Gantry cranes are one out of the many types available in the market. They are the ones wherein you can see a hoist to lift weights. They are made to move on a rail and are supported by hoist trolleys. They ease your work by helping you move heavy goods from one place to the other. They are generally used in factories, manufacturing units, and construction sites. Gantry cranes help move a heavy good or machinery from one site to the other.
The gantry cranes have remained extremely popular in the shipbuilding industry from the very beginning. They were employed for ship building from where crane straddles the ship to allow big and heavy objects to be moved into and from the ship. Gantry cranes are preferred because of their huge capacity. They can lift weight up to 900 tons and can lift it up to a height of 100 meters. Small gantry cranes are also available that run on rubber tyres instead of rail tracks.
It is natural to find them in huge manufacturing plants, especially steel plants. They can also be used in smaller workshops wherein not so heavy weightlifting is required. They are generally used to transport machine parts from one place to the other, so it is natural to use them in steel plants or metal polishing and cutting industries. They can last for several years together, as generally they are made of good quality. They can cause accidents, otherwise.
They are used in overhead lifting. Hence, their main use is in large premises where there are different sites on the same land. Dams and other such government undertakings make use of gantry cranes. Their use is expanding, at present. Main industries and fields are making use of this machinery. It is a boon to mankind as it makes the job of heavy lifting easy and safe. It has helped considerably in the progress of mankind, right since ages.
