The embodiment of the invention provides a boom system and an engineering vehicle. The arm support system comprises an arm support main body and a telescopic piece, the boom main body comprises a basic boom and a telescopic boom; the telescopic piece comprises a first component connected with the basic arm and a second component connected with the telescopic arm, and the second component stretches out and draws back relative to the first component in the axial direction of the second component so as to drive the telescopic arm to stretch out and draw back relative to the basic arm; the first component is further provided with a first swing center, and the first component can swing in the rotation plane relative to the first swing center and can drive the second component to swing in the rotation plane relative to the first swing center. According to the boom system, the possibility that the telescopic part bears radial loads can be reduced, the sealing performance of the telescopic part is better, and therefore the service life of the telescopic part is prolonged, and the reliability of the boom system is improved.
