Port machinery

The working characteristics of hoisting and transportation machinery are intermittent movement. Each machinery is often in the working state of startup, braking and forward and reverse operation. Although its operating speed is not high, it often carries heavy loads, and it has been working continuously in harsh environments such as dust or sea water humid corrosion for a long time. The equipment must be efficient, continuous, stable, reliable, easy to maintain and long life. Low speed, heavy load Requirements for high reliability and long service life. At present, bearings are mainly used in gearbox, traveling mechanism, hoisting mechanism, luffing mechanism, slewing mechanism, etc.
