Cranes come in a lot of different styles, with overhead cranes being some of the most popular. Typically, these cranes are either attached to the walls of the building where they are located or they are mounted on legs. Overhead cranes that are mounted on legs with wheels are known as gantry cranes, while cranes that are attached to building walls are known as bridge cranes.
Gantry cranes are made up of several basic components. Most gantry cranes have two legs that extend upward from the ground. These legs support the weight of the crane. Attached to the base of each leg, there are wheels. Depending on the design of the crane and its lifting capacity, the wheels are usually either made out of rubber or metal. Gantry cranes with metal wheels are designed to run on tracks like trains, while gantry cranes (группа козлового крана AICRANE) with rubber wheels can move over just about any smooth surface.
Spanning the distance between the legs, there is a special beam known as a girder. As you may have already guessed, single-girder gantry cranes have one beam connecting the legs. Double-girder gantry cranes, on the other hand, are designed with two beams that run parallel to one another.
With a double-girder gantry cranes (https://gantrycrane.kz/kupit-dvukhbalochnyy-kozlovoy-kran-tsena/), a trolley is mounted between the two girders. The trolley can move back and forth along the length of the girders, covering the entire distance from one leg to the other. On the trolley, there is a hoist that is used to lift and lower loads.
The way that these cranes operate is relatively straightforward. First, they are moved into position using the attached wheels. Each leg is positioned on either side of the load, with the girder spanning the distance overhead. When the crane is in the right position, the wheels are locked so that it can’t move, ensuring that the setup is stable before the load is lifted.
The trolley and hoist then move along the girder until they are directly over the load. A heavy-duty cable or chain is attached to the load itself and it is lifted up off of the ground by the hoist. Once the load is in the air, it can be moved to another location, either by moving the trolley along the girder or by moving the crane itself on the attached wheels.
Double-girder gantry cranes are usually designed for heavy-duty lifting. Thanks to the fact that they have two girders, they are capable of lifting a lot of weight.
