Gantry cranes are most often used in manufacturing to lift heavy objects vertically, transport them horizontally, and lower them back to the floor. Gantry cranes are cranes that move along a track and employ posts and girders to lift heavy objects. Cranes often employ either electrical or pneumatic power to move objects horizontally, in addition to an attached hoist to raise and lower the object vertically. Cranes come in several forms, such as overhead, rough terrain, and tower. Gantry, jib, monorail, bridge, and overhead cranes can fall into the static crane category.Ī crane is a machine that uses mechanical leverage, wire rope, and/or chains to lift and relocate heavy objects. In contrast, mobile cranes are usually mounted to vehicles, allowing them to be transported from job site to job site. Static does not mean the crane does not move at all, but rather that it moves along a predetermined path. Static cranes, as the name implies are permanently or semi-permanently installed cranes.
