  • the cooling and/or flushing water is used to lubricate and/or clean the piston rods.
  • the water tank 25 is arranged along the longitudinal direction L of the construction machine between the delivery cylinders of the thick matter pump unit 4 and the electrical energy storage device 2.
  • the water tank 5 is arranged along the longitudinal direction L of the construction machine between the electrical drive device 3 and the electrical energy storage device 2.
  • the water tank 5 can be arranged between the delivery cylinders of the thick matter pump unit 4 and hydraulic or electrical linear drives, each of which is assigned to one of the delivery cylinders.
  • the water tank 25 is closed, for example, by means of a removable cover 26 of the thick matter pump unit 4.
  • the construction machine 1 has a free space 27.
  • the free space 27 is used to remove the cover 26 from the water tank 25.
  • the free space 27 is arranged above the water tank 25, against the direction of gravity G.
  • the water tank 25 can form a maintenance opening for servicing the thick matter pump unit 4. Wear parts of the thick matter pump unit 4 can be replaced, in particular regularly, via the maintenance opening.
  • the water tank 25 has, for example, a drain device by means of which the cooling and/or rinsing water can be drained out of the interior of the water tank 25.
  • the drain device of the water tank 25 can be operated from above via the interior of the water tank 25, for example when the cover 26 is removed.
  • the construction machine 1 has, for example, a temperature control system.
  • the temperature control system serves to cool and/or heat the electrical energy storage device 2.
  • the construction machine 1 can have a casing which is attached to the support frame 5 and which shields the components of the construction machine 1 from an external environment of the construction machine 1.
