In this video, RON HORNER catches up with Danny Hope on one of Hope Civil’s South East Queensland civil sites to chat about his fleet of Cat 637 scrapers and to show the power and grace of these double-engined earthmoving giants.

Danny says he’s had the Caterpillar 637 scrapers for a long time: "I started probably about 1990 with my first one, which is still running around here today. She’s an old girl, but a good girl."

Ron explains how the scrapers work best in tandem. The Cat engine at the front delivers about 500 horsepower (373mW), while the rear one adds 250 horsepower (186mW) to the mix.

"When you run in tandem, that the scrapers butt up to each other — one pulls and the other pushes," he says. "That gives you one and a half thousand horsepower to fill your bowl.

"Once that scraper’s finished filling his bowl he’ll pull out of the dirt, or the material, the second scraper will come in on the back, but still being pushed or pulled, and that still gives you one and a half thousand horsepower to fill that bowl."
