Wind Conditions and Crane Safety : Anenometer for Tower Crane (Digital Wireless Weather Station) With Dual-Mount Wind Sensor. 
 
Operating tower cranes and any other heavy lifting equipment like crawler cranes bring clear financial and personal responsibility.

Cranes are exposed to a vast amount of hazards that make them prone to accidents and wind speed is a critical risk factor for cranes and lifting equipment, even when they are idle.
 
Between 2000 and 2010 there were 1,125 accidents and 780 fatalities worldwide in tower crane accidents(1):
 
23% of these accidents were caused by high winds Forecasting is essential when working at height, and a safety requirement for operating cranes and heavy lifting equipment. Major contractors, crane manufacturers, the CPA Tower Crane Interest Group and the INDIA Heath and Safety Executive conclude that -  The maximum recommended wind speed for tower cranes in the India should be:
38mph (16.5m/s or 60kph) and
completely prohibited over 45mph (20m/s or 72kph)
 
Ultimately the crane may be taken out of operation at lower wind speeds due to the type of load being lifted or difficulty in controlling it under wind pressure. The crane operator has the primary responsibility in conjunction with the crane supervisor to make that decision.
