EZ Deck Crane Hydraulic Knuckle Boom Series - 1

EZ Deck Crane Hydraulic Knuckle Boom Series 2,500/20,000 lb 1134/9070 kg EZ-SYSTEMS KNUCKLE-BOOM TYPE HYDRAULIC DECK CRANE For over a decade the EZ-Systems Hydraulic Deck Crane has proven to be of the highest state-ofthe-art yacht crane technology in an aesthetically pleasing design. Nautical Structures manufactures the knuckle-Boom crane design in capacities from 2,00lb to over 20,000lb (1,134kg to 9,070kg), with and without hydraulic telescoping boom sections. The EZ-7700-KB shown above is a 7700lb / 3492kg capacity crane featuring a fold-under boom design.The crane has been engineered and designed as a true yacht crane, not just another marinized commercial crane. The EZ-Knuckle-Boom Crane’s aluminum boom is capable of being loaded to its full safe working load capacity in any position without restriction. The intelligent engineering inherent in this design allows distributed load-deflection across the boom during moments of high dynamic loading, reducing the amount of shock-loading transmitted to the deck. Virtually silent-operating, our Hydraulic Linear Winch system, a totally non-fouling winch design reflects the innovative and dependably safe operating characteristics built into the boom. This feature adds the additional element of operational safety as the winch travels with the boom during operation of the crane. This prevents any possibility of two-blocking the system causing damage to the composite line. In applications complying with the MCA Mega Yacht Code, the Linear Winch is capable of being placed into a freefall condition with operational control by the operator. The crane features 330º hydraulic power rotation providing the ultimate in tender-handling convenience. Control of the crane is with a remotely operated wireless joy-stick proportional control on a removable pendant. Manual hydraulic controls are also provided, located behind a hinged and latched access panel. A low-profile cylindrical style pedestal base is the typical mount for the EZ-Systems Knuckle-Boom Crane, although a standpipe mount may also be used in applications with GRP constructed vessels. The EZ-Systems Knuckle-Boom Crane is finished to our highest standards. The aluminum structure is etched and then primed with a two-part epoxy primer. The system is faired smooth, and then primed again. The crane is hand sanded, then moved into our heated finish booth where it is coated with a two-part urethane spray-applied paint finish.Our standard colors are Matterhorn white, Off white and Snow white. All other colors will be special order and quoted upon request. With MCA-LY2 Mega Yacht Code compliance, the crane system is static load tested to 2.2 x design load and then dynamic load tested to 1.1 x design load. Warranty: 1-Year including materials, electric, hydraulics and labor. See warranty for details.
