Al Amos founded our company as a distributor of mineral processing and aggregate production equipment for the limestone quarries located in Pennsylvania.

Today, that division has evolved into one of the mid-Atlantic region’s premier suppliers of aggregate crushing and conveying equipment.  With design and layout, distribution, engineering, fabrication, assembly and installation, the staff of the aggregate division brings their expertise to each project regardless of the size and scope.  From turnkey quarry installations to simple plant improvements, Stewart-Amos is the vendor of choice for the aggregate industry.

Also based in Harrisburg, PA; Bob Stewart started a road building machinery distribution company in 1947. The sales of asphalt pavers, compaction equipment, earthmoving machinery, refuse bodies and street sweepers fueled the growth of this division.

With the consolidation of the construction machinery manufacturing industry during the late 1980s and early 1990s, the decision was made for the Stewart division to concentrate on providing specialty wear item solutions for the construction and mining industries.  Also at that time, the Stewart division began renting specialized equipment such as hydraulic hammers, mining and construction dewatering pumps, and street sweepers.
