A Gantry crane is an industrial crane designed to hoist and lower heavy objects and materials by using a pair of powered cranes. A Gantry crane system consists of a tower crane and a ground crane. The crane system is then connected to a forklift or pallet truck. The hoisting and lowering system works by cranking the crane up and down, in and out, and over varying ground levels. Gantry cranes are used in many different industries, including construction, for lifting heavy loads. A Gantry crane is used to lift loads that cannot be lifted using other techniques, such as a platform. They are most often used on projects that involve lifting very heavy loads from one location to another, and usually for objects that cannot be moved on a standard truck or forklift. They can range in size from huge "full sized" cranes capable of lifting several tons, to very small, special purpose Gantry cranes used for smaller loads. There are three major types of Gantry cranes: single track, tandem, and wire rope. The most common types of single track cranes are used when there are two or more loads to be lifted. In these cases, the crane system moves vertically in tandem with the platform, and the operator moves the crane along a track between the source of power and the destination. Tandem gantries are supported by rails on either side of the frame, and these are used to lift and lower loads. Wire rope cranes can only be operated vertically; they have no lateral support, so the operator must move the crane along the rails and platforms to reach the desired location. Another design feature that makes Gantry cranes different from other types is their large counter-rotating wheel arrangement. Instead of having two large wheels on the top of the unit, these wheels are located alongside the engine unit. The reason for this design is to prevent deck wear and tear on the engine unit as well as the actual crane itself. These wheel arrangements also allow the crane to more accurately calculate the lift that it requires to safely transport a given weight over a given distance.

A heavy panel may be installed between the window and the exterior frame to protect it, and the inside panel can block sunlight from entering the room. Other uses include installing internal air conditioning systems, securing fragile items such as electronics equipment and moving heavier objects. Gantries are often mounted on rooflines to provide easy access to all areas of a Gantry system, and are also commonly used as a transfer point for objects being transported from one area to another. In the past, gantries have been used exclusively for lifting heavier objects, but advances in materials and technology have made it possible for them to perform a wide range of tasks. Today, they are commonly used to lift lighter objects and to perform specialized tasks. They can be used in a variety of applications and can make any job easier. In the industrial and manufacturing setting, gantries are sometimes used to help maintain a factory floor or as a transfer point for goods. Many companies prefer to outsource their heavy construction work to gantries instead of to traditional crane companies because the cost of labor and the risk of damage to machinery are both reduced.
