Definitions

  • the invention relates to a ring lift crane according to the preamble of Claim 1.
  • a well-known ring lift crane is in the Mannesmann Demag construction machinery company brochure "Ring lift Granes" CC 2000 RL; CC 4000 RL, edition 11/82.
  • This Ring lift crane has a ring that can be erected and a circular lane on, which consists of several interconnectable segments.
  • Within the Ringes is an undercarriage and one that is rotatably connected and several winches having superstructure arranged.
  • the superstructure is included in both end areas each connected to an adapter, which is arranged on the adapters via Swinging interconnected roller sets on the circular track of the ring support rolling.
  • the center of the ring or undercarriage is the center of this the axis of rotation.
  • One adapter is for holding a counterweight and one other adapter as a support element for one articulated at the free end of the adapter arrangable boom designed.
  • the rotary movement of the ring lift crane is by means of a ring gear arranged on the inside of the ring and therein engaging pinion mounted on rockers.
  • To stabilize the Overall construction is the undercarriage with different reinforcement struts Sections of the ring connected.

  • the platform is connected to an adapter in each of the two end areas Support roller sets arranged on the adapters by rolling on the ring, whereby the center of the ring forms the axis of rotation for the platform.
  • the one-piece ring is secant and within the Stiffened ring struts.
  • two parallel struts each have a piston-cylinder unit arranged on their a support leg can be arranged at the free end.
  • the caterpillar can be locked with the support element. In this way, the ring lift crane is considered The whole can be moved.
  • a disadvantage of the latter construction is that the size of the Ring diameter and thus the maximum load capacity is limited. Besides, is the type of connection of the ring lift crane with the transport unit cumbersome. Furthermore, the undivided ring requires a lot of space when moving the ring lift crane depending on the local conditions at the place of use is not always available.
  • a generic ring lift crane is known from US-PS 4,196,816. This consists of a stand-up, a circular lane and several ring having interconnectable segments, within which a Undercarriage is arranged, one rotatably connected and several Superstructure with winches and two at a parallel distance from each other has lying bridge girders, which are in two opposite one another Provide end areas with an adapter and the crossbar with the The uppercarriage can be connected and unlocked.
  • the adapters are supported by arranged rollers unrolling on the circular lane of the ring, the The center of the ring or the undercarriage forms the axis of rotation.
  • One adapter is to hold a counterweight and the other adapter to hold one articulated boom.
  • To generate the rotary movement of the Ringliftkranes is a sprocket arranged, its rotary motion on the two Bridge girder is transmitted.
  • the undercarriage is attached with stiffening struts different sections of the ring connected.
  • the disadvantage here is that the components of the crane when swiveling and driving are supported on the ring and thus on the undercarriage. Because of too little The drive power of the crawlers must first be for driving and swiveling Counterweight reductions are made. Because the counterweight is not can be moved, further disassemblies are required to balance the crane (e.g. Boom parts) required. So that the crane can swing or drive, it must on Ring are supported and the support plates are either to be removed completely or turn them all up individually.

In the same sense will continue suggested lying in the area of the counterweight end of the two Bridge girder an extension of the bridge girder projecting beyond the ring to arrange. Both measures have the following advantages: The counterweight can be moved from the position of the normal working position to the counterweight car Towards the center of rotation. This will optimize the focus for moving the ring lift crane on site.
  • the Ring lift crane has a modular structure and as many standardized components as possible be used. This starts with the undercarriage and superstructure, the components of a standard crane. This continues through the boom used and the Winches, as well as the crane cab.
