Gantry/goliath Crane-
Goliath cranes, also known as Gantry or Portal cranes are free standing factory cranes that
run on fixed rails on floor. FabTech goliath cranes are available in single girder and double
girder designs. We also manufacture semi-goliath design, where one end of the crane is
overhead gantry supported and one end is floor mounted.
Gantry cranes are usually considered when there is a reason not to incorporate an overhead
runway system. Full gantry or semi-gantry systems are often utilized for heavy fabrication
works, or in some kind of outdoor yard, like steelyards, rail yards, scrap yards and shipping
and container yards.
Special protection is provided for outdoor duty cranes depending on application and
agreement with buyer. These special features may include – corrosion allowance in design
of main load bearing structural members, drilled holes on walkway to avoid accumulation of
rain water, localized full cover for trolley, covers for long travel motor/ brake, additional
parking brake for long travel motion, special paint etc. Special storm anchors are provided
to prevent toppling of crane under storm condition.
The cross travel and long travel motor gearbox unit is designed to overcome wind resistance
opposing the crane movement in addition to the power required to accelerate and move
the safe working load at full speed.
Power supply to the crane is provided through Cable Reeling drum or shrouded bus bar.
