Purchasing a double girder overhead crane can be a very expensive investment. Depending upon the size of the crane, and its overall capacity to lift cargo, they can become quite pricey. Many people will order these from countries outside of their own, attempting to get the best deal. What is most important is that the crane that you order cannot only lift the cargo but can do so in an efficient manner. As long as they are designed for the maximum amount of weight that you are going to lift daily, they will also be very safe for the workers at your facility. Here is some helpful information about double girder overhead cranes that you need to know in order to make the right purchase.
How Are These Cranes Constructed?
Assuming that these are gantry cranes, they are constructed in one of two ways. The most common way is that they will have two legs on each side, forming a triangle, that will provide the support. At the top will be a beam, or a girder, which is where the hoist and trolley will be located. If you have a single girder crane, these are not capable of lifting as much weight as those that have double girders.
Parameters To Consider When Ordering Your Crane
There are certain parameters that you always need to consider before placing an order for an overhead crane. The four most important factors will include the load capacity, lifting speed, lifting height, and the span length of the crane itself. The loading capacity simply references how much it is capable of lifting. This will depend upon the structure of the crane, and the electric or hydraulic motor that is providing the power. The lifting speed references how fast it will be able to lift cargo that is close to the maximum loading capacity. The lifting height is important for two reasons. First of all, it needs to be tall enough to lift extremely large objects, and if this is a semi gantry crane, it needs to be the right height so it is level with the building on the other side. Finally, the span length is important for a couple of reasons as well. First of all, if it is more narrow, it will be more stable. However, if your goal is to have trucks park in parallel or even trains, you will need to have this as wide as possible. This is why you must take measurements and provide information to the companies that make them if you need one that is a specific size for your business.
If you are able to do research on multiple manufacturers of cranes, you will almost always find three or four that look very promising. By providing them with this information on the dimensions and loading capacity of the crane that you want, they can give you a quote on how much it will cost. This is how you will be able to not only find the best business but also access the lowest prices in the industry.
