3 Types of Gantry Cranes

Gantry cranes are a type of crane that uses a hoist to lift objects. The hoist sits in a hoist trolly, and the trolley can move horizontally on a rail under a beam. Gantry cranes are often used to lift extremely heavy objects, and are often used in building large products, like ships and buildings. Smaller gantry cranes are often used in the automobile industry to lift small, but heavy equipment pieces, like vehicle engines.

There are three variations of the gantry crane, including the container crane, the workstation crane, and the rail-mounted crane. Each type of crane uses the same basic technology and principles to operate, but implement them differently.

Workstation cranes: Workstation cranes are the smallest form of gentry crane. These cranes are small, portable cranes that are used to lift and move heavy objects in a workstation. The cranes are often used in automotive manufacturing plants or other places that work on vehicles. Workstation cranes either use wire rope hoists or chain hoists.

Container cranes: Container cranes are often used to load ships from the dock or land. The hoists extend far out from the actual body of the crane, and are held in place by a cantilever. These cranes were specifically designed to help transfer goods from land to a ship, or from a ship to land. Often the rails on the hoist are positioned exactly in the same size and place as ship containers, which make it easier to move the containers to the correct place.

Rail-mounted cranes: Rail-mounted cranes are also known as Electrical Overhead Travelling (EOT) cranes. Rail-mounted cranes are similar to container cranes, except they are supported by sturdy gantry legs on the ground. These cranes are used in factories to move and lift heavy machines and other objects in production.
