OPTIONAL EQUIPMENT
Accessories and options offered include choice of cutters, pump handling equipment, air conditioning or heating, production measuring equipment, and pipeline components.
ELLICOTT reserves the right to modify equipment in order to provide engineering improvements.
| Specifications - "DRAGON" Model Series 1170 |
HULL - Three tank design: quick connect/disconnect assembly; machinery in unitized center tank. Outboard pontoons for flotation, ballast and fuel storage. Hull bottom plate is 0.31 inch (7.9 mm), side plate 0.25 inch (6.35 mm) reinforcing up to 3/4 inch (19 mm); all of A36 or equal steel. Deckhouse integral with center tank structure.
DIRECT-DRIVE CLOSE COUPLED PUMP UNIT - Close-coupled unit, totally enclosed radial and thrust bearings on reduction gear shaft with ACME threads for impeller mounting. Pump case, impeller, liners and throat piece are cast of special 500 BHN chrome carbide abrasion resistant iron. Driven by heat exchanger cooled Caterpillar diesel engine with electric starting. Choice of 14 inch or 16 inch (356 mm or 406 mm) discharge pipe diameters.
HYDRAULIC POWER PACKAGE - Three hydraulic pumps are direct driven by a Caterpillar auxiliary diesel engine. Hydraulic system includes four independent operating circuits; one for cutter, one for swing winch, one for ladder hoist, and one for spud winches and control pressure. The engine, hydraulic pumps, gears, cooler and reservoir are all mounted on a common base.
EXCAVATING MODULE AND LADDER - Cutter driven by slow speed, radial piston hydraulic motor. Maximum cutter force available at all speeds. Underwater excavating module features short drive shaft with weight concentrated at the cutter for efficiency. Cutter can be angled down for shallow digging. Excavating module drive recessed inside ladder tube for protection.
LADDER HOIST - Double acting hydraulic cylinder. Ram cylinder operation provides crowding action for tough digging.
SWING WINCHES - Individual single, direct line winches, direct-driven by radial piston hydraulic motors, mounted on the aft end of the ladder. Speed and reverse controls at operator's console.
ELECTRICAL SYSTEM - 24 volt DC internal/external lighting and electrical system is powered by auxiliary diesel engine.
SPUD AND SPUD WINCHES - Two heavy wall, cylindrical steel spuds mounted in spud keepers at stern. Spuds designed for single-part wire rope bottom lift, and are raised or lowered by individual single drum winches with free-fall clutches.
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 and job conditions must be considered. Consult Ellicott for other dredging conditions outside these curves.
