NLCIL engineers rise to the occasion again
The Bucket Wheel Excavator (BWE) L&T IV in Mine-II that got rested on the receiving boom of the machine due to puncture of lower confined aquifer was retrieved, repaired and re-deployed by the Engineers' of NLCIL on August 6.
On February 8, during the second shift, both Rear Steering Tracks (RST) BWE L&T – IV suddenly got bogged in New Lignite Bench 1 conveyor on the non shifting side as a result of a puncture of lower confined aquifer causing sudden outburst of water flow below RST. Since the superstructure was tilted, the discharge boom of the machine rested on the receiving boom of the Mobile Transfer Conveyor-10 that was working in tandem with the BWE. The superstructure of the machine was in a unstable condition since the counter weight boom also rested on the discharge boom.
Three teams comprising of technical experts were formed to work round the clock for the challenging task of retrieval of the BWC and completed the task within 62 days without any injury to any human nor damage to the machinery. Subsequently the BWE was moved and parked at a safer location in Lignite Bench.
