LIFE

Travellers of the 16 & 17 No. Ring frame ware changed at the same time ( after three days ). So, we can said that lifespan of the LRT travellers and R&F travellers are same in average. But, Compearing the condition of the travellers ( burn out, loaded travellers etc. ) we can said that, lifespan of R&F travellers is some more, than LRT travellers.
