From day one we saw a huge improvement in productivity in our Cat 730 Dumpers. Prior to lining our dumpers with Quicksilver we had average of around 5 cubic meters of hang-up in our trucks. Once we had 7 trucks lined (which only took 8 days) we increased our productivity by about 210 cubic meters an hour. At that rate the liners will be paid for in no time and we will reap the benefits for the rest of the trucks life.
