Boom device and working vehicle
The invention relates to the technical field of engineering machinery, in particular to a cantilever crane device and an operation vehicle, the cantilever crane device comprises a first cantilever crane and a second cantilever crane, one end of the first cantilever crane is hinged to one end of the second cantilever crane, and the first cantilever crane and the second cantilever crane are stacked up and down in a folded state of the cantilever crane device; a bent arm section is arranged at the end, hinged to the second arm frame, of the first arm frame, and the bent arm section is bent in the direction away from the second arm frame. By means of the structure, the section of a box body at the end, hinged to the second arm frame, of the first arm frame can be heightened, so that rigidity and torsion resistance of the first arm frame are improved, meanwhile, due to the fact that the bent arm section of the first arm frame is bent in the direction away from the second arm frame, a space is reserved for the end, hinged to the first arm frame, of the second arm frame, the section of the box body of the second arm frame can be heightened, and rigidity and torsion resistance of the second arm frame are improved. And therefore, the rigidity and the torsion resistance of the second arm support are obviously improved.
本发明涉及工程机械技术领域，具体涉及一种臂架装置及作业车辆，臂架装置包括第一臂架、第二臂架，第一臂架的一端与第二臂架的一端铰接，在臂架装置的折叠状态，第一臂架与第二臂架上下层叠设置，第一臂架上与第二臂架铰接的一端设有弯折臂段，弯折臂段向远离第二臂架的方向弯折。能够使第一臂架在与第二臂架铰接的一端的箱体截面做高，从而提升第一臂架的刚性和抗扭性，同时由于第一臂架的弯折臂段向远离第二臂架的方向弯折，也给第二臂架与第一臂架铰接的一端留有空间，可使第二臂架箱体截面做高，进而使得第二臂架的刚性和抗扭性得到明显提升。
