Installation and use of the protective devices for cranes

Cranes have become indispensable main lifting equipment in modern construction projects. But the accident also occurs from time to time, the cause of the accident is not only man-made, there is the cause of equipment failure. Therefore, in addition to doing a good job of equipment maintenance, but also to do a good job of safety protection devices. To make the Chinese lifting network crane in the operation of a better security, crane protection devices have many kinds, including wind and protective devices are in the port and open-air operation crane necessary equipment. Wind proof: Install an anemometer at an altitude of more than 50 meters at the top of the arm frame and emit it when the wind speed or operating limit wind speed exceeds the set point
