At the end of December 2017, Antraquip delivered three (3) of their powerful AQ-5 drum cutters to one of their most longstanding customers in New England with plenty of experience utilizing Antraquip attachments for a variety of projects over the years.
For this job however, the contractor was on a particularly tight timeline to complete the controlled concrete demolition of wall within a lock which would need to reopen by Spring to allow large ships to pass through the vital waterway to access the major cities in the northeastern part of the US and Canada. The customer mounted the AQ-5s on three (3) CAT349 excavators and they were positioned on barges from where they would grind the concrete back to the level required. This concrete was not your normal weathered concrete commonly seen on lock and dam rehab jobs but rather 8,000psi (UCS) with steel support imbedded within the concrete. As the machines worked their way down, the water level was dropped in order to access the deeper areas of the lock. The project required operation of the three machines around the clock despite brutal weather conditions with temperatures dropping to as low as -30 degrees (F) (-34 Celcius). Nevertheless, the entire project was completed well ahead of schedule in less than one (1) month.
