Crane cab air conditioning is widely used and critical, mainly for harsh working conditions such as high temperature, high humidity, dust, vibration, etc., to provide a comfortable environment for operators and ensure safe and efficient operation. The following are its typical application scenarios and specific solutions: port terminals (quay cranes, gantry cranes, etc.), metallurgical/casting workshops (casting cranes, metallurgical bridge cranes), open-pit mines (mining excavators, stackers and reclaimers), construction sites (tower cranes, truck cranes), container yards (RTG tire cranes, rail cranes), etc.
