- the by articulated arms 12 and Thrust arms 13 formed unit is also commonly called crane boom 18th designated.
- the rotating crane 4 is vertical by means of a rotary drive 19 or axis 20 running perpendicular to the plane of the subframe 5 rotatable.
- On the crane column 10 is in one with the help of a drive 21 horizontal plane perpendicular to said axis 20 movable counterweight 22 stored.
- a control device 23 is assigned to the rotating crane 4, which is connected to a Overload shutdown device 24 and with a pressure sensor 25 for detection of the pressure in the lifting cylinder 14 is connected.
- a transverse inclination with respect to the machine longitudinal direction in with respect to the horizontal is a bank measuring device 26 with the Machine frame 2 connected. It is also used to record the angle of rotation of the slewing crane 4 in relation to the machine longitudinal direction Swivel angle measuring device 27 is provided.
- the slewing crane 4 is equipped with length measuring devices 28. This are each formed from a cable potentiometer 29, which is used for detection the extension length of the piston on the one hand with this and on the other is connected to the cylinder of a push cylinder 17.
- Driving cabin 30 At the end of the subframe 5 opposite the rotary crane 4 is one Driving cabin 30 provided. Is located below the crane boom 18 a loading area 31. There are three on each long side of the machine frame 2 supporting legs 32 spaced apart from one another in the machine longitudinal direction are fastened. These have a vertical hydraulic drive 33, the support shoe 34 can be lowered for support on the threshold end region. To capture a signal generator 35 is provided in the support position.
- a motor 37 is equipped with travel drives 38 and with a hydraulic system 39 to act upon the various drives in conjunction.
