The industries in the company's initial customer base were not only various types of coal plants, but also cement, chemical, steel, glass, blast furnaces, copper mines, ports, foundries, railroads, shipyards and public utilities.

In 1901, Heyl & Patterson acquired land for a manufacturing plant on Pennsylvania Avenue along the Ohio River in Allegheny City, now known as Pittsburgh's North Side.

In 1904, Heyl & Patterson pioneered the first cranes to lift entire railroad cars, as well as towers to unload barges filled with ore, coal, sand, and slag.

By 1950, Heyl & Patterson installations could be found in almost every industrial section of the United States and Canada, as well as South America, Europe, Asia and Australia.

Though still concentrating in the field of heavy bulk material handling equipment, Heyl & Patterson initiated a diversification policy and added other products to complement its main activities.

A total of 42 trucks mounted on 78 wheels, 30 of which were individually driven, supported and moved the six moveable sections on the largest stainless steel dome in the world.

Florida Operations would serve the aerospace community at Cape Canaveral, and developed a system of blast deflectors for the space program launch pads.

Later in the decade, Heyl & Patterson opened a Service Center in Charleston, West Virginia as a warehouse to stock spare parts.

Heyl & Patterson's North Side manufacturing plant closed in 1970, and was eventually sold to Schneider, Inc., a pipe and sheet metal fabricator.

It served as the field headquarters for projects in Guantanamo Bay Naval Base in Cuba, the Panama Canal Zone and the Bahamas, but was eventually sold off in 1980.

Renneburg & Sons merged with Heyl & Patterson's Process Division to become the Renneburg Division, and the acquisition broadened Heyl & Patterson's scope of fluid bed equipment and rotary dryers, and enabled it to manufacture equipment to process chemicals, pharmaceuticals, fertilizer, metals, fish meal and food.

A pilot plant testing lab facility was built in a different Greentree location, similar to one run by Renneburg, to support the new product lines.

Bulk Transfer also offers material handling equipment such as barge unloaders with both grab and continuous bucket designs, and related specialty machinery.
