20T Span 35m Double Girder Overhead Crane with Working Duty A6(ISO)
1.Brief introduction
The double-girder bridge crane is mainly composed of a bridge frame, a cart operating mechanism, a trolley, and electrical equipment. According to the frequency of use, it is divided into three working levels: A5, A6, and A7.
The operation of the hook bridge crane is all completed in the driver. An overload limiter, a large-screen display and various protection devices are added to further increase the safety during use. The double-girder overhead crane is generally operated in the air, which is different from other ground-operated cranes. Air operation is a separate small operation room under the crane, while ground operation is operated by the operator with a remote control.
