The performance of the SCP (stamp charging and pushing) machine depends upon proper alingment between the machine and the batteries. This, in turn, is governed by the condition of the track on which the SCP machine travels. The existing track was made from 246 lb/yd rails laid as far back as 1989. It became imperative to renew this track which was in poor condition; but unfortunately, 246 lb rails are no longer available. A 150 rails had to be used as a suitable.
This gave rise to serious problems. The existing foundation bolts were to be used for holding the supporting ottom plate of the new rails, but the width of the bottom flanges of the A 150 rails was greater, leading to fouling of the flages with the foundation bolts. A number of ideas were proposed
 but none were acceptable. One idea, which was mooted was to go for
extensive machining of flanges - rejected since it would result in loss of strength
of rails and it was also expensive. Finally an innovative but simple
idea evolved whereby machining could be eliminatedaltogether. It was decided to insert a
special contoured spacer on the long foundation bolts, thereby raising the level of the
nut above the rail bottom flange. This eliminated the problem of fouling. This breakthrough solution has been tried at Coke Plant 1 and will be fully implemented after the receipt of all A 150 rails. Hey ! Gee wiz, innovation pays ! |
