About us

aboutEffectively Simple. We believe the simpler a machine is to maintain and operate, the more productive and cost effective it will be.  We take time proven designs and tweak them in subtle ways to maximize their cost effectiveness, durability and performance.

Stewart-Amos is bringing new ideas to an old, established industry. In the last 7 years, we have introduced 6 new and unique sweeper models - with many more to come.

In 1938, 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, engineering, fabrication, manufacturing, distribution, 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.  The street sweeper rental fleet grew to the point that in 2004, a separate company was formed to design and manufacture chassis mounted mechanical broom street sweeping equipment. Stewart-Amos Sweeper Co. combined the talents in engineering, fabrication, and manufacturing from the Equipment Co. with the capabilities of sweeper specific personnel brought on board to spearhead the product line.


Currently, we make 5 different mechanical broom sweepers in three different size categories.  Each incorporates our exclusive “3 shaft elevator system” that minimizes chain wear, slashes maintenance costs and ensures more effective sweeping of all types of debris – especially bulky materials.


Our regenerative air sweeper units are built with stainless steel, bolt-together panels that resist rusting and minimize repair costs, which ensure longer run times and easy accessibility.  They come standard with 5-year, no-rust-through warranties.


All Stewart-Amos products are proudly made in the United States at our Harrisburg, PA locations.
