Supplier of custom dredges opens in California

By |  September 1, 2017

Aggregate Dredge Solutions is a new company that specializes in custom-built mechanical dredges for the aggregate industry. The company’s services include consulting, design and engineering, as well as installation support.

While specializing in complete customized dredge and conveyor systems, Aggregate Dredge Solutions also offers components and spare parts for existing mechanical dredges.

The new business venture was started by Jochen Rohr, whose family has been in the aggregate business since the 1930s, operating four sand-and-gravel sites in Germany. Rohr was the founder of the Rohr Corp., which was sold in 2011.

Rohr says his focus has always been on new innovative solutions to improve efficiency and dig deeper. He says he works with a select team of experienced engineers and other specialists to come up with technology allowing for onboard materials processing, and customized dredges to account for unique applications, as well as climatic and geographic challenges.

Aggregate Dredge Solutions also focuses on being environmentally conscious. All of the company’s dredges are electric, meaning there are no diesel fumes or exhaust.

“When the bucket is lowered, it is slowed down electronically and feeds energy back into the system, similar to a Tesla,” Rohr says. Additionally, all hydraulic systems are filled with biodegradable oil.

While the business is based in California, it works with local suppliers and subcontractors to build the equipment as close as possible to the site of operation.
