Mud Cat™ 225D Dredge
A Mud Cat 225D cleans out a mine tailings pond in the US.
OPTIONAL EQUIPMENT:Rotating cutterhead for handling sloped wallsFlow meterDensity meterLiner protection wheelsBroadcaster Discharge Attachment for spray dredgingGPS System (w/sub-meter accuracy)Slurry thickness tattle tailStainless steel components and / or hullPipe, hose, floatsSpotlightClosed loop video monitor for dischargeRemote control option for hazardous environmentsPartial and full automation packages
Easy to use switch controls for all dredge functions.
HYDRAULIC SYSTEM• Closed-circuit hydrostatic
transmission system• Electronically controlled
proportional valves with adjustable flow sections
• Off-the-shelf, top of the line hydraulic components
• Biodegradable oil available
ENGINE• 225 HP Turbo-charged
after cooled John Deere diesel engine
• Full enclosed power unit for weather protection
OPERATOR’S STATION• Easy to use basic dredge controls• A/C and heating systems• Analog gauges• Ergonomic air-ride chair
TRAVERSE DRIVE PROPULSION• Hydraulically driven treble
sheave winch • Electronic speed control • Up to 60 ft. per minute travel• Forward and reverse
CUTTERHEAD (815 MODEL OPTION)• Hydraulically adjustable
mud shield• Hi-torque motor for
heavier materials
CUTTERHEAD (727 MODEL OPTION)• Hydraulically adjustable
forward / backward angle control
• High shroud design for maximum solids intake
LADDER• Downforce hydraulic
ram cylinders for superior excavation power
• Replaceable discharge pipe independent from ladder structure
HULL• 10 gauge steel construction
with internal bulkheads and stiffeners
• Compartmentalized design• Polyurethane foam filled
SLURRY PUMP• Ladder-mounted
submersible hydraulic driven pump
• High chrome construction for abrasive slurries
• 6 in. spherical solids passage
DISCHARGE• 8 in. discharge
with flange connection
FEATURES BENEFITS
Two Cutterhead Options 727 Model for bio-solids materials & 815 Model for heavier, harder to cut materials
Adjustable Cutterhead Allows operator to adjust the cutterhead for optimal performance
Down Force Ladder Cylinder Allows operator to keep positive down-force into material so cutter will not walk on top of it
Electrical Over Hydraulic Allows operator easy control of all dredge functions and simplifies hydraulic
Two Pump Hydraulic System Reduced maintenance and higher efficiency
Traverse Cable Drive System Allows for high torque pulling into materials; cable system can be removed without detaching from anchors
Ladder Pump Ladder mounted pump for higher solids pumping than hull mounted pumps
Pump Defender (patent pending)
Optional patent pending Pump Defender allows for cleaning of the pump inlet after every revolution of the cutterhead to greatly reduce down time in debris rich environments.
Made by Mud Cat Mud Cat invented the auger dredge and continually leads the industry for innovation and quality. Mud Cat dredges are built from the highest quality parts and therefore last longer than the competition.
