Single girder gantry crane is mainly used for transporting, loading, unloading material in outdoor yard, warehouse and other places. Its working class has light, medium and heavy. The sling used for lifting loads is hook. There is also aiding slings. And electromagnetic sucker, motor grab can be matched as auxiliary sling. AIMIX Group, a professional gantry crane supplier, provides girder cranes with top quality and reasonable price. Except single girder crane, our company supplies double girder gantry and semi gantry crane.
What is single girder gantry crane?
This girder crane is mainly composed of bridge girder (main beam), four legs, lower cross beam, and gantry mechanism driving device, electric control and electric hoist.
The bridge girder is usually the box structure welded by steel plate. Under the main girder, there is setting I-steel track for electric hoist travelling. For outdoor gantry cranes with wide span, it is suitable to adopt truss structure welded by section steel. This kind of structure has many advantages, for example, good rigidity (especially horizontal stiffness), light weight, small wind area, and higher economic benefits. According to practical condition, the main girder is equipped with cantilever or not. For girder with wide span should be made by block. The girders and legs are connected by high strength bolts.
Gantry mechanism driving device
It usually adopts respective driving. Through a set of vertical reducer, driving motor and brake are connected and combined as a set of driving device. Gantry cranes for outdoor use, there is setting rail clamp and anchor to ensure the ability of anti-wind and anti-sliding. When the crane doesn’t work, the clamp must be clamped on the rail, and the anchor pin is locked into the anchor hole. In this way, it can avoid serious accidents.
How does electric hoist of single gantry work?
Electric hoist on single girder gantry crane can lift material and travel horizontally. There are buffers on the ends of main girder, which can ensure limited travelling location of hoist. There is lifting limited switch in lifting mechanism. It can limit lifting height. When the goods rise to the highest position, the limited switch works, cut off electric current of lifting motor, so that it can limit the lifting position. Then lifting mechanism can only travel on the opposite direction.
The ways of gantry crane operation
Gantry crane operation has three ways, ground wire control (button box control), wireless control, room control. For ground control, the rail of movable button box and conductive cable slide are set respectively. In this way, they can travel alone and they are not influenced by electric hoist position. For room control, there is setting ladder platform on the legs to ensure entering the cabin safely and conveniently.

What are different types of single girder gantry cranes?
One of the most cost effective gantry cranes that you can install at your facility is a single girder gantry crane. There are many advantages to using this particular style, especially if you are in a warehouse setting. Larger gantry cranes which are designed for moving large containers from ships, or working on construction sites for skyscrapers and bridges, are much too large to fit in this type of facility. They can have a maximum load capability of about 20 tons, and can have a span of well over 100 feet.
What are the advantages to using one?
The main advantages to using one of these is that there is a low deadweight, offering much more headroom. It will use a model rail hoist designed for low headroom use, and is a very economical solution for those that use this with a span of less than 90 feet. Due to the fact there is only one girder, it has a much lower production cost than other gantry cranes that are substantially larger. It is also much less costly than when using a double girder model which uses two girders instead of one. Manufacturing time is faster, along with the speed at which it can be installed, primarily because it is using the existing structure in most cases for support. These can be used with many different types of businesses that are responsible for transporting and moving smaller items opposed to larger ones at construction sites.
Different types of single girder gantry cranes
The main differences and single girder gantry cranes is in the way that they move. There are traveling gantry cranes which means that the merchandise will move across the bridge or runway itself. If it is a traversing gantry crane, there is a mechanical gear or trolley that can be used to go from one end to the other. Both of these will use some type of hoist that will allow the merchandise to be lifted up, and brought back down, to specific areas within the facility.
The installation of one of these gantry cranes inside of your worksite, or wherever it happens to be installed, can improve your production levels. It will cost far less than any other gantry crane, yet will provide you with the capability to move items or pallets up to 10 tons in weight safely and securely. You can have these installed in under a week in some cases, and once you do, you will notice that it will be much easier for your workers to keep up with production and also improve overall safety at your facility.
