If you are planning to buy a single girder overhead crane, there are a few things you need to keep in mind in order to get the best value for your money. Even though all the single girder overhead cranes might look the same to an untrained eye, there are a few differences that have a major impact on their overall efficiency and safety. Here is what you need to know about making the right choice.
Capacity
You must be aware that these cranes are sold in a variety of capacities. As far as the single girder cranes are concerned, these are typically rated for a capacity of up to 16 tons(grua viajera de 16 toneladas). If you plan to lift loads that are heavier then 16 tons, it is better to go for a double girder crane. It is also important to keep in mind that the rated weight capacity is typically the maximum weight that can be safely lifted using that crane.
Span Length
One of the reasons buyers prefer a single girder crane is that it is one of the most cost-effective solutions for moving load on a factory floor or in a warehouse. Since this type of crane uses a single girder, it is much cheaper as compared to a double girder crane or other alternatives. However, it also means that these cranes have a limited span.
Crane Classification
Anyone who has anything to do with overhead cranes knows that there are different classifications for different types of cranes. These are typically based on the number of cycles per hour as well as the utilization of the rated capacity. These classifications range from class A to class F. Class A refers to the classification where the cranes are used infrequently whereas class F refers to classification where cranes are required to handle loads close to the rated capacity and on a continuous basis under severe conditions such as high temperatures.
Customization Options
A single girder crane(grua viajera monopuente) is not exactly known for customization but there are manufacturers out there that can help you customize your order, as per your requirements. However, these customization options are not offered by every manufacturer out there and this is why, it is important for you to ensure that the manufacturer you are planning to choose is able to customize as per your requirements.
Reliability
You shouldn’t have to worry about the reliability or safety of the crane(fiabilidad o seguridad de la grúa). Everybody assumes that the crane is going to be reliable but you should know that stresses build up over time and a crane that could safely lift a particular weight might no longer remain safe for that particular load capacity after a few months or years of use. This is why, it is important to choose a manufacturer who is known for their reliability and high quality of products. Do not choose a company only because they are offering a cheaper alternative. Keep in mind that any kind of mishap with the overhead crane could lead to huge losses.
Overall, a single girder overhead crane is one of the most efficient and cost-effective ways to move load in warehouses and factory floors. However, not all the overhead cranes out there are similar in terms of efficiency and performance levels as well as reliability. This is why, you need to keep the above-mentioned tips in mind when buying a single girder crane in order to get the best return on your investment.
