EZ-EX (single telescoping and double-telescoping boom sections)

For over a decade the EZ-Systems Boom-Extending Hydraulic Deck Crane has proven to provide the highest state-of-the-art yacht crane technology in an aesthetically pleasing design. The EZ-Systems hydraulic deck crane is available in lifting capacities of up to fourteen-thousand pounds (6500-Kgs), and in working boom lengths starting at fourteen-feet (4.26-m) and extending to over thirty-feet (9.0-m). Any of these cranes may be ordered built to the MCA Large Yacht Code (MCA-LY2) or IMO/LSA compliance for SOLAS.

The EZ-Systems Boom Extending Crane’s design provides the efficiency of a compact stowed length with the utility and versatility of variable boom-lengths. The 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 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 telescoping section of this crane. This allows the winch system to move with the extension section, eliminating the need for the crane operator to be aware of the boom-position relative to the headache-ball. The EZ-Systems crane features 280º hydraulic power rotation providing the ultimate in tender-handling convenience. The crane is remotely operated with a wireless joy-stick operated proportional control on an optional-use removable pendant. A pedestal base is the typical mounting structure for the EZ-Systems crane, although a floating-flange standpipe mount or a periscoping standpipe mount may also be used in some applications. The EZ-Systems Crane is typically powered by a hydraulic power unit, available in various horsepower configurations, or may be configured to take power from the ship’s central hydraulic system. The EZ-Systems crane is finished to our highest standards. The aluminum structure is chromated and then primed with a two-part epoxy primer. Then 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 AwlGRIP urethane spray-applied paint finish in a color to match your vessel. The crane system is assembled and installed onto our specialized dynamic load-testing center where our quality assurance team load tests and inspects every crane we produce prior to delivery to the customer. Classed cranes are tested under survey in liaison with the specified classification society.

SYCARA IV represents the cooperative effort between Nautical Structures and Burger Boat’s continued commitment to designing and building custom equipment and custom yachts that meet their owner’s specific requirements and desires.  Styled after the classic yachts of the 1920’s, SYCARA IV brings together the design talents of Naval Architect Bruce King who developed her hull lines and acclaimed Yacht Designer Ken Freivokh who worked with the owner and led the Burger Design Team to develop the interior and exterior designs.  Nautical Structures' designers and engineers were tasked with the challenge to develop modern equipment for this project without compromising on the period classic style.

The deck crane is a 2-1/2-ton capacity EZ5500EX Deck Crane System customized for this application.  A extra low-profile design was developed to help integrate the crane into the aft seating.  The crane was mounted onto a periscoping standpipe that vertically raises the crane almost a meter for deployment; positioning the crane in a more 'typical' configuration for use.  Specialized upgrades were made to the crane design including stainless steel Wandfluh K9 valves and LED floodlights integrated into the boom section.  The design of the crane coupled with the specialized mounting system allows the crane the ability to "dissapear" when stowed, leaving only the classic tender to be admired on deck.

EZ2500EX-SOLAS Crane/Mast Combo - M.Y. Quantum of Solace

Walking the docks at the 2009 Ft. Lauderdale International Boat Show show you will see several new projects delivered by Nautical Structures.  We are proud to have been associated with some very special projects recently.  The M.Y. Quantum of Solace (ex-Midlandia; a 52-meter Benetti) was at the show after a brief refit period in the Rybovich Shipyard, Palm Beach, Florida.  Nautical Structures was asked to develop a unique fore-deck crane for the yacht.  This crane; an EZ2500EX-168-237-SOLAS is a fully-classed Lloyd’s Register of Shipping & Cayman Islands Shipping Registry approved Rescue Boat Launching Crane built to the IMO/LSA Rules for SOLAS.  With a twist…  The crane is also designed, styled and approved to deploy as the ship’s steaming mast; deploying the navigation lights at the appropriate height above the deck and approved by CISR for this dual purpose. 

The crane stows in 168" / 4.26-meters and deploys to 237" / 6.01-meters.  A safe working load capacity of 2500-pounds / 1136-Kg certainly doesn't rank this crane as one of our larger systems, but it's a work-horse nonetheless.  Aluminum construction and components designed for a wet marine environment ensure that the crane will require minimal maintenance and provide exceptional service over the life of the yacht.  The crane provides enhanced cable payout of 12.9-meters / 42.3-ft of Spectra composite-fiber line with a self-stowing hook/weight arrangement.  The headache-ball is machined with a very unique pin-system; allowing the crew the ability to switch between the heavy load-release SOLAS hook and a lighter cargo hook as necessary.  The hydraulic linear winch system incorporates our lanyard-actuated free-fall system, enhancing the deployment speed of the crane.  A specialized hydraulic power unit was manufactured to supply power to this classed crane.  It is configured with two motors; an AC motor for every-day use, and a 24V DC motor for emergency power supply should the vessel encounter a dead-ship condition. 

The crane's telescoping boom extension incorporates a mounting socket for attaching the removable light-bar, mounting the navigation and anchor lights.  The unique design allows the lights t be easily serviced, or even removed whn not needed.

The project was contracted on the first of September 2009 and delivered on the twenty-second of October; going from concept to completed project in under seven weeks.  This was only possible due to the significant efforts of our suppliers, and support of Wally Nisbett / Murray & Associates, the cooperation of Rybovich Shipyard, Cayman Islands Shipping Registry and the amazing effort of all of the Nautical Structures' team in order to pull off the impossible!  On Friday fifteenth of October the crane was tested at Nautical Structures’ Largo manufacturing facility with a Lloyd’s Register surveyor in attendance.  The crane went through testing and was issued a LRS certification number and approval for installation. 

There were numerous challenges involved in the process of developing this unique design.  The Flag State had to approve the dual-purpose design.  The crane had to “look” like a steaming mast while still performing to all applicable standards as a SOLAS Rescue Boat Launching Crane.  The crane was configured to deploy to a fully vertical position, and built to live in a very wet environment on the foredeck of the 52-meter yacht.  The end result is an attractive deck crane that does deploy as the steaming mast; form meeting function in an effort of superb engineering and manufacturing.
