The invention relates to the technical field of engineering machinery, and provides an on-load displacement device and an operation machine.The on-load displacement device comprises a first swing frame and a second swing frame, the first end of the first swing frame is rotationally connected to a rotary table, the rotating axis is arranged in the vertical direction, and the first end of the second swing frame is rotationally connected with the second end of the first swing frame; the second end of the second swing frame is a free end. According to the arrangement, after the counterweight assembly is detached from the first swing frame and the second swing frame, the second swing frame is rotated to the lower part or one side of the first swing frame, so that the longitudinal length of the on-load displacement device along the crane can be reduced, and therefore, when the on-load displacement device runs along with the crane, the longitudinal length of the whole crane is reduced, and the trafficability of the crane is ensured; the problem that an on-load displacement device in the prior art is inconvenient to run along with a vehicle is solved.
本发明涉及工程机械技术领域,提供一种带载变位装置及作业机械,其中,带载变位装置包括第一摆动架和第二摆动架,第一摆动架的第一端转动连接于转台,转动轴线沿竖直方向设置,第二摆动架的第一端与第一摆动架的第二端转动连接,第二摆动架的第二端为自由端。如此设置,将配重组件从第一摆动架和第二摆动架上拆下后,使第二摆动架转动至第一摆动架的下方或一侧,可以减小带载变位装置沿起重机纵向的长度,从而在带载变位装置随车行驶时,减小起重机整车的纵向长度,保证起重机的通过性,解决了现有技术中的带载变位装置不便于随车行驶的问题。
