Definitions

  • the subject matter of the present invention is a frame of a mobile working machine, in particular a mobile thick matter pump, which has a lateral loading surface section aligned parallel to a longitudinal direction of the frame.
  • the framework comprises a transport magazine extending along the longitudinal direction.
  • Mobile work machines regularly include such a frame structure, which can be placed directly on a chassis of a truck via a mounting frame or directly, or which can itself form the chassis or at least part of the chassis.
  • Such frameworks regularly include a loading area on which the superstructures required for the respective working machine can be fixed.
  • An elongated transport magazine extending along the longitudinal direction of the frame can be parked on a lateral loading area area, in which objects and/or materials such as operating resources or add-on parts that are required for the work operation can be stored and transported.
  • Such a frame can be used, for example, in fire-fighting vehicles, in which a fire-fighting water tank, a fire-fighting water discharge device and a fire-brigade ladder can be arranged on a central loading area section of the frame. Firefighting equipment can be stored in the transport magazine.
  • a structure as described above positioned on the frame can be formed, for example, by a fold-out thick matter distributor mast arranged centrally on the loading area.
  • a sludge line is usually routed through the sludge distributor boom to deliver sludge pressurized by a sludge pump unit. If a desired application location cannot be reached through the foldable sludge distributor boom, it may be necessary to connect additional sludge lines ( sludge pipes or hoses ) to the sludge pump unit or to be connected to the existing high-viscosity line to extend it.
  • the invention relates to a frame of a mobile work machine, in particular a mobile high-viscosity pump, which has a lateral loading surface section aligned parallel to a longitudinal direction of the frame.

  • the framework is designed to be connected to the chassis of a mobile working machine.
  • the framework itself can also form the chassis or part of the chassis.
  • the work machine can in particular be a mobile thick matter pump (truck-mounted concrete pump). It is also possible that the framework can be detached from the chassis of the mobile working machine in order to be parked on an underground and operated in a stationary manner.
  • the transport magazine is used to transport objects and/or materials such as operating resources or attachments that are required for the work operation.
  • it can have one or more at least partially walled compartments in which the transported goods are protected from external influences.

  • the adjusting device is set up to lower the transport magazine in a controlled manner, utilizing the force of gravity of the transport magazine.

  • the transport magazine includes a quick-release point, by means of which the transport magazine can be releasably connected to the adjusting device.
