The LD type electric single beam crane has the characteristics of reasonable structure and strong rigidity of the whole machine. The whole machine is used with CD1, MD1 and HC electric hoists. It is a light and small lifting machine. Its lifting capacity is 1t-32t. The span is 7.5-22.5m, the working level is A3-A5, and the working environment temperature is -25-40°C.
This product is widely used for lifting goods in factories, warehouses, stockyards and other occasions. It is forbidden to use in flammable and explosive corrosive media environment.
This product has two operating modes: ground and control room. There are two types of control room: open type and closed type. It can be divided into left or right side according to the actual situation. There are two types of side and end faces in the direction of the door to meet the user's choice in various situations.
