European single-girder crane has light weight, compact structure and low energy consumption. European-style crane adopts a unique design concept, which has the characteristics of small size, light weight and small wheel pressure. Compared with traditional cranes, the distance between the hook and the wall The limit distance is small, the headroom is low, Keli crane can work closer to the front, and the lifting height is higher, which actually increases the effective working space of the existing factory building. Because the crane has the characteristics of light weight and small wheel pressure, the space of the new factory building can be The design is smaller and the functions are more complete. Smaller workshops mean initial construction investment, as well as long-term heating, air conditioning and other maintenance costs can save a considerable sum of money.
