The addition of Tie Finder Technology results in a machine with intelligent automatic indexing, thereby increasing productivity while reducing operator fatigue. The marriage of probes designed to detect the location of either wood or concrete ties with a machine’s previously existing automatic cycle allows for fully automatic work.
Tie Finding can be added as a factory option or as a field kit to any Harsco Rail tamper featuring the Jupiter II Control System.
The Light Reference System consists of the light buggy, mask sensors, surfacing sensor, and a lining sensor located at the rear of the machine. An encoder wheel by the right rear wheel is also used with the auto curve liner system.
The Surfacing System detects the low spots in the track and the cross level between the two rails. The upper lights on the light buggy shine through the slot in the upper masks on the mask follower. The sensors mounted on the hydraulic and fuel tanks then detect the light and determine the position of the track.
The Lining System detects how far the track is out of alignment from being straight and also determines the proper track position in curves. One lower light on the light carriage shines through the slot in the lower mask on the mask follower. The sensor mounted on the rear rail follower then detects the light and determines the position of the track.
