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.

How far can they take the material?

The distance that it will take material can be up to 200 feet away they are almost always used in a workstation area. Their capacity usually starts at about thousand pounds, and goes up to 5 tons, but they can be designed for much more than that. Additionally, the monobox construction makes it possible for 10 ton single girder trains to successfully move most heavy items, having a span of about 60 to 80 feet.

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.

Structure of a single girder gantry crane

Understanding how gantry cranes work is far easier when you understand the components that go into their design. By taking a closer look at the structure of a single girder gantry crane, you can get a clearer picture of exactly how these cranes operate.

The easiest way to explain how these cranes are put together is to start with the largest sections of the crane. These cranes have a single girder that is connected on either side by two large legs. Together, the girder and the legs form a structure that looks somewhat like a bridge.

With a single girder gantry crane, there is only one girder connecting the legs. This is in contrast to a double girder crane where there are two girders or beams that connect the legs.

At the bottom of each leg is a set of wheels. Depending on the design of the crane, these can either be hard rubber wheels that are designed to roll over smooth surfaces such as asphalt or concrete or they can be metal wheels that are designed to run on tracks in much the same way as a train.

Attached to the girder is a device known as a trolley. The trolley is usually controlled by electricity and moves back and forth along the entire length of the girder on a set of small wheels. On extremely large cranes, the operator of the crane may actually ride inside of the trolley, controlling the crane from within a glass enclosed cab. On smaller cranes, however, the operator controls the crane using a handheld remote or a stationary control panel next to the crane.

The final component of the crane is the hoist. This device hangs down from the trolley. It has a hook, strap, or magnet on the end that is attached to whatever object is being lifted. The design of the hoist uses a series of special gears to minimize the amount of force that is required to lift these objects off the ground.

To operate the crane, the crane operator first securely attaches the hoist to whatever object is being moved. Next, using the control panel or remote control, they raise the load off the ground with the hoist. Once it is high enough in the air, they then move the trolley along the girder to the correct position.

If the item is just being moved along the length of the beam, they then lower it back down to the ground. On the other hand, if it is being moved to a completely different area, they may then move the entire crane using the wheels attached to the legs so that they can get the object in the correct position before lowering it back down.

Now that you understand the basic structure of a single girder gantry crane, it should be far easier to grasp how they work. Although these cranes are simple in terms of their overall design, they are extremely beneficial any time there are heavy objects that need to be lifted or moved.
