A semi-gantry crane is, for all practical purposes, a gantry crane where one of the edges rests on a rail attached to the structure and the other side rests on the usual A-shaped leg which runs on the rails attached to the surface. A semi-gantry crane is a popular alternative to bridge cranes. Even though it is pretty popular as an outdoor solution, it is also widely used indoors. In short, it’s a flexible solution that can be used both outdoors and indoors.
These are available in a wide range of lifting capacities. You’ll find these cranes in shipyards, rail yards and other places where a huge amount of weight needs to be lifted and moved safely. As far as choosing a particular semi-gantry(semi portico) crane is concerned, there are a couple of factors you need to take into account in order to get the best value for your money.
One of the first things you need to look at is the durability of the semi-gantry crane. After all, the crane is going to be used for lifting and moving huge amounts of weight and you do not want it to result in any kind of accident. Therefore, durability is the most important factor you should consider to make sure you are able to use it without any issues for many years to come. One of the best ways to check the durability is to ask the manufacturers about the materials used in making the crane and this will give you some idea about the durability and reliability(durabilidad y confiabilidad) of that particular model. In addition, you should also check the reputation of the company selling the crane to make sure they are known for selling only reliable and durable products.
The next thing you need to check is the capacity of the crane. Needless to say, the capacity will be decided by your actual requirements. Don’t just focus on your immediate requirements but also think of the near future. However, do not buy too much capacity as it will only result in idle capital which is something, nobody wants. Therefore, only buy capacity you are likely to use in the near future but don’t buy too much capacity as it will only lead to inefficiency and loss in productivity.
You also have the option of buying powered and non-powered cranes. Powered cranes help in reducing operator fatigue and also help in enhancing material handling efficiency. On the other hand, non-powered cranes are an excellent solution for material handling when it comes to cost effectiveness. Both have their own advantages and have their own specific applications. The choice among these will depend on your budget, your specific requirements as well as various other considerations.
As mentioned in the beginning, a semi-gantry crane is used for lifting and moving heavy weights. Moving such weights always creates conditions for accidents and one of the ways to prevent any such unfortunate accident from happening is to invest in a crane that is easy to use and economical. In short, pay attention to the gantry crane(grua portico) design and make sure the operator can handle things easily. The controls should be intuitive and shouldn’t put unnecessary stress on the operator.
To conclude, a semi-gantry crane is widely used in various applications for moving heavy loads. However, not all the semi-gantry cranes are the same. Pay attention to the above mentioned tips in order to choose the right type of semi-gantry crane.
