Definitions

  • the invention relates to a crane, in particular a heavy-duty crane, which is mobile by means of an associated chassis arrangement, wherein a chassis-free crane module is provided with a bed that accommodates a telescopic boom and with support beams that can be extended to the side and are equipped with support legs at their ends and the crane module is provided with docking elements and hereby can be docked securely to the chassis arrangement provided with matching engagement elements, and docking elements are provided on the longitudinal and transverse sides of the crane module.
  • a crane of this type arises from the DE 10 2008 047 737 B4 .
  • This is a modular crane with several crane modules that can be docked with one another in the form of a plate module that forms the main component and carries the crane boom, a drive module, a supply module, a set-up module, etc.
  • the plate module that forms the main component is a special version of the known arrangement from an upper, chassis-less carrier sub-module which can be placed on lower chassis sub-modules, the docking elements provided for this purpose being provided on the top of the chassis sub-modules and on the underside of the carrier sub-module.
  • This also has docking elements arranged on its longitudinal and transverse sides. However, these only serve to dock the remaining crane modules to the finished panel module.
  • a wheelless crane module referred to as a superstructure can be placed from above onto an undercarriage that can be placed under it.
  • This is designed as a complete heavy-duty vehicle with its own drive unit and driver's cab.
  • This heavy-duty vehicle is to be used for further transport purposes with the upper structure removed.
  • the heavy-duty vehicle forming the chassis arrangement does not allow the properties of the chassis arrangement to be easily adapted to different purposes and is also not used for docking by means of the The boom of the crane module is manipulated, but is retracted under the jacked-up crane module by means of its own drive device, which is then lowered onto it.
  • the EP 0 919 508 A2 shows a crane with a multi-part frame that accommodates a stand without a ballast boom for the crane boom.
  • This multi-part frame in which the necessary ballast is integrated, consists of a chassis-free middle part and outer frame parts that can be coupled to the front and rear and are provided with heavy-duty castors.
  • the outer frame parts that can be coupled to the middle frame part at the front and rear are not interchangeable, but belong to the frame of the crane, which is only completed by these frame parts.
  • the DE 20 2016 101 503 U1 shows a crane that can be placed on a semitrailer designed as a trailer for transport. Any other movement than by means of the trailer is not possible here.
  • this object is achieved in that landing gear assemblies which can be manipulated by means of the boom and which can be manipulated by means of the boom when the crane module is jacked up on its support legs can be docked to the docking elements provided on the longitudinal and transverse sides of the crane module usable exchangeable units are formed.
  • Chassis units can be manipulated by means of the boom.
  • the crane according to the invention can therefore be converted very easily and quickly to any desired use and can therefore be used variably, which ensures good utilization and thus excellent economic efficiency.
  • the docking elements can be attached directly to the bed.
  • the bed can be taken up on a loading platform, which in turn is provided with the docking elements.
  • This advantageously results in a retrofit kit which enables existing cranes to be easily retrofitted with the measures according to the invention. At the same time, this ensures that the support beams provided on the bed side can pass over the docking elements assigned to the loading platform located below without collision.
  • docking elements can also be attached to both the bed and the loading platform.
  • At least one carriage element can be docked as chassis units for a movement on solid ground on two opposite sides, preferably on the front and rear of the crane, each of which contains a chassis containing the engagement elements assigned to the docking elements and at least has two rollers arranged in pairs.
  • the car elements docked at the front and rear which can be provided inexpensively, enable the creation of a compact crane arrangement that is mobile on a paved surface, the car elements advantageously also being equipped with a loading area and being able to serve as loadable transporters.
  • the rollers can be used as single rollers for a rolling motion on one Hall floor or factory premises. This enables the crane to be easily placed in the desired working position.
  • the rollers can also be designed as road rollers, which can expediently be provided with heavy-duty tires. This results in an arrangement that can be moved on a road and therefore makes it possible to transport the crane as a trailer by means of a tractor.
  • a front carriage element can expediently be provided with a trailer device.
  • a trailer element that can be attached to a front wagon element can be provided, so that a trailer that can be attached to a semi-trailer is created.
