Cranes

State-of-the-art technologies for innovative solutions.

Since mobile cranes are often deployed in urban areas where stringent noise emission regulations apply, a strong focus is placed on the noise emissions of the fan. WingFan’s state-of-the-art BLEX blade extension technology has been successfully implemented in mobile crane applications to reduce the fan noise emissions by 2 dB(A). Our high performance S38 blade profile reduces noise emissions by achieving the same airflow as competitor’s fans but with an rpm reduction of up to 300 rpm.
