Concrete Segment Bridge Launch
LOCATION: Brooklyn, New York USA
pRODUCT: 15-OT MODIFIED ROLLERS WITH ACCU-ROLL GUIDANCE
This “fast-track” project replaced concrete bridge segments of the connecting ramps on the Brooklyn Queens Expressway Connector leading to the Williamsburg Bridge – a vital link between Brooklyn and Manhattan, in New York City.
The contractor utilized two carts equipped with a pair of modified 15-OT Hilman Rollers utilizing Accu-Roll Guidance in a special configuration guiding the rollers along the central median of each support beam to launch the 45-ton pre-cast segments. An excellent example of Accu-Roll Guidance Systems effectiveness for repetitive movements, a total of 240 sections were launched quickly and efficiently using this method.
