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 (11 hp) 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.
