Bridge gantry crane mainly refers to girder crane, like single girder gantry crane, double girder crane, semi gantry crane. According to loading capacity, gantry bridge crane can be divided into two types, small crane and heavy lift crane. With advanced technology, professional experience, customized service, Our company, a reliable gantry cranes manufacturer, can design types of cranes with various tons, such as 1 ton, 2 ton, 5 ton, 15 ton, 30 ton. All cranes are carefully checked and packaged before selling. Thus our gantry cranes are very popular in hoisting industry.
How to choose suitable bridge gantry crane types?
Different working conditions need different types of crane, thus it is wise to choose suitable lifting gantry according to working class and practical requirement. Our company designs types of cranes to meet customers’ needs, such as small cranes, heavy lift cranes, industrial cranes, travelling crane, rail crane and so on. All our gantry cranes have safety device and perform well!
For working class, it includes light, medium and high class. Small gantry crane or portable gantry crane is suitable for light working class. It is widely used for light duty and frequent lifting work. With little size and tiny weight, it is convenient to operate, fast to move, flexible to travel. What’s more, the gantry crane cost is less than heavy duty gantry crane. Heavy lift crane is a better choice for loading and unloading large heavy deal! Industrial crane, electric crane, traveling crane, engine crane are all available. These our cranes can adapt to medium and high working class very well!
For specific requirement, we can design reasonable gantry crane structure. For example, if the crane is used to lift heavy goods for long distance outdoor, rail mounted gantry crane is good. The crane travels on the rail, which can achieve lifting material for distance and save energy and time, so as to raise working efficiency and improve working condition.
What are safety devices of gantry bridge crane?
Except quality and price, safety is another key factor customers care for. Security devices can protect operator’s safety, reduce accident and prolong service life of products. Our group produces cranes with complete safety protection devices, such as overload limiter, extreme position limiter, skew adjustment, display device and others.
What’s operator should accept professional training and utilize the crane correct! Every daily check work is also important for safety. Never neglect every factor related to crane safety!
The wide applications of bridge gantry cranes
When using a gantry crane, one that is either outside or inside, there are many applications for using this device. These are typically enormous, capable of lifting several hundred tons, or as little as 1000 pounds. They are designed not only lifting using the hoist and trolley, but they are also designed for moving merchandise from one location to another. If you are having a bridge crane installed, also called an overhead crane, you can find these and fabrication shops where automobiles are assembled, and also in areas where buildings are being constructed, showing how wide the application range is for these particular types of cranes.
The popularity of top running bridge cranes
A very common place to find bridge cranes is when you are going into a warehouse facility. You will see them up above, moving back and forth. If you see a single girder bridge crane, they typically lift up to 15 tons with the maximum span of about 60 feet. Single girder bridge cranes can easily lift 10 to 15 tons whereas double girder top running overhead cranes can go up to 25 tons. The larger the crane, the more that the operator will be able to lift which can actually contribute to higher production levels. The reason that the running bridge cranes are so popular is that it allows the merchandise to be not only lifted, but transitioned from one area of the facility to another. This will diminish the possibility of workers getting hurt that would otherwise have to manually move the merchandise using forklifts and other means.
Other applications for bridge gantry cranes
Some of the largest ones in the world are used at shipping docks, but they are most commonly used in the refinement of steel. You may go to a facility where metals such as aluminum or copper are being refined where the molten material cannot be in the presence of actual people, nor could it be lifted due to the incredible weight. They are used for the manufacturing process of not only metal, but with workstations where jib cranes are used, very common at a sawmill or any type of facility where large objects must be moved.
The installation process can take anywhere from a couple weeks to a month, depending upon their size. It also depends on how complex the crane actually is. If it is a single girder crane, or one with double girders, this can change the installation time quite a bit, especially when extra supporting beams need to be put in place if it cannot use the supporting structure of the building that it will be in. Other things to consider are the runway rails, trolley frames, and the type of hoist that is used on one of these cranes. They are designed to lift large amounts of weight, and in the case of those used within a facility, they must be able to move merchandise to specific locations to accelerate productivity at the workplace.
The basics of the bridge gantry crane
The bridge gantry crane is a staple in industrial situations and can handle huge loads of weight. You will find bridge gantry cranes in power stations, mills, factories and large construction sites. The shape of the crane resembles a bridge and it is made with five crucial parts. Read on to learn more about the bridge gantry crane and how to choose the right one for your operation.
The first part of the bridge gantry crane is the hoist. The hoist is what does the lifting. The hoist is attached to the bridge by a trolley. The trolley moves along the bridge and carries the load to the destination. The hoist can move up and down and it can move from side to side. These cranes can handle lifting tons of weight and they are heavy duty pieces of equipment.
The frame can be adjusted to longer or smaller distances and you can also change the angle of the trolley track. The crane is usually run on electricity, though there are hydraulic cranes and cranes that run on diesel. The bridge of the crane is supported by two legs that absorb all the weight of the crane.
When you are shopping for a crane, you need to determine if you want a light duty crane or a heavy duty crane. The light duty cranes are perfect for smaller loads, while the heavy duty cranes can handle the biggest loads you throw at them. Light duty cranes are best suited for loads under 20 tons, while the heavy duty crane can handle cargo up to 500 tons.
You must also consider the strength of the crane and what kind of girder system you want. The single girder system uses a single beam to support the runways and while it is lighter, it can’t support as much weight as the double girder crane. The extra girder on the double girder crane can absorb more weight and bring the lifting capacity up to 200 tons. If you are working in a large factory, the double girder crane is a good bet.
You need to think about where the crane is going to go and how much headroom you are going to have with the crane. This will inform whether you want to buy the top running bridge crane or the under hung crane. The under hung crane works well in situations where there is low headroom, while the top running crane works well when room is not an issue.
Before you order a crane, you need to know how much weight you are going to need to be lifting. This will help you decide the size of crane you are going to need. If you are going to be lifting smaller loads, then the light duty crane is going to be a good choice. The bridge gantry crane helps the production process go much smoother and easier. If you need to get your work done on time and on budget, consider the bridge gantry crane.
