Gantry cranes and their applications
If you are in a material handling industry, you must have heard the word Gantry Cranes multiple times. Gantry cranes are usually referred to as an overhead bridge crane system. Also, there are different types of overhead bridge cranes that are also considered as Gantry cranes. One of the best things about gantry cranes is that they can be used and implemented in various types of industries without any difficulties due to their different shapes and sizes. In order to determine the usage and applicability of Gantry Cranes, some of the factors such as the girder configuration and the crane size are taken into consideration. The top Gantry Cranes manufacturer in Ahmedabad knows the specification of these cranes and manufactures them according to their implementation and client’s requirements. Also, there are various types of Gantry Cranes which we will be discussing later.
With the help of the hoist trolley, Gantry Cranes are able to lift heavy objects and move both horizontally on a pair of rails that are fitted under the beam. Gantry Cranes are usually deployed in the places where there is a requirement of lifting heavy loads as it specialises in that. Places where goods cannot be brought to the cranes, Gantry Cranes are usually used as they are mobile and can be moved easily. Gantry Cranes are also called portal cranes sometimes as the word portal is used to describe the workspace of the crane.
Types of Gantry Cranes
There are various types of these cranes available which are discussed in brief below
- Full Gantry Crane system that consists of two legs which ride on a rail where they usually run in a straight line in the dedicated areas only.
- Semi Gantry Crane system that run on a single leg rail and are extremely useful in the areas where there is a very little workspace
- Portable Gantry systems run on rubber wheels and are usually very light in weight.
- Adjustable Gantry Cranes allow the operators to adjust the crae according to his requirement owing to its variable height design.
Full Gantry Crane
The load carrying part of the crane in case of full gantry cranes lies below the gantry and is supported firmly by a beam. There is a complex network of attachments and cables that supports the whole crane structure which is the reason why these full Gantry Cranes can counter attack the torque from the load. All thanks to this mechanism, extremely heavy weights like engines of the ships can be carried using these vranes. The world’s largest Gantry Crane is capable of carrying 22000 tonnes which is deployed in China currently.
Rubber tired Gantry Crane
As the name suggests, these carnes have wheels of rubber tires and because of this structure, these cranes do not need a rail for their movements. When it comes to size, these cranes are usually smaller than other Gantry Cranes which is why the rubber tires can easily handle their loads. Rubber tired Gantry Cranes are used when an easily movable crane is required that can be easily carried and navigated through multiple rails. Rubber tired Gantry Cranes can easily lift heavy loads to good heights which is why they have a wide applicability. Maximum space can be utilised by using these cranes where there is a size restriction.
Workstation Gantry Crane
Workstation Gantry Cranes are used by the small or medium sized factories as these cranes are smaller in size and are able to easily lift lighter loads in no time. These carnes can be moved when unloaded while are stationary when under load which is a big advantage. Wire rope hoists are used as the hoisting mechanism in the Workstation Gantry Cranes while in some cases, chain hoists with lower capacity are used as well.
Applications of Gantry Cranes in different industries
There are many types of Gantry Cranes available and each one is used in a specific industry which is discussed in brief below
In the shipbuilding industry, the most deployed cranes are the Gantry Cranes as these industries require a lot of heavy weight lifting to be done in the sites which is only possible using Gantry Cranes. Some of the heaviest parts of the ships like the engine itself can be lifted easily through Gantry Cranes and are extremely useful in the building stages of the ships
Automobile engines are comparatively lighter and there are cranes which can be deployed for lifting those weights. The cranes must be such which can help in lifting those light weights with ease and can work in lesser space as well
Warehouses demand lifting of heavy weights all the time and Gantry Cranes are extremely helpful in such scenarios. This is the reason Gantry Cranes are available and deployed at almost all the warehouses.
Manufacturing units require lifting of weights that are lighter hence Gantry Cranes which are small in size are usually deployed in manufacturing units. These cranes have a capacity of 4 tons due to which even bulk loads can be carried at the same time.
In construction sites, Gantry Cranes are usually deployed as they demand lifting heavy loads and carry materials present in that area.
