Upping its stake in the
super heavy lifting tower
sector is Taegwang
Heavy Industry Co (TGHI)
with a 7,500 tonne
capacity system.
ALEX DAHM reports
Getting 7,500 tonnes
up to 120 metres
T
aegwang Heavy Industry Co (TGHI)
has added 1,000 tonnes to the
lifting capacity of its super heavy
lift erection tower system. The Korean
company already offers an hydraulic lifting
tower system with a rated capacity of
6,500 tonnes. Uttam Kim, TGHI executive
director for global strategy, told
IC
that the
erection tower has now been updated and
upgraded so that it can lift 7,500 tonnes.
Applications include erection of large
structures such as Goliath type gantry
cranes in shipyards that weigh thousands
of tonnes and to erect bridges and tall,
heavy refinery vessels and other chemical
industry and energy sector elements. TGHI
offers the erection tower and lifting service
for rental.
The steel lattice boom structured device
has a maximum mast height of 132 metres
and offers a lifting height of 120 m. For
lifting the 6,500 tonne system has hydraulic
jacking units in up to 12 sets of climbing
blocks. Each unit has four cylinders and
542 tonnes of capacity. Operating pressure
is 290 bar and the stroke is 350 mm. Jacking
Korean company TGHI has increased the capacity of
its super heavy lift erection tower to 7,500 tonnes
TGHI using its hydraulic erection tower to erect a 2,000
tonne capacity travelling gantry crane for Konecranes at
the Engevix Ecovix shipyard
in Rio Grande, Brazil
The hydraulic double acting climbing jack cylinder system for the TGHI erection tower
The operating sequence for the jacking
procedure on the TGHI erection tower
speed is 5 mm per second. Kim said that
the erection tower is designed to operate
in wind speeds of 15, up to a maximum of
20 m per second. It is designed to cope with
a maximum out of service wind speed of
55 m/sec.
Operation is manual from a local display
panel or via remote control. A weight
balancing feature with double-acting
cylinders is designed to equalise all the
load weight evenly so that the tower is not
subject to any asymmetric loading. An

emergency block function is incorporated
to allow operations to stop when the
load is in a raised position. Components
in the climbing block can be replaced
without having to dismantle the tower.
For transport and storage the tower can
be dismantled.
A recent application for the tower
system was on the new 2,000 tonne
capacity travelling gantry crane at the
Engevix Ecovix shipyard in Rio Grande,
Brazil, for crane manufacturer Konecranes.
Other cranes on the project included
wheeled mobile telescopic cranes and a
750 tonne capacity lattice boom crawler.
