Operating a crane in windy conditions can create a potentially dangerous situation. The wind forces imposed on both the crane and the load, which can affect the strength and stability of the crane. In order to ensure everyone’s safety during lifting operations, it is imperative that all members of the lifting team knowing the wind speed and the wind resistance.

The challenge of knowing the the wind speed is the connection between sensor and display. Traditional cable solution wouldn’t work well. Scarlet Wireless Anemometer Series provide elegant solutions ranges from simple display (WR-3), data logger (WL-11), data output model (W-110) full-fledged wireless alarming system (WL-410). The WL-11 Wind Speed Data Logger's wireless transmission ranges up to 250m or 1200m with the optional antenna. All data is stored within an SD card in data exchange format.
