To Death Valley

It was merely scorching hot outside of Hawthorne Nevada:
Image



. . . . when I spied this nutty contraption in the desert. It looked like the ADHD Refinery Engineers Remedial Training Company:
Image



So I pulled off the road and drove up to the gate. Up the hill was this:
Image

. . . . and rather more hilarious, this:
Image

Those cabovers are a bit spooky, there is nothing in front of you and you are several feet up. This was a Chevy Titan:
Image

Image

Image



. . . . way back from whence I came, my own little pocito Titanette:
Image



In the other direction was a beautifully enigmatic:
Image



We had been talking about the 2 cycle engines over in Williams CA, and here are your intake ports along the cylinder walls that blow the fresh air in and shove the old exhaust out (through the four little valves in the bus example):
Image

The exhaust manifold is huge.
Image


. . . . Connecting rods are not just a VW problem:
Image

This whole big old engine just runs a generator (used to) :
Image
(oh alright, this is the data plate off of its service generator, the main one is more like 800 volts and 3,000 amps!)

. . . . with some pretty big brushes that run a diesel locomotive's wheel motors.
Image



Then I had a thought, here at the ADHD Refinery Engineers Remedial Training Company:
Image

Maybe they were hoping to install the diesel locomotive engine in this:
Image

Image

They were upgrading the brakes:
Image


. . . and putting in the "Big Train" JC Whitney air horns:
Image

. . . . but then again, maybe not:
Image

Later, I visited the Post-Apocalypse Motel:
Image

. . . . with the recent Extreme Makeover treatment:
Image

Image

The only guest there spake "Nevermore":
Image

Image


. . . so I bid "fare thee well" to the raven and drove back into the hot desert:

Its amazing that scraper even has brakes. 80% of the scrapers I work on don't have brakes. Once the brakes ware out nobody ever fixes them. Its about $4,000 to $6,000 per wheel for a brake job on a 657 push-pull type scraper done in the field. How do they stop such a massive machine you ask? They drop or drag the bowl on the ground, which by the way is the recommended and most effective way to stop them.

That old thing had the cam-actuated drum brakes and a large external-contracting band on the transmission output. The skinny lever/rod actuation made me think this was all pretty tough on the operator back in 1948.

. . . at least the operator got to enjoy the sunny day without those stupid parasols and air-conditioned cabs that came later.
