Irwin, PA, January 17, 2014 – Irwin Mine and Tunneling Supply, an affiliate of Irwin Car and Equipment, recently purchased TDT, a Mt. Hope, WV-based manufacturer of portable rock dusters and belt clamps. Those products are used in a wide range of mining applications. TDT’s spot dusting and re-dusting equipment complements Irwin’s line of bulk rock dusters that can be customized to the specifications of mine operators. All production will occur at Irwin’s Blairsville, PA facility, which totals more than 50,000 square feet.

“This acquisition gives us the ability to be a single-source supplier for all of our customers’ rock dusting needs,” says William Baker, President and CEO of Irwin Car and Equipment.  “By expanding our product line, we’re making it easier than ever for customers to engage in best practices and enhance employee safety.”

The spot dusters and re-dusters may be skid-mounted or equipped with rubber tires. They feature hoppers that can accommodate loads of 700-4,000 lbs., and can dust up to 500 feet from the duster through a 2-inch hose. A direct-driven auger transfer provides a continual flow of dust at 50-90 lb./hr. for maximum efficiency. 

The TDT belt clamps that Irwin will manufacture have a 3,000 lb. pull rating and may be used on belts up to 7/8” thick. Depending upon the model, the belt clamp features a 3/8” chain or cable and can be pulled across top rollers.
