Single Girder Crane
The single girder crane system's rectangular work area offers the greatest degree of flexibility for all kinds of manufacturing. The single girder crane design is the best option for many uses, despite its capacity and span limitations. It also offers a number of benefits.
Yuantai single girder cranes are:
- Cost effective
- For rectangular working areas, large hook coverage
- Of high quality and longer services life
- Easy production and fast delivery
- Simple structure and easy installation
- User-friendly
Single girder cranes can help with a variety of lifting and transporting tasks. When properly planned, they will increase output and offer the perfect answer for operations and facilities that require a light to medium duty crane but have limited floor and overhead space.
A single girder beam, also known as a bridge, spans the width of the structure to form the single girder crane. In order to elevate or lower the load, a hoist and hook are placed by a trolley that travels horizontally along the bridge. Based on crane structures, the single girder cranes can be grouped into single girder overhead crane and single girder gantry crane.
Double girder crane
Double girder cranes doubles your efficiency for heavier loads handling. The triangular construction of a double girder crane system guarantees stable operations of loads up to 320 ton.
With a double girder crane system you can:
- Operated in application with heavy duty
- Cover an entire work space. with 3 dimensions of movement.
- Lift up to 320 ton
- Have a bridge span of up to 31 m or meters
The two girder cranes are usually constructed in box girder designs for provided more streigth and reliability for heavy loads and heavy duty applications. The box structured double girder cranes are driven by an electric motor, making operation just as simple. The loads are too heavy to be handled manually when handling loads up to 320 tons, so a safe and steady operation can only be accomplished with a double girder crane system that is provided with engine operation. Many times, a motor powers both the hoist and the crane bridge movement.
To achieve their maximum potential, the double girder cranes must be used in conjunction with a motorized hoist system, such as the electric chain hoist and electric wire rope hosit. The motorized trolleys typically come with two speed choices, but a frequency converter are also available based on requirement. All in all, the general operations of double girder cranes is equally quick, quiet, smooth, and secure.
Overhead crane single girder vs. Double girder
Based on crane structures, the overhead crane also can be grouped into top running crane and underhung crane.In the following, the single girder top running and under hung overhead crane, and double girder top running and underhung cranes are presented for for your refernece.
Top running single girder crane
A top running single girder crane is a particular style of overhead crane, also known as a top running bridge crane. With top running design, the single girder crane has its bridge spans on the top or runway rails, and the hoist suspended on the lower part of overhead crane girder. The capacity of a top running single girder overhead crane is 1- 20 ton, and can be up to 32 ton with processed crane design.
The Top Running Single Girder Cranes are made to help with a variety of lifting and moving chores, increasing your daily productivity and overall success.
Top running double girder crane
As a type of overhead crane, or bridge crane, the top running double girder cranes are consists of a double girder runway equipped with a traveling bridge between supported points within a structure. An electric hoist, or hoist trolley are used as the lifting system of double girder crane, which travels on the top and along the bridge.
Top Running Double Girder Cranes carry the bulk of the heavy lifting. With spans of up to 31 meters ’ and capacity to 320 Tons.
The top running double girder cranes are our most powerful solution for material handling,which are widely used in diversified application and environment with the features:
- Best for heavy service duty load handling.
- Single or multi crane hoists for loads handling available.
- Maximum design flexibility
Underhung overhead crane single girder & double girder
Underhung single girder crane
For uses that demand the greatest hook coverage area, the Under Running Single Girder Crane is the ideal option. The undersling single girder cranes may be suspended from a separate frame system or supported by the rafters or primary frames of the building. The under running single girder crane is capable of 10 Ton.
Features of single girder crane with underhung crane design
Maximizes floor coverage, reduces the size of the support columns, and allows for the incorporation of different crane hoist brands.
Underhung double girder crane
Underhung Double Girder Cranes are the best option for uses that call for more headroom beneath the runways. Runways can be mounted on the ceiling or suspended from the structure. With double girder design, the low headroom underhung crane can make use of the runway's depth. Larger spans and greater capabilities are possible with double girder underhung cranes.
The capacity of double girder underhung cranes are 20 ton
Gantry crane single girder vs. Double girder
Based on structrues, the gantry cranes can be grouped into double leg gantry crane also called full gantry crane and single leg gantry crane or semi gantry crane. In the following the featrures of single girder double leg and singl leg gantry crane, and ouble girder double leg and single leg gantry cranes are presented for your refernece.
Double leg gantry crane single girder vs. Double girder
Double leg full gantry crane single girder
A gantry crane with a single girder/beam construction is referred to as a single girder gantry crane. Typically, the lifting device consists of a crane traveling along a rail track attached to the ground or floor and a wire rope hoist moving along a single girder. Steel section or welded box girder or lattice girder gantry cranes are used to create the frames for single-girder gantry cranes. The single girder crane was constructed under stringent FEM/DIN guidelines.
Double leg full gantry crane double girder
The double beam/girder structured gantry crane is the double girder gantry crane with double girder hoist and open winch trolley running on the girders as the lifting system. For material handling, the gantry crane moves to various locations along rail lines. Cantilevers that are outstretched at the main beam's two extremities can provide a wider working area.
Single leg gantry crane single girder vs. Double girder
Single leg gantry crane single girder
The single leg gantry crane is also called "Semi-Goliath Crane" which minimizes floor area intrusion. It consists of the a top running crane girder and one supporting leg running .
The single girder semi gantry crane offers the following advantages for your application:
- Makes the most of available floor area while reducing risks and traffic-related problems.
- An answer that is application-specific.
- A less prevalent but very powerful type of overhead crane.
- A number of hoist models may be used.
Single leg gantry crane double girder
Double girder semi gantry crane is a special kind of overhead crane. This double girder semi-gantry crane only has one side supported by A frame leg, while the other side is mostly supported and running or runways supported by walls of workshop/warehouse.
The double beam semi-gantry crane is primarily used to move objects outside. Under the main girder, the A-type supporting legs travel on the ground track.

How to select for your application, single girder crane or double girder crane ?
Generally, the selection of single girder and double girder cranes are mainly decided by your lifting requirements and application conditions. If you need to move heavy loads or have a high hook height, a double girder is a superior option, but it will cost you more up front. A single girder crane might be able to satisfy your requirements at a lower initial cost if you have relatively lighter loads or space restrictions.
Pros of Single Girder Crane
- Less expensive due to less material and easy and faster installation
- Most economical light-to-medium-duty hoist crane choice
- Lower load or wheel pressure on the building structure
- Better hook approach for trolley and bridge travel
- Easier to install, service, and maintain
- Better solution if the your facility has adequate headroom.
Cons of Single Girder Crane
- Crane Hoist is usually suspended under the lower parts of bridge girder so reduced hook height
- The under-running trolley can lead to premature wear on the beam
- Special features like service walks and lights can be expensive or hard to add
- Lower liftin capacity capacity
- Shorter crane span
Pros of Double Girder Crane
- Larger capacity to handle heavier load weight
- Longer span
- Greater hook height
- No limits on how far it can span or capacity
- Easy installation of catwalks, cabs, or lights
- Available for both indoors or outdoor use
- Easy to maintain
Cons of Double Girder Crane
- More expensive because of two beams needs more material, and added structural support, and more complex components
- Higher set-up cost
- Lessened hook approach for trolley or bridge travel
