Businesses that deal with heavy materials cannot manage their operations without gantry cranes. Gantry cranes are the overhead cranes with an overhead beam that gets support from freestandings legs. Gantry cranes move on track, rail, or wheels. Gantry cranes carry a hoist, trolley, and bridge. These cranes are widely used in shipyards, warehouses, workshops, railroads, construction sites, etc. Traditioanal gantry cranes have been in use for decades. Nowadays, protable gantry crane has gained wide popularly across many indutrial sectors. The load lifting capacity of small gantry cranes is a few hundred pounds while the large gantry cranes can lift loads up to several  hundred tons.

Types of Gantry Cranes

Gantry cranes are designed differently making them suitable to life loads of different capacities. Gantry cranes have different shapes and sizes, thus they can easily adapat to be used in any industrial sector. The common types of gantry cranes are:

Full Gantry Cranes: This is the traditional gantry crane having cross beams, a hoist, and legs. They use rails, whees, or tracs for moving.

Semi Gantry Cranes: A semi-ganry crane is mounted on the wall on one side for support and has one leg on the other side. A semi-ganry crane consists of brige, trolley, and hoist. Semi-gantry crane combines the features of an overhead crane and a gantry crane. They can be used indoors and outdoors. In many worksites, semi-gantry cranes are installed below an overhead crane so that work-efficiency is increased.

Portable gantry cranes: A portable gantry crane is mounted on caster or rubber wheels and they are lightweight. They can lift loads ranging from half a ton to five tons. Portable aluminum gantry cranes are lightweight and cost-effective solution for lifting materials.

Adjustable gantry cranes: Adjustable gantry cranes may be fixed or portable. The height, horizontal beam, and width of these gantry cranes can be adjusted . They offer convenience and flexibitly. The small aluminum gantry cranes are more popular because they are cheaper and can be used for handlign different kinds of materials.

Single girder gantry cranes: these cranes have only one girder to hold and move the hoist trolley. These cranes have support legs, main beam, cross bem, controls, hoist and crane drive. If neded, these cranes can be adaped for different working conditions as two leg gantry crane or semi-gantry cranes.

Double girder gantry cranes: These gantry cranes have two girder beams and the trollyes may run on the top or under the bridge. They are ideal for carrying extremely heavy loads. These gantry cranes have high stability, strong load-bearing capacity, and longer life span. These can also be adapted into two-leg or semi-ganty cranes. Apart from these gantry cranes, there are other gantry cranes such as L-shaped gantry crane, box gantry crane, truss gantry crane, U-shaped gantry crane, and workstation gantry crane.
