Characteristics and application of QD type double girder overhead crane
QD type electric double-girder crane is a common lifting equipment. Its main features are that the trolley conducts electricity and adopts a new I-shaped steel track cable conduction device, which is safe and reliable. The bridge frame of QD hook bridge crane adopts box-shaped main girder and is welded by automatic submerged arc welding. It is worth mentioning that the lifting mechanism can also change according to requirements, for example, a second set of safety devices can be installed. This increases the safety of the device during use. Parts meet the requirements of standardization, serialization and generalization. When the operator is operating, he has a wide field of vision, all of which are operated indoors, and the work is flexible and the working environment is comfortable.

QD hook bridge crane is widely used, such as loading, unloading and handling of ordinary heavy objects, and it can also be equipped with a variety of special cranes for special operations. The advantage is that it is equipped with rainproof equipment when used in the open air. The data in the table is for indoor cranes. The total weight and wheel pressure of outdoor cranes will increase by about 5%. When selecting, the technical requirements such as the working system, the higher and lower temperature of the working environment and the type of power supply should be indicated. It can also be designed and manufactured according to the span required by users.
