การป้องกันความปลอดภัยของเครนเหนือศีรษะแบบโลหการ

Due to its ability to significantly reduce the intensity of physical labor and improve labor productivity, metallurgical overhead crane has become an indispensable mechanical equipment in modern industry. Lifting machinery has the characteristics of large changes in mechanical load, diverse lifting forms, wide range of activity and operation, and complex working environment.

Characteristics of metallurgical cranes

(1) The widespread application of sensors and control technology

With the continuous updates of computer and sensor technology, it has also been widely used in metallurgical cranes. This improves the operability and automation level of metallurgical cranes. Programmed control enables metallurgical cranes to complete specific work tasks according to pre-set modes, while ensuring greater accuracy and timeliness. Remote control of cranes can also be achieved through telemetry and remote control technology. This can broaden its scope of work. Enable it to operate normally in harsh environments such as high dust, pollution, and high temperatures.

(2) The use of safety brakes

The lifting objects of metallurgical overhead crane are complex, including liquid metals, nuclear materials, large equipment, etc. During the lifting process, it is necessary to ensure the safety of personnel and equipment. So safety brakes should be installed in the main lifting mechanism of metallurgical cranes, which are mechanically controlled by hydraulic mechanisms. When starting a metallurgical crane, the safety brake works first. And the working brake on the high-speed shaft starts working again. When the metallurgical crane brakes, the working brake first applies the brake, and the safety brake delays the brake according to the pre-set time. In this way, the safety brake can ensure that the lifted object remains in a safe state when the transmission components in the transmission link are damaged or broken, without causing damage to equipment and personnel.
