Abstract

The embodiment of the invention provides a truss assembly and a cargo boom, and relates to the field of cargo booms. A problem that the cargo boom with a larger width is assembled by a single component with a larger size and weight and is difficult to install is solved. The truss assembly comprises two reducing joints, a third arm frame and side arm frames, wherein the two reducing joints are arranged at intervals; the number of the side arm frames is two, and the two side arm frames are symmetrically arranged on two sides of the third arm frame; and two ends of the third arm frame and the twoside arm frames are connected with a first arm frame and a second arm frame through the reducing joints. The third arm frame is a conventional arm frame configured by a crawler crane in a standard state, and on the basis of the third arm frame, a user only needs to additionally purchase the reducing joints and the side arm frames to increase a section width of the arm frame, and a loading capacity of the cargo boom can be upgraded without additionally purchasing a whole set of arm frame with the larger width, and cost for upgrading an arm frame capacity of a client is reduced.

Description

technical field [0001] The invention relates to the field of booms, in particular to a truss assembly and a boom. Background technique [0002] The jibs of existing lattice jib cranes are usually connected by multi-section jibs in a hinged manner. In the lattice jib crane, components such as connecting parts, jib frame and jib head parts can be transported to the hoisting site, and the connecting parts, jib frame and jib head parts can be assembled by hinges. In the working state of the lattice boom crane, the boom can be mounted on the crane turntable by being hinged along the horizontal axis, so that it can be lifted or lowered in the vertical plane. [0003] When the lattice jib of a crane lifts a large load, the limit to the lifting capacity is usually not the ability of the jib to resist the deflection in the vertical lifting plane, but the lateral deformation in the horizontal plane, that is, the ability to resist lateral loads . Assembling a wider jib from individu...
