From Oxford Mining, Kentucky, USA. A Caterpillar 992G with a seriously broken boom 68,000 hours on the machine.

Rear Dumper Into Hopper

That's not something you see every day - a Cat truck painted white!

Bogged Excavator

Sent in this week by a reader. According to the email, the excavator operator decided to take a shortcut by going over the rill.

Lightning Strike on 777

Another great set of photos sent in by a reader of a lightning strike on a 777. From the incident report:

"On July 15, 2012 at approximately 2300 hours driver of 777F haul truck was parked at the 1135 waste dump waiting out an electrical storm.  Truck was struck by lightning causing significant damage to the rear of the truck.  One left side outside duel was propelled away from the truck approximate 250 meters.  The rim of this tire was another 50 meters further.  All 4 rear tires were blown out and cab windows shattered.  Driver exited the truck as quickly as he could and ran away to a safe distance from the truck."

"Driver exited the truck as quickly as he could." Gee, ya think?

793 vs Drill Rig

Received these photos a couple of weeks ago, but with no description or location. Judging by the marks behind the truck, it looked like it might have just come around a corner.

Downshifting in a 793

Lots of people send it photos to this blog. (Thank you!). Normally,  I check them to see if I already have them in my collection, and then put them into the rotation. Sometimes, the photos are so amazing that I just have to put them up on the site right away.

This is one of those times. These photos were sent in this week by a reader. In it, he says that the operator of this 793 downshifted from sixth gear to first. The engine didn't like it. Some rebuilding of the engine may be necessary.

Highwall Collapse Onto Rear Dumper

Otherwise known as 'speed loading the truck'.

Hole Punch

How do you punch a perfect hole into a truck tyre? Like this:

This was done by the Hope Downs mine, on one of their 777 water trucks.

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.

Rolled Caterpillar 785B

Look's like he's managed to slide right down the spoil face.
