Hard as steel
February 1st 2011 Fabricator opts for two double girder cranes and one single gantry crane for steel work
Greek integrator Metallotechniki has delivered two Verlinde
double girder cranes (20 tons x 18m), and one single
girder gantry crane (10 tons x 18m) to Glezelis Mantikos.
Glezelis Mantikos make bespoke steel constructions, usually as
a sub-contractor. The two double girder cranes are used in the
production hall of a steel construction factory. Each crane is
equipped with a VT404 main hoist with lifting capacity of 20 tons
and a VT204 secondary hoist with lifting capacity of 5 tons. The
hoisting speed of the main hoist is 4/0.6m/min and the speed of
the secondary hoist is 5/0.8m/min. Both hoists run on individual
trolleys with a cross travel speed of 20m/min. The height of lift of
the cranes is 7m. The cranes are calculated for a lifting capacity of
20 tons. The normal loads are below the 10 tons mark and
sometimes there is a need for two fixing points for the load (this
is the reason for choosing two hoists on different trolleys). For
normal loads that are less than 5 tons, the secondary hoist is used.
Only when heavier loads need lifting is the main hoist activated.
The single girder gantry crane is a modification of an older
gantry crane. The old end carriages and drive units have been
used and a new main girder and legs have been manufactured
using a VT304 hoist from
manufacturer Verlinde. More articles from Verlinde Lifting Equipment: |
