Designing Track Holder DeviceFor Maintaining Spoor Width in Railway Geometry Maintenance

Abstract

Track Holder refers to the efforts of redesigning spoor holder device that has been sold in foreign market. Looking at the use of hammer that causes movement and damage on both the holder and the track, the manufacture of the track holder is intended to attain precise spoor width (1, 067 mm) without causing any damage to the rail components under affordable budget. The manufacture of the track holder should go through three stages namely preparation, assembly/production and finishing. The track holder device that has been designed consists of two motor systems namely the manual system and the electric system. The dynamo that has been installed is Wiper Colt 130 W and 12 V 3 A Battery. Then, the weight per unit of the device is 4 kg while the length of the device is 1.30 m. The track holder device is able to sustain weight up to 3, 282 kg. The prototype of the device was tested on the rail track with three devices and 2-bearing gap. The results of the test show that the track holder device is able to shift the rail track when the fastenings from all of the six bearings are uninstalled. The cost of manual track holder manufacture is IDR 1, 229, 000.00 while the cost of electric track holder manufacture is IDR 405, 350.00. In other words, the track holder device is prominent in terms of technology and price but the use of electric track holder device should be evaluated further on the use of ratio gear and dynamo.
