Design
HADEF electric wire rope winches for stationary
use are fitted with holes for installation. The
housing is made of steel plate. The two housing
halves are connected by threaded bolts and
distance tubes. The rope drum between the two
housing halves offers wire rope exits in several
directions. Different installation positions are
possible - make sure the drum axle is always
positioned horizontally.
