Industrial overhead cranes are used in many different settings, from factories to construction sites. These cranes help to move heavy loads from one place to another, making them an essential piece of equipment for many businesses. But how do overhead cranes work? Most overhead cranes consist of three main parts: the bridge, the trolley, and the hoist. The bridge supports the trolley, which is used to move the load back and forth. The hoist is mounted on the trolley and is used to lift the load up and down. Together, these three components enable the crane to operate safely and efficiently. But to make sure that everything runs smoothly, you must maintain the crane from time to time. Here’s a maintenance checklist that you can follow:
● It is critical to test the calibration on all indicators of the overhead crane(puente grúa industrial) on a regular basis. This includes load and boom angle indicators. Regular testing helps to prevent potential accidents that could occur if the indicators are not functioning properly.
● Before using an overhead crane, it is important to thoroughly inspect all of the crane’s components to ensure that they are in good working order. This includes checking the motion lever, brakes, and locking devices. The brakes should be examined for any signs of wear or damage, and the motion lever should be tested to ensure that it is working properly.
● The load moment indicator (LMI) or rated capacity indicator (RCI) of the overhead crane provides an indication of the status of the crane with respect to the rated load capacity. The accuracy of this indication must be checked at initial acceptance and periodically thereafter, in accordance with the manufacturer’s instructions. The check shall include, as a minimum, a comparison of the RCI or LMI reading with the actual load on the crane hoist(grua puente) line. If the accuracy check reveals an error greater than 2% of the full-scale reading, the RCI or LMI should be adjusted or replaced in accordance with the manufacturer’s instructions.
● Overhead cranes are used to move heavy loads, and their regular operation is essential for keeping production moving. For this reason, it is important that overhead cranes be inspected on a regular basis. This inspection should include a check for any loose or missing bolts, nuts or pins, as well as any cracked or distorted parts. If any of these issues are found, they should be addressed immediately to avoid potential problems down the road.
● To check the brakes, first, make sure that the power is off and that the crane is in neutral. Then, engage the brake on the bridge by pulling the lever or pressing the button. Next, engage the brake on the trolley motor by turning the handle clockwise. Finally, test the brakes by pulling on the rope or chain. If both brakes are functioning properly, then it is safe to start the overhead crane(puente grua monoviga).
Proper overhead crane maintenance is key to ensuring that your equipment operates safely and efficiently. By following the tips above, you can keep your crane in good condition and avoid costly repairs or replacements.
