The fault diagnosis and maintenance of overhead crane mainly include the following aspects: 1.Electrical fault: The electrical system of overhead crane is an important part of it. Common electrical faults include cable aging, poor contact, motor overload, etc. For these faults, first check whether the cable is damaged. If damaged, it needs to be replaced in time; secondly, check whether the contactor and relay are working properly. If there is a problem, they need to be repaired or replaced; in addition, check whether the load of the motor exceeds the rated load. If it exceeds, the load needs to be reduced or the motor needs to be replaced. 2.Mechanical fault: The mechanical part of the overhead crane is also prone to failure. Common mechanical faults include gear wear, bearing damage, brake failure, etc. For these faults, first check and clean the mechanical parts. If the gear is found to be severely worn, it needs to be replaced; secondly, check whether the bearing is working properly. If there is a problem, it needs to be lubricated or replaced; in addition, check whether the brake is flexible and reliable. If it fails, it needs to be repaired or replaced. 3.Operation problem: Operation…

In recent years, the field of overhead crane has experienced significant technological advancements. These innovations are designed to improve efficiency, safety and sustainability, making overhead crane more intelligent and versatile in various industrial applications. Here are a few key areas of technological innovation: 1.Automation and intelligent control One of the most transformative changes in overhead crane is the introduction of automation and intelligent control systems. Modern overhead crane are equipped with advanced sensors and software that enable autonomous or semi-autonomous operation, enabling precise movement and reducing human error. Through the integration of the Internet of Things (IoT), crane can provide data on real-time performance, usage patterns and maintenance needs, significantly reducing downtime.For example, smart crane are equipped with remote monitoring systems that allow operators to operate from a distance, ensuring safe operations in hazardous environments. Automatic features like anti-sway control also help maintain stability when lifting heavy loads, even in difficult environments. 2.Energy-saving design Sustainability has become an important concern and overhead crane are no exception. The application of energy-saving motors and regenerative braking technology enables the crane to recover energy during the braking process. The recovered energy can be used for other operations or fed back into the grid,…
