30 ton overhead cranes are available in many different styles, each of which is best suited to a specific type of job. Thinking about the type of work that you have to do will make the process of selecting a crane easier. Of course, before you can choose a crane, you need to learn more about the available types. Below, you can find an overview of three different types of 30-ton overhead cranes, including information on how they are usually used.
Bridge Cranes
These cranes are the most common types of 30 ton overhead crane. They also usually have the highest lifting capacity.
In most cases, they are installed inside buildings or structures. Runways are installed up toward the ceiling on two walls that are opposite from one another. A heavy-duty girder is mounted between the runways, spanning the distance across the building. The girder can move forward and backward on the runways, allowing it to travel from one end of the building to the other.
The hoist is mounted on the girder. The trolley that it is attached to allows it to travel back and forth along the length of the beam. A cable, wire rope, or chain that is attached to the hoist is used to lift items off of the ground.
Bridge cranes are available in single and double girder designs. As their names imply, single-girder cranes have one girder while double-girder cranes have two girders that are mounted parallel to one another. With double-girder cranes, the hoist is usually mounted between the two girders, allowing them to share the weight equally. Learn more via https://www.dafangcranez.com/
Gantry Cranes
Another type of 30-ton overhead crane is a gantry crane. Like bridge cranes, these cranes have a heavy-duty girder with a hoist. The primary difference is that the girder is attached to freestanding legs rather than being attached to runways on a wall. Wheels on the base of the legs allow the crane to be moved around, either on a track or on the surface of the ground itself, depending on whether the wheels are made of rubber or metal.
Jib Cranes
These overhead cranes have a sturdy support post with an arm that extends outward at the top. This arm is known as a jib. The jib can usually spin around in a circle, covering a 360° area around the crane. A hoist that is mounted on the jib can move back and forth along its length, allowing it to pick up items underneath the path of the crane.
Bridge cranes are commonly used for applications like manufacturing and warehousing. Gantry cranes are frequently used in the shipping industry for stacking and moving containers. Jib cranes are popular for manufacturing and are also used for applications like loading and unloading heavy items from ships.
This look at three popular types of 30-ton overhead cranes should give you a better sense of the available options. If you aren’t sure which crane style to choose, consider discussing your options with an expert so that you can get their input and guidance.
