Selecting a type of bridge crane can be a difficult choice, in fact in most situations you will need more than one type to complete a task. The reason is each product has its own advantages and disadvantages, so keeping a constant balance is important. Just like most technologies there are standard models and premium models. The standard models have a lower price, but also have reduced abilities. The premium models have a higher price, but have an increase in features. The choice depends on funds available and what problem needs to be solved. The diversity of products available provides numerous solutions to problems faced in the industrial and manufacturing industries.
Single Girder Bridge Crane
History: In the late 1800’s the first ever electric overhead crane was developed, which replaced the previous mass produced (steam powered) crane. From that time until now, there have been significant advancements, which include numerous different models available, as opposed to only having one. The models have become safer and have an incredibly high lifting capacity, objects which could never be lifted, can finally be lifted. Efficiency has reached an all-time high and the world has abundance of products from many different manufacturers.
The choices are numerous, which has been made possible from the invention of the overhead crane, known as the bridge crane. The single girder crane can be considered the signature type of bridge crane available in the market, and can fit a wide range of different needs. It is also more affordably priced than many other types of bridge cranes, and their installation is much easier than double girder bridge cranes.
The single girder bridge crane has many advantages that make it a great choice for any industrial/manufacturing company.
- It’s the most economical choice in comparison to other types
- The hook weight is reduced because the girder is above the hoist
- Easy to maintain and install
- Has a lifting capacity between 10 tons to 20 tons
- Available in top running and under running
- Its light weight
- Lower production cost in comparison to other models
- Life expectancy of the beam is limited in comparison to other types
- Mechanical components are less durable in comparison to other types
- Hard to incorporate special features
- Limited load capacity in comparison to other types
- Limited span in comparison to other types
The details show the advantages and disadvantages of single girder bride cranes. They are smaller and cheaper to use and can greatly reduce production costs, but for certain problems they are not the solution. There may be a need for a double girder bridge crane, which has virtually a limitless lifting and span capacity, but has a significantly higher price. The choice can be difficult because different sections of manufacturing space need different type of bridge cranes. A shipyard needs a different product outside the ship yard in comparison to inside the ship yard. In many cases the need for both models may be the best solution, and the balance of choice can greatly reduce the production cost over the lifetime of the company.
