There is a significant difference between a single girder and dual-girder overhead crane. Overhead cranes are simply gantry cranes, those that are typically installed in a facility where there is a substantial amount of merchandise that is being moved. Larger ones will be installed outside with supporting beams, capable of moving large items such as containers from ships to the dock. Regardless of how they are used, these gantry cranes can be constructed with either one or two girders, and here is the primary difference between purchasing either one http://ellsenoverheadcrane.com/single-girder-overhead-crane/.
Different Types Of Overhead Cranes You Should Consider
Before looking at the main difference between a single and double overhead girder overhead crane, let’s look at the different types of cranes you can purchase. There are so many variants including container cranes which are the ones that you will see on a dock which utilize horizontal gantry rails, and also cantilever supporting beams, which can handle incredible amounts of weight. There is also the full gantry crane which will have to supporting beams that are equal in size on either end of the beam up above. It is designed to handle a substantial amount of torque which can be created by very heavy loads, similar to those that are used in Belfast and in China to lift well over 1000 tons. Finally, there are workstation and rubber tired gantry cranes which are very large as well. However, if you are just looking at one that can lift anywhere from five tons to twenty tons, you simply need to focus on whether or not you need a single or double girder gantry crane.
Why A Single Girder Overhead Crane Is Often Enough
These are often enough for most businesses because they are capable of lifting between 5 and 10 tons. They can support that much weight, and even if the hoist is designed for a larger amount because it is either pneumonic or hydraulically powered, it’s still good to know that, for your business, this single girder design will be safe to use. If you are lifting more than that, the double girder design is often recommended because it will be able to support significantly more weight. Otherwise, you can save money, and also a substantial amount of time in the construction of this crane, if you decide to go with a single girder overhead crane instead.
Now that you know the difference between these two different styles of cranes, you can choose one that will fit your business. Most companies that have one inside do not often need to lift more than 10 tons, which makes the single girder gantry crane the best one to choose. Additionally, they can be installed very quickly and you can also save money because there are fewer components to this particular type of crane. It is simply the best choice for small to medium size businesses that are moving different types of merchandise that are relatively light in comparison to what double gantry cranes are typically moving.
