There are some important things that you will want to know about double-girder gantry cranes before deciding if you want to purchase one for your business. Once you know more about their basic design and about how they function, you should be able to get a much clearer picture of whether or not one of these cranes will help you achieve your goals.
Gantry cranes usually either feature a single-girder or double-girder design. The difference between the two has to do with the number of girders that span the gap between the legs of the crane. A single-girder crane has one girder connecting the legs, while a double-girder crane has two parallel girders spanning the distance between the legs. https://aicranemachine.com/
Typically, with a double-girder design, the trolley runs on top of the girders, with the hook hanging down between. In some cases, the trolley may also be mounted directly between the girders. With either of these designs, the hook height is generally higher than with a single-girder crane. That means that double-girder models provide more overhead clearance and are a better choice for rooms with low ceilings.
Another area where double-girder gantry cranes shine is in their ability to lift heavy loads. These cranes usually have a higher weight capacity than single-girder cranes, making them ideal for medium or heavy-duty lifting.
You rarely will see a double girder crane that has a lower lifting capacity than 10 tons. Many of them are capable of lifting hundreds of tons of weight. The reason for the high lifting capacity has to do with how the weight is distributed between the two girders.
If you are on the fence about whether a single-girder crane or double-girder design will work best for your business, consider reaching out to a crane manufacturer. They can send a company representative to your location to inspect your building in person. Based on the design of your building and the types of loads that you deal with, they can then recommend the perfect type of crane for your situation.
Getting an expert’s opinion is always a good idea when you are investing in a high-dollar piece of equipment for your company. Instead of trying to guess which type of crane is the best choice, it makes sense to get guidance from someone who really knows what they are talking about.
The two main things that you want to know about double-girder gantry cranes is that they generally have a higher hook height than single girder cranes and they frequently have a higher lifting capacity. Since the hook can be pulled up between the girders, loads can be lifted higher off of the ground, which is a good thing if you are in a building with low overhead clearance.
The additional lifting capacity can also be beneficial if you need to move loads that are anywhere in the medium to heavy range in terms of their weight. The best way to find the perfect crane for your business is by talking to a company representative from one of the top crane manufacturers.
