Although these are not the largest, 20 ton gantry cranes are capable of lifting a substantial amount of weight. They are usually positioned outside. For example, when you have a BMG double girder gantry crane, especially those that are semi-cranes, these will be attached to the outside building. This is a classification or type of 20 ton gantry crane that is quite common on peers, or it may be adjacent to a warehouse. They can have a span length of up to 35 m which makes it possible for the trolley to load and unload everything that is below it.
L Single Girder Gantry Cranes
These cranes are designed in a very different way. They are going to have two separate bases. Instead of the typical for, they just have something that is very wide at the bottom which will prevent them from falling over. You can walk on the top of these, and they can be up to 35 m. Some of the base units lift only 20 tons. These are certainly designed for the outside, similar to the MG double girder gantry cranes that are in this classification.
U Model Double Girder Gantry Cranes
These are one of the largest that you will see, with the exception of a truss gantry crane. In fact, if you are in a high wind area, the truss crane is probably the one that you will want to install. They are very similar in design, and also in height. The primary difference is that there are two girders on this one, and they are going to use solid pieces of metal. Even if there is a lot of wind, they are so heavy that it is unlikely to be affected. These are also going to roll, making it possible to maneuver it to wherever it needs to go to lift and lower objects.

Why You Need To Know These Classifications
The main reason that you need to know all of this is because you may not need one particular crane, but you will need another. That is because of its size, power, lifting capacity, or the span of the unit. If you need one that is freestanding, or if you need one that will be adjacent to your warehouse, all of these are available. It just depends on how much room you have, and what you are lifting on a daily basis. These are factors to consider when you’re making this type of purchase.
Whether you get a single or double girder gantry crane, or one that is portable, these are all different classifications. Rail mounted gantry cranes, as well as rubber tired gantry cranes, are almost always designed for the outside. The classification of the crane that you choose is based upon its name, what it does, and how much it can lift. In the case of the 20 ton cranes that you will want to purchase, just make sure that they are the proper classification for the type of work you are in. This will allow you to increase your production levels and start improving your business. To learn more, you can visit our website http://gantrycranesmanufacturer.com/
