There are a lot of reasons why you may need a 20-ton gantry crane for your business. To determine whether or not you could benefit from one of these cranes, it is helpful to first learn a little bit more about what they are, how they work, and the benefits that they provide.
A gantry crane is a special type of overhead crane that sits on its own two legs rather than being mounted on runways. Traditional bridge cranes are used inside of buildings, with a large girder spanning the distance between two walls. The ends of the girder are attached to special runways that are mounted on the walls, allowing the crane to move along the length of the building.
In some ways, gantry cranes are similar. Like a standard bridge crane, they have a large girder that is designed to span the distance over any objects that are being lifted. The main difference is that they are mounted on legs rather than being attached to the building.
This provides quite a bit more versatility in terms of how they can be used. For instance, gantry cranes are often used outdoors at shipyards, container yards, or loading docks. Since they are freestanding, they don’t need to be used inside a building. https://aicranemachine.com/.
The way these cranes operate is fairly straightforward. At the bottom of each leg, there are wheels that allow the crane to be moved around. Depending on the size of the crane and the amount of weight that it is designed to carry, these wheels can either be made out of rubber or metal. Cranes with metal wheels run on tracks, much like a locomotive. Cranes with rubber wheels, on the other hand, can move freely over any smooth surface that is strong enough to support their weight.
A trolley moves from one side of the crane to the other along the length of the girder. The trolley carries a hoist. To use the crane, the operator moves it into position, ensuring that the girder spans the area over the item that is going to be lifted. Next, the trolley is moved along the girder until the hoist is directly above the item.
The final step is to attach the hook to the load, allowing the object to be raised into the air. Once the load is airborne, it can either be moved from side to side along the length of the girder or the entire mobile gantry crane can be moved to a different location, carrying the load along with it.
The primary reason why you would need a 20-ton gantry crane for your business is if you plan on lifting heavy objects regularly. Having one of these cranes is a convenient, efficient way to move items that weigh as much as 40,000 pounds.
If you are still on the fence about whether or not your company could benefit from one of these cranes, consider reaching out to a manufacturer to discuss your options. They can help you decide whether a gantry crane is the right choice for your business.
