This 1960s vintage electric-powered chain-ladder dredge was manufactured by Hartman-Fabco, well known for their chain-ladder machines.
It is equipped with a 10×12 Thomas Simplicity Series J36 dredge pump, and powered by a 500-hp, 3600/480-volt Westinghouse electric plant. Electrical switchgear includes a 4000-amp capacity transformer on tandem-axle carrier. The 45’ ladder is fitted with a 7”-pitch chain, reported to be in very good condition. Auxiliary equipment includes a jet pump. Owner reports 350 tph sand and gravel production.
Located in Michigan, this dredge needs some TLC, but is worth a look at this price
