OPTIONAL EQUIPMENT
Accessories and options can be offered and delivered with the Series 670 "DRAGON". Included are a 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 670 |
HULL - Three tank design; quick connect/disconnect assembly; fuel oil storage and machinery in unitized center tank. Outboard pontoon tanks for flotation and ballast. Hull shell plate and stiffeners designed to ABS river rules.
MAIN DREDGE PUMP UNIT - Gear belt driven by heat exchanger 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 12" or 14" (304 mm or 355 mm) discharge pipe diameters.
HYDRAULIC POWER PACKAGE - Tandem hydraulic gear pump direct driven off the main engine. Hydraulic system includes three independent operating circuits; one for swing winches, one for cutter, and one for spud and ladder hoists.
EXCAVATING MODULE AND LADDER - Cutter direct driven by high torque, 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.
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. High torque, heavy-duty hydraulic motors provide 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 a sling operated from a hydraulic cylinder.
ASSEMBLY AND TRANSPORTATION - Assembly can be accomplished in 2 days provided all tools, site preparations and personnel are available. The disassembled Series 670 can be transported on three trucks.
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.
