OPTIONAL EQUIPMENT
Choice of cutters, pump handling equipment, air conditioning or heating, anchor
booms, production measuring equipment, and pipeline components.
Mud Cat reserves
the right to modify equipment in order to provide for engineering
improvements.
HULL - One piece welded
steel construction with ladder well forward. Built in fuel,
hydraulic oil and ballast tanks. Hull shell plate and stiffeners
designed to ABS river rules.
MAIN DREDGE PUMP UNIT - V belt driven by radiator
cooled Caterpillar diesel engine with electric starter. Totally
enclosed anti-friction radial and thrust bearings with impeller
mounted on Acme threads. All wearing parts 500 BHN minimum
chrome alloy cast iron. Choice of 10" or 12" (254
mm or 304 mm) discharge pipeline diameters.
HYDRAULIC POWER PACKAGE - Triple section
hydraulic gear pump direct driven off the main engine. Hydraulic
system includes three independent operating circuits; one
for swing winch, one for cutter, and one for spud and ladder
hoist.
EXCAVATING MODULE AND LADDER - Cutter direct
driven by gear type hydraulic motor. Spline connected
to planetary reduction gear. Maximum cutter force available
at all speeds. Underwater excavating module features
short drive shaft with weight concentrated at the cutter
for efficiency.
LADDER HOIST - Double acting hydraulic cylinder. Ram
cylinder operation provides crowding action for tough digging.
POWER SWING WINCHES - Individual single
direct line winches direct-driven by gear-type hydraulic
motors through planetary reduction gear. Speed and
reverse controls at operator's console. Heavy-duty
hydraulic system provides constant line pull at variable
speeds.
ELECTRICAL SYSTEM - 24 volt DC internal/external
lighting and electrical system is powered by main diesel
engine.
SPUDS AND SPUD HOIST - Heavy wall, cylindrical
steel spuds mounted in spud keepers at stern. Spuds
are hoisted by vertical hydraulic cylinder and choker sling
arrangement.
ASSEMBLY AND TRANSPORTATION - Can be accomplished
in 1 day provided all tools, site preparations and personnel
are available. The assembled Series 370HP can be transported
on one truck with the spuds stowed on deck.
WARRANTY - Mud Cat warrants its equipment
only in accordance with the printed warranty conditions which
are normally included in our sales proposals, the latest
copy of which will be forwarded promptly on written request. No
other warranties are provided.

" DRAGON" Model
Series 370HP Using 12" Floating Pipeline
Note: Calculated
output curves indicate pumping capability only. In actual
practice the material varies from free flowing, easily excavated
material to compacted and/or difficult excavations. When
used for estimating actual outputs, the nature of the material
must be considered. Consult Mud Cat for other dredging conditions
outside these curves.
