Choose Gantry Cranes For Convenient Lifting And Loading



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.
