BQE Connector at The Williamsburg Bridge, Brooklyn, New York USA - 2001
Hillman Roller Equipment Used:
- Modified 15-OT Hilman Rollers

This “fast-track” project replaced concrete bridge segments of the connecting ramps 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.
