Installation and application of protective devices for cranes

Anti-wind device: an anemoscope is mounted on the top of the boom at the height of more than 50m, which can raise the alarm when the wind speed or operating limit wind speed exceeds a set point, thus preventing accidents caused by sudden wind or incapability of distinguishing wind directions.

Protective device: for equipment with guardrails, guard plates, crawling ladders and so on, protective covers should be mounted on rotating parts of the machinery, to protect the completeness and reliability of parts; and guardrails must be mounted at the positions such as pedestrian paths and crawling ladders, to prevent personnel from falling off the machinery.
