FULLY ELECTRIC POWERED DREDGE FOR SALE
Dixie, 10” discharge x 12” suction cutter head,
Model CS-10, Series 100 electric hydraulic dredge
This heavy duty 10” portable cutter suction dredge is designed for one-man operation with a production rate from 100 to 300 cubic yards per pumping hour at discharge distances of up to 4,000 feet, depending on materials and pumping conditions
2. Hull Center Section:
The main hull center section, measuring 35’ x 10’ x 5’, houses all the machinery and controls and is transported intact. The assembly is all welded steel construction with sides, bottom, rakes, and ends of ¼” plate, right angle seams are capped with angle. 4” channel longitudinal runners add 4” H-beam framing on 24” centers form the rigid structural members of this heavy duty hull.
The main engine, reduction gear, and main pump are all mounted on 8” I-beams assuring permanent alignment during severe operation.
3. Hull Side Sections:
The two 40” x 5’ x 5’ rectangular hull side sections are rigidly fastened to either side of the hull center section by the use of the unique Dixie hull side section connectors at the bottom, bolted at deck level. These sections are constructed of ¼” plate with ¼” x 4” interior ribbing and are divided into three water tight compartments. Quick opening man holes are provided for access to each bunker.
4. Elevated Control Room:
The lever room is elevated to give the operator 360 degree vision. This completely separate compartment houses the one-man fingertip control console which includes all operating gauges such as hydraulic pressure gauge, main pump motor amp gauge, K-Ray meter, Jet pump amps, and Hoffer valve controls. Swing winch, ladder hoist, rear winch, variable speed controls for swing and cutter circuits, motor starting/stopping with speed control, and emergency cut-offs are within easy reach of the operators position. The forward windshield is raked to reduce glare and improve vision during rainy weather operation.
The main dredge pump is powered by a 400 HP, GE, 600 RPM, 2300/440V, Type HT-410 slip ring motor with controls and resistor banks for 30% speed reduction, and a manual oil immersed primary circuit breaker. This motor was just rebuilt.
6. Auxiliary Power:
The auxiliary equipment is powered through hydraulic pumps by a 125 HP, 1800 RPM, 2300/440V squirrel cage.
7. Fresh Water System:
The fresh water pump (seal water for the main dredge pump) is a Crane-Deming 6 x 4 x 17, Model 5063.
8. Main Dredge Pump:
A heavy duty, 12” suction x 10” discharge Ni-Hard Thomas Simplicity dredge pump. The pump is mounted with the center line below water level, thereby increasing operating efficiency and eliminating costly and time consuming priming procedures. It is a fully adjustable pump of the highest quality.
9. Hydra-Jet Pump:
The dredge is equipped with a Thomas “Hydra-Jet” unit which increases pumping efficiency. This unit is powered by a Goulds 6 x 8 – 17, Form 3405 pump.
10. Ladder Hydra-Drive Cutterhead Assembly:
The ladder is constructed of rugged structural steel with a length of 42 feet.
The hydra-drive cutter unit is mounted on the lower ladder section and is ruggedly constructed to provide long trouble free life. The 90 HP unit is protected by a pressure relief valve which prevents possible damage due to cutter hang-up or impact load.
A Hofer Valve (Suction Relief) is installed, inline the suction tube to help prevent pipeline plug-ups. Fully automated or manual control.
11. Hauling and Hoisting Machinery:
The two swing winches, rear winch, and ladder winch are each independently powered by hydraulic motors. These winches have a variable speed control and are rated at 30,000 pounds. The hydraulic circuits are protected by pressure relief valves.
12. Hydraulic System:
The hydraulic oil system for transmitting power to the cutter and hauling machinery has three separate independent hydraulic circuits driven by the auxiliary electric motor. All hydraulic pumps are direct driven and fitted with maintenance free flexible couplings. A dual filtering system is included to insure long trouble free life of the system.
