Hydraulic System
Independent electro-proportional circuits allow for simultaneous cutter, swing, and ladder operation. All circuits are protected by suction strainer, return filters and relief valves
Electrical System
- 24 VDC for starting lighting and controls
- 12 VDC (8 amp maximum) for convenience and user furnished radios
- 8 kW belt driven generator off auxiliary engine
- All circuits fused for protection
- Two 1,000 cold cranking amp batteries
- 60-amp alternator
Control System
The DSC LLC control system provides the dredge operator with a simple, ergonomic, and user- friendly interface to efficiently operate the dredge. The system is designed, manufactured, programmed, and tested in house by trained professionals with years of dredge experience. The heart of the system is a PLC capable of monitoring digital and analog inputs, controlling digital and analog outputs, performing automatic loop control, displaying pertinent information, and recording historical data. The dredge control system protects against pump engagement and disengagement at high speed and locks out all hydraulic functions during start-up and control activation. The system also alarms on poor engine conditions, hydraulic and transmission problems, and high bilge water. All of the alarmed conditions, along with the time and date, are logged; the last sixty-four alarms are retained for review.
The dredge control system provides electronic operation of the engine throttle, pump engagement, and all hydraulic speeds and directions. Hydraulic controls are ramped to prevent jarring when controls are started, stopped or reversed. The dredge control system also records and displays the operating hours of all major dredge systems.

Hydraulics
Independent electro-proportional circuits allow simultaneous cutter, swing and ladder operation. All circuits protected by suction strainer, return filters, and relief valves.
Electrical
The controls in the lever room and the emergency lighting are operated on 24VDC service that is supplied from the diesel engines’ electrical circuit. The normal lights and air conditioning are powered by an AC hydraulic driven generator system. The electric circuits have fuses and switches for the different circuits. The Caterpillar Diesel engine has a 24VDC starter and control circuit. See the Caterpillar Operating and Maintenance Manual for more details about the engine electrical systems.
