Komatsu 930 vs Caterpillar 16H

This is taking the whole Caterpillar / Komatsu rivalry way too far. Here, an operator on a Komatsu 930 lost control, and drove over the side of the Caterpillar 16H grader.

Massive damage to the grader.

Look at the tire marks on the side of the cab. A very lucky operator.

Norwich Park Dragline Recovery

When we last saw Norwich Park's dragline, it was looking a lot like this. A bench failure had the dragline nearly sitting on its boom.
The plan was to bury two dragline buckets, which were then attached to a stabilising frame. Tension was then applied to the frame to pull the dragline back level, while the dirt was excavated out from underneath the dragline.

Remote-control dozers. Safe, but poor aircon.

In all, an excellent performance from the BMA team to successfully right the dragline and get it back to work. Congratulations on a job well done.
