Above are pictures of different projects we have worked on. The Francisco Overland Conveyor project, is a project where we installed a 120 foot conveyor tube above state route 725 East. The tube houses a 54 inch wide conveyor and weighs 70,000 lbs. It prevents coal dropping from the conveyor onto the traffic below.
We installed a ventilation fan in Francisco, Indiana. It produces about 600,000 cubic feet of air per minute at only 700 revolutions per minute. The rotating assembly of the squirrel-cage type fan weighs 18,000 pounds. The inlet duct is 75 feet above the pit so it will not re-circulate contaminated air back into the mine. The pit floor is 220 feet below the surrounding surface elevation.
Included are pictures of our most recent project. We built a complete rotary breaker and delivered it to a local coal mining company.
