A gantry crane consists of a horizontal beam that is supported by legs that extend outward from each end. This type of crane is commonly used in shipyards, ports, and other industrial settings where heavy loads need to be lifted and moved. They can be operated manually or via remote control, and their size and lifting capacity can vary depending on the specific needs of the application. You can use gantry cranes to lift and move materials such as containers, steel beams, and machinery.
Working mechanism of a gantry crane
A gantry crane(gruas semiporticos) comes with an A-frame structure that moves along the rails or beams mounted on the frame. It is used for moving heavy loads from one place to another.
The working mechanism of a gantry crane is relatively simple. The crane has a trolley that runs along the rails or beams, and this trolley is connected to a pulley system. The pulley system has a cable that runs over a series of sheaves (pulleys). The cable is attached to the load that needs to be lifted, and as the trolley moves, the cable winds around the sheaves, lifting the load. When the load reaches its destination, the trolley is stopped and the load is lowered. Gantry cranes can be operated manually or with the help of an electric motor.
Using a gantry crane
Operating a gantry crane safely and effectively requires careful inspection of the crane(grúas pórtico sobre neumáticos) before each use. It is the duty of the operator to check all the hooks, controls, safety equipment, wire ropes, and other parts of the crane to ensure that everything is in good working order. If any problems are found, they must be fixed before the crane is used.
In addition to inspecting the hardware, the operator must also be familiar with the crane’s operating manual. The manual will provide information on how to operate the crane safely and efficiently. He should take the time to read and understand the manual before using the crane.
It is also important to pay close attention to the crane’s operation at all times. If you notice anything wrong, you should signal to stop using it immediately. There are a few different things that can cause a gantry crane to behave abnormally, such as incorrect rigging or overloaded lifting capacity. If you’re not sure what the problem is, it’s always better to err on the side of caution and call for help from a professional. Resources: https://aicrane.cl/tipo-de-grua-portico/
There is a bell that you can ring to send a signal to everyone. Apart from ringing the bell to send an alarm, here are a few more reasons why you may use it:
● If the weight is falling or rising suddenly.
● If the crane is not moving in the correct direction.
● When you see the trolley moving.
● If you see someone near the load.
● When the crane is reaching its destination.
Gantry cranes of AICRANE are an important part of many industrial and construction settings. By understanding the basics of crane operation, you can ensure that these machines are operated safely and effectively.
