Problems solved by technology
Such known monitoring systems for construction machines suffer from the limited reliability of the status description on the one hand
The monitored exhaust variables (exhaust temperature and exhaust pressure) mainly only identify problems with diesel engines
On the other hand, monitoring systems are still relatively complex, as visual inspections must be performed by maintenance personnel

Embodiment Construction
[0075] Such as figure 1 As shown, for example, a construction machine 1 in the form of a crawler excavator can be monitored, wherein in particular one or more transmissions can be monitored by means of sensors. For example, the traction drive gear 3 and the swivel gear gear 2 can be monitored. Such as figure 1 As shown, the traction drive transmission 3 can, for example, drive a sprocket of a tracked chassis, while the slewing mechanism transmission 2 can adjust and rotate a rotary platform 4 , which is mounted rotatably about a vertical axis. On the chassis 5 including the travel drives. The cab 6, link arm 7, other drives and counterweights and other construction machine components can be mounted on the rotating platform 4 in a known manner.
[0076] Such as figure 1 As shown, instead of and in addition to the transmissions 2 and 3 described, sensors can also be used to monitor other service-relevant components of the construction machine 1 , for example the drive motor ...
