ELLICOTT reserves the right to modify equipment in order to provide for engineering improvements.
| Specifications - "DRAGON" Model Series 370HP |
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 - Pump compartment sized to allow dredge to remain afloat when pump
compartment is flooded to the main deck. 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 - Ellicott 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.

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 Ellicott for other dredging conditions outside these curves.
