Konrad KMS Tower Yarder
The Konrad KMS is a compact, remote-controlled tower yarder on a tandem trailer, or on tracks, for cable lines of up to 1,000 m, uphill and downhill: the KM40-3, and the newer KM50-1 and tracked KR50-1.
Compact, on a trailer or tracks
The KMS is mounted on a tandem trailer with a hydrostatic auxiliary drive (optional on the KM40-3), or on a radio-controlled tracked undercarriage for the KR50-1, with a tower of 11.0 to 12.0 m.

Run from the remote
The set-up, the winches and the carriage are all radio-controlled, on Konrad's KTC 1.0 control system and KFS-16 or KFS-20 radio remote control.

Remote control
Every function the crew needs for a quick, safe set-up is on the remote: the supports, raising the tower, the guy line drums and winch, the skyline and main line winches, the tensioning cylinder, carriage start and stop, the winch in the carriage, the automatic drive function, handing over radio control, and the horn.
Versions and options
The KM40-3 comes as a 2-cable or 3-cable version. Options include a straw line winch, a long-cable version and additional guy line winches. The 50-1 runs on a tandem trailer with hydrostatic drive (KM50-1) or on a radio-controlled tracked undercarriage (KR50-1).
