The determination of a crane’s lifting capacity primarily hinges on several engineering and operational factors, among which weather conditions can play a significant role. Adverse weather, such as high winds or rain, can compromise the stability of the crane and its ability to safely lift and maneuver loads. For example, strong winds can sway the crane's boom and affect its balance, increasing the risk of tipping or losing control of the load. Operators must consider these conditions when assessing how much weight the crane can handle at any given time.

While the experience level of the operator and the size of the crane are indeed important factors, they are not as directly related to the crane's inherent lifting capacity as weather conditions are. An experienced operator might still face severe limitations on a stormy day, just as a larger crane may have its capacity restricted under certain weather conditions despite generally being able to lift heavier loads. The color of the crane has no relevance to its lifting capacity whatsoever, making it an irrelevant factor in this context.
