Gantry
crane is a crane built on top of a gantry. It is a framework used for
straddling objects. Portal Crane is another name given to these cranes as portal
is the empty space straddled by gantries. These cranes are usually wheeled and
run on tracks. The use of a gantry crane is mostly felt in dockyards as these
are the only equipment that can lift load brought in by the ship and position
them in the dockyard. However due to advancement in technology, portable
aluminum cranes use the same method to lift and carry load from one working
zone to another.
As a Convenient
Machine
Other than being mobile load carriers, Gantry Cranes have many more advantages.
These cranes are designed with I-beams that support the entire structure while
it is lifting and carrying heavy-duty items. Since a gantry crane comes with
height adjusting features, it can pass around an object easily to transport
heavy items. These cranes are capable of lifting and transporting materials to
heights where human labor cannot reach quickly. Along with this, you can also
decrease the height of a gantry crane to help it transport items through
doorways and narrow passages.
Specialty of Gantry
Crane
All
contractors consider Portable Gantry Cranes to be economical mode of weight
lifter and carrier as the equipment is capable of carrying load that weigh
three tons or more. Since they are portable contractors can assemble and
disassemble the framework whenever they please. Two workers are enough to carry
the disassembled structure, from one location on the construction site to
another, and assemble the same. These cranes are absolutely safe to use as each
piece is set out in the market after going through a load carrying capacity
test.
Significant Facts
About The Framework
All
portable Gantry Cranes come with trolleys attached to them. While the hook
lifts the load, the trolleys of the crane carry the load. Each aluminum gantry
crane comes with an A-frame leg that has wheels attached to it. These wheels
can also be replaced by rubber treys to help the crane to travel smoothly on
delicate roofs. Alongside this, all portable cranes come with an I-beam that
supports the crane when it lifts and positions heavy items. All gantry cranes
come with lock casters. Each caster in these cranes is sized in accordance to
the weight carrying capacity of the equipment.
Aluminum Vs
Container Cranes
While
Aluminum Gantry Cranes are portable cranes used in factory workstations to lift
and position heavy items, container cranes are used for lifting items from a
ship and transporting and positioning the same in the dockyard. While a
portable crane gets its major support from its A-frame legs, a container crane
gets its support from a strongly built pillar known as I-beam. Like Aluminum
cranes, container cranes, too, have wheels but while for the latter, the wheels
help them to move along a rail track while the former mayor may not run on rail
tracks. To read more Click Here
