You may have seen different cranes lifting objects and placing them somewhere else. A gantry crane is almost similar to that. This crane is built on top of a gantry and it is mostly used to pick up automobile engines from the cars. Gantry cranes are also known as portal cranes. Their size can vary from full-sized gantry cranes to small shop cranes. In fact, their weight-lifting capacity also depends on their size. Some of the common gantry cranes along with their capacity are given below:
• Full gantry crane (Grúa en portico completa)
These are the biggest of the gantry cranes and they are built to carry massive items such as the engines of ships. One of the advantages of this crane is that it can be used to carry enormously heavy objects and comparatively lesser heavy objects. Full gantry cranes are available in various capacities but the highest ton capacity that has been recorded to date is 22,000 ton. The crane has a rather complicated system that is full of cables (cables) and several attachments. All these things help to keep the crane together and assist when heavy loads are being picked.
• Portable gantry crane
As you can understand from the name, a portable gantry crane is much smaller compared to a full gantry crane. These are used to lift smaller items and transfer them to the desired location. The maximum capacity that these cranes may have is usually less than 10 tons. So, you can understand the difference between the capacity of a full gantry crane (Capacidad de carga de portico grua) and a portable one. The system of this crane is not as complicated as the full gantry. There is an enclosed track that is equipped to the portable gantry crane. While others use the I-beam, this one manages to do the job with the help of the enclosed track.
• Ship-to-shore gantry crane (Grúa para contenedores)
A very common gantry crane is the ship-to-shore gantry crane. You will find them at various container terminals that are used to load and offload containers into a ship. The size of the crane will vary according to the type of object that is being loaded or unloaded. One of the best things about this gantry crane is its mechanism. There are two rails on which this gantry crane will operate. In fact, depending on the work that is done, the rails can be located along the waterside or on the landside. These cranes can be used with other cranes to increase the overall efficiency of the job. When a couple of ship-to-shore gantry cranes work together in tandem, they can load a full ship within a few minutes. The capacity of these cranes can vary from 1000 tons to over 8000 and even 10000 tons. If you want to know more, please click http://gruaportico.cl/capacidad-de-carga-de-grua-portico/
