Abstract:  
PROBLEM In 2018, a Munkebo customer of 15 years needed to recover and recycle spent steel grit while blasting the concrete and steel structures of a 900-foot bridge. The contractor had a niche business in surface treating small-to-medium-sized bridges. However, the work area on the riverbank beneath this bridge was especially difficult to reach. Furthermore, the work area was too small to fit most portable vacuum and recycling systems, in addition to power and air generators. As a final concern, the riverbank was unstable—too much weight concentrated in one area could cause it to collapse.
