Founded in 1996 by five electrical engineers, Pittsburgh-based Richmond Engineering Works designs, integrates and services bulk-material-handling equipment and systems. Its three-discipline engineering team supports machines such as rotary car dumpers and stacker reclaimers, while its in-house capabilities include reverse-engineered replacement parts for both REW and competitor equipment. The privately held company also provides 24/7 field support, including inspections, upgrades and breakdown assistance, and operates a separate oil-and-gas controls business.
