The invention relates to the technical field of steel cross beam lifting, in particular to a special lifting tool for lifting an I-shaped steel cross beam. The special lifting tool comprises a triangular plate, two symmetrically distributed L-shaped plates are arranged at the lower end of the triangular plate, a metal chain is connected between the triangular plate and each L-shaped plate, a crossrod penetrates through the triangular plate, and multiple uniformly distributed triangular plates are fixedly connected to the cross rod. A square hole is formed in each L-shaped plate, and a clamping plate is arranged in the square hole of each L-shaped plate. According to the special lifting tool for lifting the I-shaped steel cross beam, the multiple L-shaped plates can be quickly hooked on the I-shaped steel, the L-shaped plates can be hooked on the I-shaped steel only by manually pulling a pull ring, and therefore the multiple L-shaped plates can preliminarily hook the I-shaped steel, then lifting is conducted, the multiple clamping plates naturally rotate and are turned out, and the clamping plates and the L-shaped plates are matched to clamp the I-shaped steel. The function is stable and powerful, and the steel part transportation efficiency is improved.
本发明涉及钢横梁吊装技术领域,具体为一种工字钢横梁吊装专用吊具,包括三角板,三角板的下端设置有两个对称分布的L型板,三角板和L型板之间连接有金属链,三角板上贯穿有横杆,横杆上固定连接有若干均匀分布的三角板,L型板上开设有方形孔,L型板的方形孔中设置有夹板,本发明实现若干L型板快速钩在工字钢上,只需要手动拉扯拉环,即可将L型板钩在工字钢上,如此实现若干L型板初步挂住工字钢,随后起吊,若干夹板自然转动翻出,夹板和L型板配合夹住工字钢,功能稳定强大,提高钢件的运输效率。
