EZ-Knuckle
Boom
Hydraulic Deck
Crane System
For
over a decade 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 2500-pounds to 8000-pounds,
with and without hydraulic telescoping boom
sections. The EZ-4000-KB-EX shown above is a
4000 pound capacity crane featuring a fold-under
boom design, with a telescoping boom section
included. The crane has been engineered and
designed as a true yacht crane, not just another
marine converted commercial crane.
The
EZ-Knuckle-Boom Crane’s telescoping 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. This prevents any possibility
of two-blocking the system causing damage to
the cable. In applications complying with the
MCA Mega Yacht Code, the Linear Winch is capable
of being placed into a free-fall condition with
operational control by the operator.
The
crane features 360º hydraulic power rotation
providing the ultimate in tender-handling convenience.
Control of the crane is with a remotely operated
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 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
of white to match your vessel. With MCA Mega
Yacht Code com]pliance, the crane system is
static load tested to 2.2 x design load and
then dynamic load tested to 1.1 x design load.
