The TracFeed® SFA remote motor drive is installed on the contact
line pole and it is connected to a switch via a final controlling ele-
ment. A shift linkage provides the mechanical connection between
the TracFeed® SFA remote motor drive and the switch’s adjusting
lever.
The TracFeed® SFA remote motor drive is driven by a direct cur-
rent motor. Power transmission is via a tooth belt, with the power
then converted into a linear motion by means of a threaded
spindle. The linear motion of the threaded spindle creates a stroke
at the adjusting lever. The stroke of the adjusting lever can be
selected as 100 or 200 mm.
The TracFeed® SFA remote motor drive can be moved to its
default position using the crank handle.
The TracFeed
®
SFA is designed for use in the outdoor area of
overhead contact line systems. The drive meets the requirements
of
DIN VDE 0100
and the technical regulations of Deutsche Bahn
AG.
