sway control system to be fitted. There
is also a control system for vibration
suppression and shock free load positioning
in accordance with the length of the hoist
line and a control system for tandem
lifting operations. This synchronized crane
control avoids side pull on the load which
may be caused by the long distance between
operator and load.
Auto-tracking cameras and a remote
monitoring system have also been added
and information and machinery dates are
displayed on one large touch panel screen
to assist the crane driver.
The two first JCC-TS500s will be tested
under construction job conditions by the
end of 2013. A smaller model, the 15 tonne
capacity JCC-TS300 and a bigger model,
the 25 tonne TC-700, will complete the
new series. Both will follow similar design
principles to the existing models.
Unique units
The preference for floor climbing tower
cranes has led to the development of
specialized roof mounted assist cranes
to bring down the climbing crane after
topping out. IHI offers three sizes of
disassembly cranes that can be combined to
bring down even the largest JCC-V series
IHI climbing crane. The largest unit is the
JCC-V190SK with a lifting capacity of 16
tonnes at 12 m radius. The smallest is the
JCC-V10SK, which handles 1 tonne at
10 m radius.
Unique to IHI disassembly cranes
is their climbing mechanism. A small
crane mast can be inserted through the
machinery deck by the crane itself and the
upper crane can be jacked alongside this
short tower. The resulting extra height
of the luffing jib crane is a benefit when
optimising the hook height to reach the
A-frame of the floor climbing crane that is
being dismantled. A result means the boom
foot of the JCC-V190SK will be raised to
13.4 m above the building roof.
To reduce the required under hook
height for an assist crane to remove the
JCC-V190SK, a special rigging frame can
be connected with the base boom section.
By operating the luffing rope connected
Customers can specify a larger
cabin unit with a separate WC
The small JCC-V10SK dismantling crane on the
test ground in Yasuura. Note the inserted pin-
connected tower raising the upper crane above
the slewing unit for extra under hook height
to the rigging frame, the A-frame can
be raised or folded by the crane itself.
In addition, because roof space is often
restricted, IHI disassembling cranes
can have a folding boom to reduce the
dismantling space. All crane components
can be split down into units to be picked
and removed from the roof by the next
smaller lifting device or by hand.
IHI customised jib cranes are delivered
all over the world.
