Rated lifting capacities do not account for wind on lifted load or boom. We recommend against working under the conditions that the load is out of control due to a strong wind. 

Truck Crane: During boom lift, consider that the rated lifting capacity is reduced by 60% when the instantaneous wind speed is 9m/s to 12m/s; reduced by 80% when the instantaneous wind speed is 12m/s to 14m/s. if the instantaneous wind speed is 14m/s or over, stop operation. During jib lift, stop operate if the instantaneous wind speed is 9 m/s or over. It applies to all the truck crane of SANY under 100t(Not include 100t)

Rough terrain crane: During boom lift, consider that the rated lifting capacity is reduced by 60% when the instantaneous wind speed is 9m/s to 12m/s; reduced by 80% when the instantaneous wind speed is 12m/s to 14m/s. if the instantaneous wind speed is 14m/s or over, stop operation. During jib lift, stop operate if the instantaneous wind speed is 9 m/s or over. It applies to all the truck crane of SANY under 100t(Not include 100t), It applies to all the rough terrain crane of SANY

All terrain crane: 

During boom lift, When the boom length is 36m below( include 36m), consider that the rated lifting capacity is reduced by 50% when the instantaneous wind speed is 11.4m/s to 14m/s; if the instantaneous wind speed is 14m/s or over, stop operation. 

During boom lift, When the boom length is over 36m, consider that the rated lifting capacity is reduced by 50% when the instantaneous wind speed is 9-11.1m/s; if the instantaneous wind speed is 11.1m/s or over, stop operation.
