Brief Description
The heavy duty double girder bridge crane from YUNTIAN is mainly composed of box style bridge girder, hoisting trolley, traveling mechanism and electrical system. It is the optimal hoisting equipment for the operational sites where high speed and heavy duty lifting are required.
As the most commonly used hoisting machinery, this heavy duty crane is suitable for warehouse, freight yard and other sites. The attention, however, should be paid that our heavy duty double girder overhead crane is prohibited to be used in inflammable, explosive or corrosive environment.
This type of double girder bridge crane comes with super high lifting capacity that owes to its two hoisting hooks. That means it has two independent sets of lifting mechanism. The main hook is used to lift heavy objects while the auxiliary one is used to lift light objects.
In addition, the auxiliary hook can also be used to assist the main hook in tilting or tipping materials. However, when goods weight exceeds rated capacity, please do not use the two hooks to lift them at the same time.
YUNTIAN has become a major overhead crane manufacturer in China. Whether it is single girder overhead crane or double girder overhead crane, we assure you the highest quality and efficiency. If you need such type of double girder bridge crane, please contact us.
