Fairbanks 2000 SERIES Rocker Column Railroad Scale - Manual (Page 7)

1-C: Rails & Anti-Creep Devices
The Scale is designed to accept a 115 lb. rail with Foster #62 rail clip. The approach rails
and Scale Weigh Rail should be the same weight. The approach anchor bolts, approach rail
plates, rails, rail clips, and anti - creep devices are all optional items. They can be supplied
by Fairbanks Scales when ordered as accessories, otherwise they are not supplied.
Positive means must be provided to prevent the creeping of the approach rails and to main-
tain a clearance which shall be not less than 1/8 inches or more than 5/8 inches between the
approach rails and the weigh rails. Switch points are highly recommended for the purpose. A
minimum of seventy five (75) feet of tangent track at each approach is required by the A.A.R.
(Association of American Railroads).

Connection
Anti - creep devices are constructed of angle iron with a flat iron weldment to fit to the rail as
shown above, The rail is side drilled through its web and bolted to the anti - creep device,
effectively securing it from any movement.
The AAR Scale Specifications state that the rail on the approach and the weighbridge shall be
properly anchored to prevent creeping of the rails. This is done in order to maintain the prop-
er gap between the approach rail and the weighrail.
