桁架结构在工程起重机中应用广泛,即通常所说的格构吊臂。它由四根主弦杆和若干腹杆组焊成3、6、9、12或15m一节的节臂,根据工作需要与杆头、杆尾实行多种组合,利于变换吊臂长度,同时利于拆装转运。由于使用、管理、转运等方面的原因,致使吊臂损伤、变形、甚至破坏,影响使用。现就我公司的实际情况谈谈体会。 Truss structures are widely used in construction cranes, which are commonly referred to as lattice booms. It is composed of four main chords and several web members welded into 3, 6, 9, 12 or 15m sections. According to the needs of the work, it can be combined with the club head and the end of the club to facilitate the change of the boom length. It facilitates disassembly and transportation. Due to the use, management, transportation, and other reasons, the arm is damaged, deformed, and even damaged, affecting its use. Let us talk about our company’s actual situation.
