Their crusher for breaking down large stones into smaller rocks had a fault. It was a mobile crusher that could move on caterpillar tracks, but they had lost power to the remote to control the tracks and they needed to move the crusher because they were planning to blow part of the quarry that day.

We were called in the late morning and asked to come out as quickly as possible. We were able to make our way over within an hour and found the fault quickly giving the guys plenty of time to get the crusher out of the blast zone.
