ELLICOTT® reserves the right to modify equipment in order to provide engineering improvements.
HULL - Five tank design; quick connect/disconnect assembly; machinery in unitized center tank. Outboard pontoon tanks for flotation, ballast, and fuel storage. Hull bottom and side plate is 0.31 in. (7.9 mm); reinforcing up to 3/4 in. (19 mm); all of A36 or equal steel. Approximate operating draft of 4 feet (1.2 m). Deckhouse integral with center tank storage.
DIRECT-DRIVE CLOSE-COUPLED PUMP UNIT - Heavy duty dredge pump is designed and manufactured by Ellicott® for maximum efficiency over a wide range of dredging conditions. Pump case, impeller, liners and throat piece are cast of special 500 BHN chrome carbide abrasion resistant iron. The pump is designed to facilitate maintenance and parts replacement. The close-coupled direct drive features totally enclosed oil lubricated reduction gear and heavy duty roller bearings on the impeller shaft. The pump is directly driven by a Caterpillar diesel engine equipped with heavy duty heat exchanger and oil filters.
HYDRAULIC POWER PACKAGE - Three hydraulic pumps are direct driven by heat exchanger cooled Caterpillar diesel engine. Hydraulic system includes four independent operating loop 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 - Winch directly driven by heavy duty hydraulic motor through totally enclosed planetary reduction gear. It includes hydraulically operated, totally enclosed disc type brake for holding the load.
POWER 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 - A 120/240VAC/60 HZ AC internal/external lighting and electrical system is powered by belt driven generator driven from the auxiliary engine.
SPUD AND SPUD WINCHES - Two heavy wall, cylindrical steel spuds are 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.
