The invention provides a truss transition boom section, a crane boom and a crane. The truss transition boom section comprises a three-edged boom and connecting parts. The connecting parts are mounted at the vertexes of the three-edged boom, so that the three-edged boom is connected with a main body boom section or another three-edged boom. Through the structural arrangement, the three-edged boom can be spliced and connected with main body boom sections of different specifications through the connecting parts on the vertexes of the three-edged boom, so that a double-arm cargo boom and a single-arm cargo boom are formed. Compared with a transition boom section which is only suitable for a double-arm working condition in the prior art, the truss transition boom section has higher universality. Besides, the truss transition boom section can be connected with main body boom sections with different sizes, so that double-arm cargo booms with different arm distances can be formed, and different load-bearing requirements can be met.

    本发明实施例提供了一种桁架过渡臂节、起重臂架及起重机。其中,桁架过渡臂节包括:三棱臂架和连接件。所述三棱臂架的各个顶点处均安装有所述连接件,以使所述三棱臂架与主体臂节或者与另一三棱臂架彼此连接。通过这种结构设置,所述三棱臂架能够通过其各顶点上的所述连接件与不同规格的所述主体臂节拼装连接,以构成双臂起重臂架与单臂起重臂架。与现有技术中只适用于双臂工况的过渡臂节相比,该桁架过渡臂节具有较高的通用性。另外,该桁架过渡臂节能够与不同尺寸的主体臂节连接,可以构成具有不同双臂臂距的双臂起重臂架,以满足不同的承重需求。
