A crane landing leg and hoisting equipment belong to the technical field of hoisting equipment, the crane landing leg comprises a landing leg main body, the landing leg main body comprises a first leg part and a second leg part which are fixedly connected, the first leg part is located above the second leg part, the cross section of the first leg part is elliptical, and the cross section of the second leg part is circular. The first leg part of the upper part of the supporting leg main body is of a structure with an oval cross section and is provided with a long shaft and a short shaft, and the long shaft and the short shaft have different torsional rigidities, so that stress can be more effectively distributed when the upper part of the supporting leg main body bears torsional moment, and better torsional performance is provided; the second leg part of the lower part of the supporting leg main body is of a structure with a circular cross section, and a variable cross section arrangement mode is adopted, so that the torsion resistance and the supporting stability are improved, the use of materials is reduced, the use cost is reduced, the overall mass is reduced, and the energy consumption is reduced.
一种起重机支腿及起重设备,属于起重设备技术领域,包括支腿主体,支腿主体包括固定连接的第一腿部和第二腿部,第一腿部位于第二腿部上方,第一腿部的横截面呈椭圆形,第二腿部的横截面呈圆形,支腿主体上部分的第一腿部为横截面呈椭圆形的结构,具有长轴和短轴,其长轴和短轴具有不同的抗扭刚度,这种特性使得支腿主体的上部分在承受扭转力矩时能够更有效地分布应力,从而提供更好的抗扭性能,支腿主体下部分的第二腿部为横截面呈圆形的结构,采用变截面的设置方式,在提高抗扭性能、支撑稳定性的同时,还减少了材料的使用,降低了使用成本,且还降低了整体质量,减少了能耗。
