A long time ago, man has needed to lift heavy loads. Our ancestors had no easy way of accomplishing this. They used other humans to move and lift loads of extreme weight. Eventually, cranes were invented, allowing the lifting of both heavy and very large loads. Today, cranes are used in a variety of settings, including construction sites, shipping yards, and factories. The type of crane needed will be determined by the type and location of the load. Gantry cranes are built on structures and are often portable. This allows them to move from location to location. There are several types of gantry cranes such as rail mounted gantry crane, portable gantry crane, cantilever gantry crane, single＆double girder gantry crane, RTG cranes,etc. And the following are several gantry cranes details.
Different Gantry Cranes Advantages＆Disadvantages
Gantry cranes differ from other types of overhead cranes. They have A-shaped legs that have wheels on the bottoms. Most gantry cranes are built from aluminum or structural steel and can lift tons of weight at one time. A gantry crane with cantilever consists of bridge trusses or girders which extend transversely beyond one or both sides of the crane runway.
A rail mounted gantry crane is usually powered by electricity or steam and can move along a rail as it lifts the load. A Fixed height gantry crane is set at a certain height and cannot be lowered or raised. These types cranes are usually found in factories where there is a ceiling and are used to lift heavy items and products.
An adjustable height gantry crane(or portable gantry crane) can be raised and lowered and has ridges along the support beams. These ridges allow the crane to move up and down and lift heavy loads to different heights. The single girder gantry crane is smaller than most of the other models and is used where a load needs to be lifted, but there is not a lot of room, such as a storage facility within a factory. These types of cranes have wheels which allow them to be easily moved within the building.
The double girder gantry crane is heavier and stronger than the single girder and is used to lift heavier or larger loads. Its design is similar to the single girder but allows it to lift extremely large crates as well as very heavy loads.
Another type of gantry crane is the container crane. This is a specialized gantry crane that is used primarily in shipyards to unload and load ocean-going vessels. This type of gantry crane is mounted on horizontal rails. When a load is lifted, the cantilevered support beam moves out and is spaced to fit the length of a standard freight container. When this happens, the crane moves along rails and the extended cantilevered beam carries the load from the quay out to the ship. Upright cantilevered container cranes have wheels which run along the tracks so they can position the containers anywhere along the length of the ship.
Why Choose Cantilever Gantry Crane In Daily Lifting Work?
Depending upon where it is used, the cantilever bridge or regular gantry crane is the best solution for moving heavy loads. It is used on construction sites, at shipping yards, and in factories to help move large and heavy containers to a new location.
