SUPPORT STRUCTURE CAPABLE OF IMPROVING JIB BEARING CAPABILITY AND CRANE WITH THE SUPPORT STRUCTURE

摘要

Disclosed is a structure capable of improving a jib bearing capability and a crane with the structure. The crane with the support structure comprises a jib, a jib head, a pulling plate, a lifting hook pulley block and a support structure. The jib head is fixedly installed on an upper end of the jib. The lifting hook pulley block is fixedly connected to the jib head. An upper end of the support structure is connected to the pulling plate. A lower end of the support structure is matched with the jib head and is fixedly connected to the jib head. By means of the structure capable of improving a jib bearing capability and a crane with the structure of the present invention, through addition of the support structure on a bearing system of an original crane jib, the bending moment of the lifted weight relative to the jib head can be effectively eliminated or reduced, and thus all jib components bear uniform loads and a jib bearing capability is greatly improved so that a crane lifting capability is further improved.
