Gantry cranes are often confused with other crane types, but in truth, they are not like any other crane. A gantry crane is simply a large crane designed to lift and support a work platform, usually on a construction site. They can range in size from massive "full" cranes, able to lift the most heavy loads around, to very small shop cranes used for small jobs around the building site.

Some of the most common types of gantry cranes include the roller, boom, and pike/ramp crane. A roller gantry crane has a long boom and long thin cable. It uses these cables to climb up and down and support the work platform. The cables are set up in tandem so that when one cable breaks, the other can still keep the crane standing. This type of crane is popular in places where there are many different work areas and the distances between them can vary.
Boom gantry cranes are used for large temporary projects and lifting over extremely heavy and dangerous objects. They are commonly seen in construction sites where lifting big heavy objects is necessary. Boom gantries are made up of a mast, spigot, and lifting cage along with a counterweight to help it stay on its course.
There are also trolley gantries, vertical platform gantries, and forklift cranes to name a few. Trolley gantries are often used to move supplies and materials from one area to another. They have a flat bed with a long lanyard and electric chain along with a pallet on top. The chain and pallet are connected to the lifting platform which can be raised or lowered using a hydraulic lift system. Lift forks are also a popular choice for use in construction due to their versatility. Forklifts tend to be a little more expensive than most other types of gantries, however they can perform the job just as well and usually much faster due to their higher speed. See here more info about this crane.
To further increase efficiency, gantries are fitted with systems which are called load cells. These are zones in which different types of loads are allowed to fall. The crane can be guided through the passageway of these zones which will allow it to pick the right load at the right time and height. Most cranes will allow only a certain number of load cells, so if you require more than the number of zones available on your manual crane, it may be worthwhile having a zone control installed.
There are two types of gantry cranes available on the market; the fully automatic or the semi-automatic. A fully automatic crane will be able to pick up both lighter and heavier loads, whereas a semi-automatic will not be able to achieve this level of success. If your company requires a more versatile crane used for both lifting and moving heavy items, then a multi-system crane would be the best option. This type of crane is able to handle both lifting and lowering, however if one system fails, both machines should be able to continue working effectively for some time before one system is brought back up to standard. For industries that are constantly transporting products and are required to maintain safety, a fully automated system will be the most cost effective solution.
