The compact yarding system
KR40-2
The KR40-2 is a self propelled, remote controlled skyline crane. The essential difference to the KM40-2 : the hydrostatic chaindrive system!
The compact yarding system
The KR40-2 is a remote controlled skyline crane which is mounted on a tandem trailer. The operation of the installation is remote controlled. To increase the productivity, an automatic drive function of the carriage is standard. Very comfortable is the rigging up of this installation.
All the functions can be operated by remote control. This installation connects a high grade of working safety with an outstanding productivity.
In terms of tractive force, performance data and variety of options, the KR40-2 is identical to its brother, the KM40-2.
Radio technology
For a quick installation and a safe handling, the following functions are controlled by remote:
- Supports
- Putting up the tower
- Radio technology
- Guyline drums
- Skyline winch
- Ram cylinder for tension part of drum
- Guyline winch
- Mainline winch
- Carriage start/stop
