Welcome to Henan Mine Crane Co.,Ltd.
When purchasing an overhead crane, it is a long-term purchase. So, many customers at first like to know the price of an overhead crane to see if it is within their budget. But, the lowest price does not necessarily mean the lowest cost in the long run. This is because a wrong choice of an overhead crane for your working needs can generate problems later on such as an too low lifting capacity, too much maintenance and even the high cost for replacement a crane.
The overhead crane choice between single girder overhead cranes and double girder overhead cranes depends on the specific working conditions that you have in your facility. Load weight, shop floor space, working height, and work frequency all need to be taken into account.
The key feature of the two types of cranes is the bridge structure. A single girder overhead crane has one main beam, whereas a double girder overhead crane has two main beams. A single girder crane is often used in standard workshops. Double girder cranes are more typical of the heavier industries.
When choosing a crane for your company first look at your daily operation. A repair workshop and a steel factory both can make use of an overhead crane. But the application can be so different from each other.
A single girder overhead crane is often selected by customers who require the simplest and most cost-effective lifting solution. A single girder crane has a lighter structure, requires less floor space and generally provides lower installation costs than a double girder overhead crane.
This means that a machinery workshop moving loads of 2-5 tons during normal operation of the workshop does not require a very heavy crane and Single Girder cranes can be cost-effective to purchase.
LD type single girder overhead crane is widely used in various fields, like factories, warehouses, workshops, and other places related to material handling in logistics. The crane consists of main beam, end carriages, electric hoists, electrical control systems and travelling mechanisms. Its design prioritizes stable operation, easy installation, flexible manipulation and convenient maintenance.
Double girder overhead cranes are heavy-duty industrial lifting systems designed for high-capacity applications, long spans, and frequent operation.
A simple example is a steel mill or mining workshop. In such establishments, a crane can be used for repeated lifting of heavy loads, possibly even over several shifts. A sturdier design would in this case result in greater working stability and a longer lifespan.
Compared to single girder overhead cranes Double girder overhead cranes have higher lifting capacity and are more efficient in operation. They are used in particularly heavy workload applications.
Single Girder vs Double Girder Overhead Crane Cost Comparison
The answer to this question is not that simple. First of all there is the price of the equipment, the installation work, the maintenance, and last but not least the production.
Single girder overhead cranes tend to have lower overhead crane cost due to their light structure, require less material and have less stress put on the building structure compared to double girder overhead cranes.
A double girder overhead crane is generally more expensive at the beginning, due to a stronger structure and more complex equipment configuration. In heavy production environments, however, higher initial investment can help to avoid capacity problems in the long run.
For example, a factory wanting to increase production within the next 3 years would not get a good return on investment for a crane which only meets the current requirement.
The duty cycle is another cost factor. The duty cycle describes the frequency with which a crane is used and the quantity of loads lifted. A crane that is only used from time to time is very different from a crane that is in operation around the clock on a production line.
A professional choice of a crane for professional use has to be based on more criteria like the lifting capacity, the working frequency as well as the operating conditions and not just on the purchase price of an overhead crane.
Choosing an overhead crane is like choosing any other production equipment. It has to fit the job and not necessarily be the one with the highest technical data.
Before requesting a quotation for a crane for your project, compile and prepare the basic information required to avoid any unnecessary costs and to design the crane more precisely.
First check out the hoist's lifting capacity, the span, and the lifting height.
Crane capacity for lifting is an important selection criteria. Span refers to the distance between the end of the runway rails. Lift height is important as it needs to allow for safe lifting within the workshop.
A typical warehouse with average material handling tasks would normally be served by a single girder overhead crane. In contrast, a factory that installs large pieces of equipment or even larger components may well require a double girder overhead crane.
Workshop environment. Consider indoor temperature, dust, outdoor use and special safety requirements before purchasing a crane.
In addition to the standard design of projects some of them need customized design of span, lifting height, special design for explosion proof, using variable frequency drive or intelligent control etc. Such options should be planned from the beginning of the project and not to be added as an afterthought for the installation.
When choosing a crane for lifting purposes in production it is not only important to tackle current problems but also to reserve sufficient clearance for future modifications in production.

Q1: Is a single girder overhead crane cheaper than a double girder overhead crane?
A: A single girder overhead crane is generally less expensive to purchase initially. It is used for light to medium duty lifting. A double girder overhead crane costs more but offers greater capacity for heavier work.
Q2: A single girder overhead crane is suitable for use in warehouses?
A: Yes. A single girder overhead crane is often used in warehouses, workshops, and other locations where heavy items are moved within a facility on a frequent basis. This type of overhead crane is best suited for lifting loads of average to low weight and height.
Q3: When to choose Double Girder Overhead Crane?
A: Higher lifting capacity, longer span, higher lifting height or more frequent operation.
Q4: Can overhead cranes be designed for specific projects?
A: Yes. Crane systems can be customized to design to meet specific requirements including capacity, span, height, work environment, control, and specific operating conditions.
