Knuckleboom crane for boats
EZ-KB Nautical Structures

For almost twenty years the EZ-Systems Hydraulic Deck Crane has proven to be of the highest state-of-the-art yacht crane technology in an aesthetically pleasing design. Nautical Structures manufactures the Knuckle-Boom crane design in capacities from 2200-pounds to 11,000-pounds (1000-Kg to 5000-Kg), with and without hydraulic telescoping boom sections.
The crane features a fold-under boom design, with an optional telescoping boom section to enhance the service range. This Knuckle-design allows the maximum amount of reach-range in the most space-efficient (compact) stowed dimension. The crane has been engineered and designed as a true yacht crane, not just another marinized commercial crane. The EZ-Knuckle-Boom Crane%u2019s articulating 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 extending boom. This feature adds the additional element of operational safety as the winch travels with the boom during operation of the crane.
