Definitions

  • the invention relates to a mobile console crane with in the horizontal plane rotatable or non-rotatable boom and movable trolley thereon according to the preamble of claim 1, which can be used or retrofitted in particular in unfavorable, cramped spaces.
  • Console cranes are mainly used in closed halls with the task of creating a second independent crane level below a bridge crane level.
  • console cranes When constructing console cranes, it is customary to design them with a jib that can be rotated or not rotated in the horizontal plane.
  • the console cranes each have two crane wheels to support the dead loads of the crane and trolley as well as the lifting load on a vertical crane runway girder.
  • the cantilever moments from the crane, trolley and lifting load are usually introduced by four, but at least by three horizontally loaded pressure rollers via a horizontal pair of forces into two horizontal crane runway beams, which are arranged approximately vertically one above the other.
  • DE-OS 21 21 583 is a single-girder overhead crane in box construction with a Z-shaped bracket trolley which can be moved on a girder.
  • An essential feature of this invention is that the cat is mounted by means of vertical running and supporting wheels mounted at different heights and horizontal guide rollers.
  • the horizontal guide rollers also serve to absorb horizontally directed reaction forces from diagonal pull as well as from attachments attached to the trolley.
  • These horizontal guide rollers run on both sides of a third rail additionally attached to the underside of the carrier.
  • the Z-shaped cat frame can be adapted to different tools.
  • a task of this type is adequately reduced in material, production and assembly costs, which means that the console crane according to the invention is less expensive to purchase and operate.
  • this object is achieved in a console crane of the type mentioned in the preamble of the main claim in that the crane is arranged in the area of one or two parallel crane runway beams transversely to the direction of travel of the crane, horizontally offset to the jib tip, individually or in pairs, vertical or inclined crane wheels.
  • These vertical or inclined crane runner wheels engage on the crane runway girder or on its projecting parts in such a way that they are supported on the one hand on the top and on the other hand on the underside.
  • the inclined position of the crane wheels is preferably in a range from approximately vertical to approximately 30 degrees to the vertical.
  • bracket cranes with small cantilever moments only two individual vertical crane impellers are preferably required to accommodate all cantilever moments and vertical loads.
  • Either a box girder or two bending girders running in parallel with or without height offset can be used as crane runway girders.
  • the new console crane can be designed with the smallest wheelbase and thus minimal space requirements, which offers good opportunities for cornering.
  • the reason for this is that the distance between the wheels and the boom can be kept to a minimum.
  • Guide elements such as rollers and rails have a supporting effect.
  • console cranes according to the invention are more diverse Art.
  • the crane wheels closer to the jib tip perform a double function, namely they take on all vertical loads from the crane, trolley and lifting load as well as from the vertical pair of forces, so that by eliminating the previously usual Console cranes required horizontal pressure rollers fewer supports are required.
  • the resulting decisive advantage is the significant reduction in crane height, which is also associated with a corresponding reduction in weight due to the elimination of the large head girder for the vertical crane impellers required for conventional gantry cranes and the upper cross girder for the upper horizontal pressure rollers.
  • This crane width measured via the crane buffers is reduced by about half in the single-girder bracket cranes according to the invention and in particular in the case of the cranes supported by means of individual vertical crane impellers compared to the conventional bracket cranes.
  • the reduced crane height results in a lower need for hall height for new buildings. Associated with this is the possibility of retrofitting the new bracket cranes in halls with a low construction height, in which conventional bracket cranes cannot be used due to the lack of a hall height.
  • the simple, light and therefore inexpensive design of the new gantry cranes means that they can also be used for much smaller capacities for which the use of previously used gantry cranes was excluded for economic reasons.
  • a crane runway girder 1 in the form of a hollow box as a bending torsion girder is provided for the mobile console crane according to the invention, which is fastened on hall supports 2.
  • the Crane runway girder 1 can also be formed by two bending girders running in parallel with or without height offset.
  • the boom 3 receiving the trolley 4 has at its end facing away from the jib tip a vertical bracket 5 with a rocker arm 6, in which two vertical crane wheels 7, which are lower than the crane runway support 1, are mounted.
  • an impeller housing 8 is connected to the boom 3, which accommodates two vertical upper crane impellers 10 which can be driven by the drives 9; in addition, the impeller housing 8 has buffers 12 for reducing the impact in the longitudinal direction of the hall.
  • bracket crane 5 and 7 show a variant of a bracket crane according to the invention, which is suitable for the use of bracket cranes with small cantilever moments.
  • auxiliary rollers 13 of small diameter are provided as support rollers.
  • the lower cross member 14 with the lower crane wheel 7 and the auxiliary rollers 13 is rigidly connected to the crane.
  • FIG. 8 shows a further example of the possible uses resulting from the small overall height.
  • two can do more if the hall height is sufficient drive as two of the console cranes according to the invention with staggered jib lengths on superimposed crane runway girders.
  • the crane which is located higher up, has a sufficiently longer boom in order to be able to transport its load past the lower crane.
