Three new ZX470LC-6 excavators are making a splash for Wisconsin-based J.F. Brennan Company, Inc. at a jobsite in northern New York. Over a 7-mile stretch of the river, the three excavators have been dredging and backfilling sediments for a three-year river remediation project.
All three of the ZX470LC-6 excavators operate from barge platforms in the river. This unique application called for some special modifications to make each excavator as efficient as possible.
“Each machine is equipped with aftermarket long reach fronts and additional counterweight,” said Paul Berendes, Brennan’s director of asset management. “The long reach fronts and added counterweights give us the ability to handle 2.5-yard custom environmental buckets at a maximum reach of 60 feet and a dig depth in excess of 40 feet.”
As a marine construction contractor, the majority of Brennan’s work happens on the water. With the unique fabrications needed on the excavators, serviceability and speed in getting the machines on site were important factors.
“Parts availability and service support played a major role in the decision-making process,” Berendes said. “Lead time and ability to get the machines outfitted in time to meet project deadlines also had a part in the decision-making process.”
In the mere 1,200 hours that the excavators have been operating, they haven’t seen any downtime.
“For a typical earth-moving contractor, if their machine goes down, they can just pull one from a rental lot. Our machines are specifically tailored to marine applications, and it’s very difficult to find something of this size and with these capabilities on a rental lot,” said Sam Crawford, project manager for Brennan. “Having these reliable machines with such little maintenance has been very beneficial for us.”
