Lew 1800 Jump is Greifenberg’s winch especially designed for the drafting of
the snow milling machine on ski jumping hills. The Lew 1800 Jump is approved
for towing of the snow milling machine with a driver on board, and is equipped
with all safety devices.
It features a double-roller equipped with dual braking system: one integrated in
the electric engine, while the disc brake with hydraulic pliers is installed directly
on the drum. Torque control, like in the Lew 1800_R functions as a safety sensor
alerting the operator if the winch exceeds the speed limit and it is expected to
stop automatically in case of slack rope.
