Climbing frame electric hoist is a kind of light and small lifting equipment often used in hoisting machinery. Due to its simple structure, high operating efficiency, it is widely used in the construction industry. Although the climbing frame hoist is a light and small lifting device, it can now reach 100 tons. Although the climbing frame electric hoist is convenient, the occurrence of faults not only affects the working efficiency, but also has a great job safety hazard, so it is necessary to detect the problems of the climbing frame electric hoist. As the equipment age increases, there are many reasons for the accident of the electric hoist, but 80% of the parts are inside the electric hoist, and the external inspection alone cannot effectively detect the operating conditions of the internal components of the electric hoist during the annual inspection, and it cannot be detected. The hidden faults of the electric hoist of the climbing frame make it impossible to effectively detect its running status; this also makes the annual inspection lose its original meaning, and it also plantes bad seeds for the future use of product safety, so it is necessary to talk about the internal situation of the equipment How to evaluate and test, first of all, the operation status and fault diagnosis skills of the equipment have been more mature after more than 30 years of research and development, and have entered the practical stage. It has played a very critical role in ensuring the safety of equipment and high quality economy. effect.
