked at the portal, for this purpose the boom is unequal in two before the trolley divided its activity of loading and unloading long arms, of which the shorter arm from the side of the vehicle. Because the Ta- on its underside in the area of the end of the division operation only when the 55 is blocked at 90 ° carries another horizontal slewing ring, Cantilever can take place, is the place of the vehicle by means of which the Iänzu provided with the trolley the load to be taken over always inevitably more arm can be swiveled underneath the shorter arm set, a disadvantage is also the arrangement of the and of which the shorter arm is also on Portal legs. the two long sides of the loading head end of a telescopically extendable crane column area, since the portal, in particular when driving under 60, is arranged with its foot end in the middle ζν, ϊ-von Trees, through contact with their branches, can be seen lateral undercarriages on one in lower Accidents.
