A company that utilizes an electric hoist is going to be one that needs to lift heavy weights. Although there are portable ones that are available for shops and some indoor settings, if it is for an industrial crane, they need to lift a lot of weight. Some of the largest in the world are capable of lifting hundreds of tons, something that they must do on a regular basis. However, you may see some of them only using a single girder mechanism and you might wonder why this is the case.
Single Girder Versus Double Girder
When talking about the girder on a crane, such as a gantry crane, it is the overhead beam (viga) that goes across. Gantry cranes, for example, can have single or double girders and the primary difference is how much weight they are going to lift. If you have containers that are coming off of ships, and you have a gantry crane set up with the trolley, if the span between the ship and the dock is not very much, a single girder is going to be just fine. However, if you are lifting extremely heavy products, even if you are only moving them slightly on the trolley, a double girder system is going to be necessary to sustain the weight in order to prevent the collapse of the entire gantry crane. Even worse, you could be using the wrong hoist, or a type of wire cable that is simply not strong enough. You need to compare the different prices for the single and double girder cranes, and also look at the merchandise that you were moving regularly, to determine if the single girder train will be better for you.
Where Can You Get Excellent Deals On These?
It’s very easy to get exceptional deals. There are some companies in China that sell these (algunas empresas en China que venden estos) all the time. They are experts in this industry and will be able to tell you whether or not a single girder crane is going to be enough for the type of work that you do. If it needs to be a double gantry crane, for example, they will be able to direct you to the best product that they have available. These cranes from the Orient are some of the best in the world, capable of lifting well over 1000 tons working in tandem with multiple cranes, and therefore they are certainly experts in this industry.
When you decide to purchase an electric hoist with a single girder mechanism, one that is for industrial purposes, you can get away with a single girder crane. The only time that a double girder crane is absolutely necessary is when you are lifting 100 ton weights all day long which could compromise a single girder gantry crane system. Just remember that doing this research in advance can save you a substantial amount of money. Although you could upgrade, or by another one, that would be a waste of money. Make sure that you are purchasing a single girder mechanism that is going to work for your particular industrial business, and you can start generating more productivity with this product.
