Offshore cranes need the right wire
ropes for proper operation.
Wire rope is the workhorse of offshore cranes, working
hard and long to lift and move loads to and from the
rig. The leading supplier of wire rope in North
America, WireCo WorldGroup, offers wire ropes that fit all applications
for offshore cranes - even custom fabrication of boom
pendants. Refer to the chart below for complete details
or, for more information, see the WireCo WorldGroup Crane User's
Guide.

Main
hoist rope
|
Flex-X 6
|
Characteristics
needed are resistance to bending fatigue, resistance to crushing and
resistance to wear. Flex-X 6 provides the best combination of necessary
characteristics, plus higher strength. If block rotation is a problem, XLT4,
Flex-X 35 or Flex-X 19 PS should be considered.

Flex-X 35
|
Rotation
resistance is a primary concern in an auxiliary hoist. XLT4 and
Flex-X 35 are the most rotation resistant of these ropes. These are definitely the best choices with
a swivel in the system. For less
demanding applications, Flex-X 19 PS provides a good combination of rotation
resistant properties and resistance to crushing.

Boom
hoist rope
|
Flex-X 9
|
The
primary characteristic needed in a boom hoist is resistance to drum
crushing. Flex-X 9 is best suited to
handle this situation. Flex-X 6 also
works well in many boom hoist applications.
Though alternate lay ropes may be specified on your equipment, it
generally will not perform as well as those listed here.
