Setting up a manufacturing or fabrication unit involves a lot of effort – from finding the space where the unit will sit to ensuring that there is a team in place to ensure that all the work gets completed, well within time, each time. In addition, if you are engaged in larger machines or equipment, you will also need to have a system in place that will allow you to move all these parts with ease and efficiency.
It is at a time like this that you will require assistance in the form of cranes, because many a times, manual effort will prove ineffective and you will need help from heavy machines. This would be the time when you would find the need to invest in a crane, but before you purchase the first crane that you set your eyes on, there are some things that you need to know. For starters, you need to know that there are two main types of cranes – single girder cranes and double girder cranes. Depending on what type of unit you have or what your particular requirement is, you will need to choose a crane.
Before making the all-important choice, it is important to understand the basic features of both single and double girder cranes, and what makes them different from each other.
The single girder crane is most often used in machinery manufacturing industries, the petroleum, petrochemical and metallurgical industries, ports, railways, aviation and power stations. These cranes have the widest scope of usage, and this is so because the crane has a reasonably smaller size and requires lower headroom. In addition, it can handle light weight objects while requiring smaller wheel pressure. Being a single girder, there is only a single direction operation possible, however, you can choose from cable operation or wireless remote control methods. This is a good choice for people who have a slight space constraint and want to use the available space in the most efficient manner possible. This is also the more cost effective option, which means that it is the ideal choice for smaller industries.
Moving on to the double girder crane – an important machine in the modern industrial world, this type of crane is used for production as well as transportation. This type of crane finds usage in industries, mining, iron, steel and logistics. You will also get to see this type of crane at ports, railways terminals and commercial airports. If you are looking to lift heavy products to a greater height, then this would be the ideal choice for you, because the hoist would be placed between the cross girders, offering better assurance. While the single girder crane would be used for light duty loads and shorter operation times, the double girder crane can be used for heavier loads and for longer stretches of time. However, it is important to remember that a double girder crane will cost you much more than a single girder one.
