PBHs CRUSH MULTIPLE STRUCTURES
IN COLORADO CLEANUP

from our September, 2000 Issue

What was once an important site for the manufacture of nerve gasses is being given back to nature. The U.S. Army's 27-square-mile Rocky Flats Arsenal in Colorado is now a wildlife preserve ... home to deer, eagles, rattlesnakes, and prairie dogs.

But there is still a great deal of cleanup to be done. Environmental Chemical Corporation of Burlingame, CA has been at this location since May, and their work won't be finished until the end of September at the earliest. Environmental Chemical brought with them their expertise in removing hazardous materials, their highly-trained, licensed personnel, and two Tramac PBH Crusher/Pulverizers (they own a 625 and rented an 800M for this job). They have contracted to take down the gas manufacturing plant, warehouse facility, and storage bunkers (124 structures in all). According to Gary Dotson, Job Superintendent, his people go inside to remove asbestos, old PCBs and any other hazardous material before the demolition can begin. There is an approved Superfund landfill on the Arsenal grounds for proper disposal.

PBHs Crush Massive Foundations
Environmental Chemical's PBH625 is mounted on a John Deere 230LC. Their rental 800M (the dealer is Colorado Machinery, Colorado Springs, CO, rep: George McDaniel) is mounted a John Deere 330. Dotson told us the equipment has been working great, the 800M providing the increased production they were looking for. "It's doing a fantastic job."

The foundations are 10' deep and the slabs are 2' thick. They are broken first with a hammer and then the PBH munches them down to the proper size for removal. The separated rebar is washed and sent out for recycling, the concrete trucked to the landfill. Tramac's PBHs are designed to pulverize concrete ranging in thickness from 24'' to 36'' in a single action. These are high-production units which owe their efficiency to their patented fin-shaped tooth design, requiring far less power to crack material than traditional pyramidal or pointed teeth. Tramac's front tooth splits material lengthwise instead of only chipping away at the edges.
