The Konrad Mounty is a truck-mounted tower yarder for timber harvesting on steep slopes, with a cable crane system and loading crane on a Mercedes Arocs truck, in three sizes: the Mounty 3000, 4000 and 5000.

Truck-mounted
Every Mounty is built on a Mercedes Arocs 6×6 or 8×6 truck, with other carriers on request, and a tower of 13.0 to 14.2 m.

Crane and head on board
A loading crane of 200 or 220 kNm with a reach of 9.6 to 9.9 m carries a Konrad Woody harvester head, all run on Konrad's KTC 1.0 control and KFS radio remote control.

Konrad Liftliner carriage on the skyline above a Mounty tower yarder

Working uphill and downhill

The Mounty works uphill and downhill. Downhill, it runs Konrad’s radio-controlled Liftliner carriage in the haul-back system: the lifting winch in the carriage lets it travel along the skyline and pull in logs at the same time, which takes load off the crew and shortens work cycles. When working downhill, the wide tower protects the operator.

Harvester heads

The Mounty’s loading crane takes Konrad’s own Woody harvester heads, the WH50-1 or the WH60-1.
