Nautical Structures Overhead Beam Cranes are also designed state of the art. With
over four systems delivered to our credit, two systems
currently under production and several projects pending
our beam cranes are fast becoming a more standard product
in our line. Our cost efficiency to produce this equipment
is second to none.
Produced in capacities of up
to 8000 pounds per beam, or greater, our system is designed
to integrate into the overheads of both metal and grp
constructed vessels. Custom heavy-wall aluminum extrusions
were developed and produced to allow our structure a relative
low-profile, and yet still out-reach greater distances
with a minimum of beam deflection.
We offer this equipment in
both mono-beam as well as telescoping-beam construction,
full-beam systems. The Hydraulic Linear Winch System is
utilized for both cable-handling as well as beam-traversing.
The benefit of our linear winch technology is both in
its inherit safety, its superior operating characteristics,
and near-silent operation. With the Hydraulic Linear Winch
System the specified cable payout is met, and limited
in both directions, eliminating the possibility of a two-blocked
condition. We install a tensioning system to eliminate
dangerous traverse backlash.
Our proportional control system
allows the operator to feather the hoisting speed for
absolute control of the load. Both beams may be operated
in unison with one joy-stick, or independently with
one joy-stick for each beam.
