Definitions

  • the invention relates to a working machine, in particular a hydraulic excavator, with at least one ballast device, wherein the ballast device comprises at least one ballast weight and at least one ballast support.
  • eye rods which can serve for lifting, for example, a Gußballast or a revolving stage of the machine.
  • the eye rods can be part of the cast ballast.
  • a lifting traverse for example under a corresponding revolving stage, in order to be able to manipulate or lift the cast ballast and / or the working machine and / or the revolving stage accordingly.
  • ballasts In welding ballasts, it is also known to integrate a complex support structure in the ballast or integrate with the ballast weight.
  • two lifting points can be provided on the ballast, for example, in combination with two other lifting points, e.g. can be used on the Monausleger for lifting the entire machine or the ballast.
  • ballast weight and the ballast support each comprise at least two bushings which are aligned with each other.
  • the ballast support may be formed, for example, as a metal carrier, which is part of the structure of the working machine and in particular, for example, a superstructure of the working machine.
  • the ballast weight may be one or more bodies which are made, for example, of a metal or of concrete and, depending on the required ballast weight, may optionally be deposited in different numbers on the ballast support.
  • the at least one ballast weight and the at least one ballast support can each comprise two bushings which can be aligned with one another in at least one position of ballast weight and ballast support.
  • the bushings make it possible to guide a connecting means therethrough and with Structures, for example, the ballast pads, which may be located below the ballast weight to connect. This makes it possible to use an area for coupling coupling means with the working machine, which on the one hand is a statically advantageous area for lifting the ballast weight and / or the working machine and on the other eliminates the need for other lifting devices, such as eye bars or lifting traverses.
  • the ballast pad is part of a turntable of the work machine
  • the ballast weight must therefore not be designed to carry additional weights but it is sufficient to interpret this only to carry its own weight.
  • an advantageously simple construction of the ballast weight or the ballast weights is possible, allowing a more cost-effective production.
  • inventive design of the work machine allows a modular design of the device, in particular coupling means or connecting means can optionally be provided with the working machine or optionally retrofitted.
  • the coupling means can furthermore be easily assembled and disassembled, which can also take place in the construction site of the working machine and not known from the prior art factory or during the manufacture of the machine must be done. The assembly and disassembly of the coupling means can thus also be done later on an existing machine.

  • a working machine according to the invention offers the advantage that even dismounted ballast can be easily lifted by means of appropriate coupling means using the bushings provided on the ballast weight and / or the ballast support.
  • the feedthroughs in the ballast support and / or in the ballast weight can in particular be arranged in a ready-to-use configuration, for example with overlying ballast, in a vertical or in a direction deviating from the vertical direction.
