Abstract

The invention relates to the technical field of engineering machinery, in particular to a lattice type variable diameter component boom and a crane. The lattice type variable diameter component boom comprises a lower arm, a variable diameter connecting piece, a horizontal connecting piece and an upper arm which are detachably connected from bottom to top in sequence. Width of the end, close to thelower arm, of the variable diameter connecting piece, is smaller than that of the end, away from the lower arm. The component boom can be combined into a boom with preset width efficiently and quickly.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a lattice variable-diameter component boom and a crane. Background technique [0002] The jib frame of crawler cranes is usually made of multiple joints with the same or different lengths connected by pins. By selecting the number and configuration of the joints, the length required for construction can be achieved. [0003] In order to effectively improve the anti-side load capacity of the boom, the area of ​​the boom section can be increased, especially the dimension in the width direction of the boom, so as to improve the stiffness of the boom against side loads, thereby improving the lifting capacity of the boom. However, existing techniques do not work well. Contents of the invention [0004] The purpose of the present invention includes, for example, to provide a lattice variable-diameter assembly jib and a crane, which can be efficiently and quickly combin...
