  • EP 2 163 415 A2 discloses a refrigeration machine for refrigerated vehicles which is attached to the refrigerated space above the pivotable driver's cab. So that there is no collision with the refrigeration machine when the driver's cab is pivoted, the refrigeration machine can be pivoted upwards.
  • US 2014/0251711 A1 describes a mechanism with which the driver's cab of a towing vehicle, together with a cab extension, can be moved forward into a service position.
  • the driver's cab is lifted off the chassis and moved forward without tilting, but the necessary structural requirements are considerable.
  • the object of the invention is to improve a driver's cab of a towing vehicle of the type described above, which has a cab extension that projects beyond the windshield in the direction of travel, in such a way that it can be moved from a basic position for ferry operation to a service position for service and maintenance purposes as easily as possible can be tilted.
