It's hard on gear alright, not so much the hydraulics but pins and linkages on the boom and dipper arm, that's why the charge out rate is higher than normal. We use another one of our machines onsite to dig and load out the rock, saves disconnecting the rock breaker. The job it was on took 2 weeks to break 120m3 rock, not hard out as other things were carried out at the same time. It's not a boring job as it requires a little skill especially when breaking in fractured rock. None of my guys mind doing it. It's on the North Shore removing underground fuel tanks and late next week out West building a new site. We are tits out this side of Xmas with plenty of work in the pipeline.
