Although Harcon has become known for its unique Bucket Boats and Bridge Trackers for accessing structures from the bottom side, we also offer solutions for accessing from the top side. We have continued to add new equipment to help our clients finish projects in the safest and most efficient way possible.

Sidetracker Details

At under 3,000 pounds, STU is the lightest weight motorized under-bridge access machine in existence. We’ve fabricated two boom lengths, one which allows us to reach over an eight foot fence. The Sidetracker is perfect for cantilevered sidewalks. We’ve found it also extremely useful on pedestrian bridges or other load sensitive structures where conventional equipment is simply too heavy. Vertical down-reach varies from five to eight feet from deck level, depending on the boom being used.
