Cantilever gantry crane is very popular in lifting industry. It has many advantages, such as simple structure, light weight, short manufacturing cycle, thus cantilever gantry is widely used for lifting and transporting material in open storage yard, station, construction site, industrial and mining enterprise. With cantilever, gantry crane can span its working area and improve working efficiency. Cantilever crane has two types, crane with single cantilever, and crane with double cantilevers. Ellsen Company, one of professional gantry crane suppliers, produces cost-effective cantilever gantry with advanced technology, reasonable design and safety protection devices.
What are cantilever gantry crane types?
Classification according to the number of cantilever, it has two types, crane with one cantilever, and crane with two cantilevers. Both of two types have its own features, and can be used together with electric hoists, customers can choose suitable one based on practical working condition. Compared with double cantilever gantry, single cantilever gantry has smaller size and lighter weight, and is easier to operate and maintain. The double one has larger loading capacity, and can load more material at one time. For frequent and small lifting work, single cantilever gantry is better while double cantilever adapts more to heavy duty work.
Classification according to girder structure, it has three types, truss type, box type and castellated beam. Truss girder is welded by angle steel or I beam steel. It has advantages of low cost, light weight and good anti-wind. Thus it is suitable for places with low working class and small loading. The box type girder is welded by steel plate, it has high security and great rigidity. It is used for heavy duty lifting work. Castellated beam has both features of truss type and box type, and it has strong rigidity, small deflection and reliable performance. It is suitable for places with frequent and large loading work.

How to buy a cost-effective cantilever gantry crane?
The installation of a gantry crane can be one of the best choices for any business that is lifting large numbers of containers or pallets which are extremely heavy. Instead of using forklifts, and multiple workers who could actually get hurt during the process, you can increase your safety rating and production levels by installing one of these cranes. These can be either extremely large, used on shipping yards, or it can be used inside of the facility in order to move smaller types of merchandise from one location to the other. There is one that is called a cantilever gantry crane which is becoming more popular because of the way that it works.
What is a cantilever gantry crane?
In the construction of a gantry crane, you are going to have your supporting beams that will handle the weight which are either installed independently, or that will use portions of the supporting structure within a warehouse setting. The girders up above will move back and forth, attached to a hoist, which is how the merchandise can be moved up and down. The combination of all of this will allow the operator to lift and move merchandise from one destination to another, but there is one other factor to consider. If you are using a cantilever frame, you are adding extra support for the trolley which is why moves back and forth, allowing the entire apparatus to have more stability.
Where can you find these for sale?
The place where you purchase these cantilever gantry cranes will depend upon what you need one for. You will have to decide if you want a traveling gantry crane that is used along the bridge or runway of the crane construction, or if you are going to use one that is traversing which allows the trolley to go from one end to the other. If you are using a trolley, then this is where the cantilever construction will come in handy because it will help support the trolley as it moves. You can find multiple companies overseas that produce these for a minimal amount where labor and materials are much less expensive, utilized by companies that have been building these gantry cranes for many decades.
How long will it take to install it?
The speed at which it is installed depends on the construction itself. If you are going to have new supporting post put in, this will take additional time. The size of the base plates which hold the supporting post in place can also contribute to a little more time to get everything just right. Once done, they will have to weld the truss into place on either end, and then installed the chain and hoist over the main moving beam. This is where you will use a cantilever support system to make sure that it is as stable as possible, helping you to lift more numerous items without any safety or production issues.
These are very unique gantry cranes which can provide additional support. They do cost a little bit more, but once they are installed, you will see the benefit of owning one. They are designed to maintain the integrity of the entire apparatus, especially if you are moving things many times per day. It’s also useful with heavier items, making sure that the hoist is always stabilized using this cantilever frame.
What are the prices of cantilever gantry crane?
When the owner of a shipping yard or dock starts to look for a cantilever gantry crane, they are going to be searching for one that is well-designed. These cranes are responsible for moving product from ships to the dock, and vice versa, as well as helping to load trucks that may be leaving with that product. This type of crane comes with cantilevers which are going to increase the ability of that crane, and the hoists that are used, to lift much more efficiently. The other benefit is that it will protect the legs of the machine, specifically from deformation from to much pressure, and is also capable of increasing the amount of traveling distance when handling virtually any type of product.
Why you might need to purchase one
The primary reason that people will consider the purchase of a brand-new cantilever gantry crane is they are either starting a new business, or their existing one is no longer functioning. They may make the mistake of getting one from a dealer in their area that may have a used one for sale, but they are always going to be better off with a brand-new model. The amount of time that it takes to create one of these can go on for several weeks, if not months, depending upon its size. There is the delivery time, but once it is set up and fully operational, you will then be able to determine how much it is able to really lift.
How much can they lift?
These cranes are actually very powerful. They have the capacity to handle loads of 200 tons or more. They are also extremely strong, allowing the crane to be built with a 35 m span which shows how well-designed these actually are. As far as lifting height, they will go up to 18 m, and can lift roughly 12 m every minute. The crane traveling speed is also worth noting, traveling 45 m for every 60 seconds.
Technical data on these cantilever gantry cranes
When you start to look at the data on these cranes, it’s a little different from regular gantry cranes. For example, it will depict the track type, trolley speed, and the work duty of the crane. Almost all of them will list the capacity which is how much weight they can actually sustain. The same is true for span, height, and the lifting speed. They are also economical, as long as you are purchasing them from a major manufacturer. There is a lot of construction and steel that is used. They are designed to handle extremely heavy weights, so when you do place your order, it may take them quite some time to make it to your specifications, and then ensure that it is capable of sustaining and moving the enormous amount of weight that you will be moving regularly.
The prices on gantry cranes can be tens of thousands of dollars, sometimes hundreds of thousands of dollars, depending upon their size and capabilities. For a typical cantilever gantry crane, you are probably going to spend a minimum of $100,000 because of the size of the crane and its capabilities.
