The invention provides an engineering machine and a supporting system thereof, and the supporting system comprises a swinging part, the first end of the swinging part is hinged to the rear part of the engineering machine, the swinging part can swing around the first end in the horizontal direction, and the swinging part is provided with a swinging position and a retracting position relative to the engineering machine; and the supporting part is arranged at the second end of the swinging part, and the supporting part can move in the vertical direction. When supporting is needed, the swing part swings to the swing position relative to the engineering machine, and the supporting part descends to make contact with the ground and conducts supporting. When supporting is not needed, the supporting part ascends, and the swing part swings to the retracting position relative to the engineering machine. Compared with a fixed type supporting system, the swing type supporting system can swing and retract when supporting is not carried out, and therefore the length of the whole machine is not increased; compared with a telescopic type, the swing part is hinged to the rear portion of the engineering machine, structures such as a cavity and a supporting leg cavity do not need to be arranged on the rear portion of the engineering machine, and therefore the structure is simple and assembling is easy.

    本发明提供了一种工程机械及其支撑系统,其中,支撑系统包括:摆动部,摆动部的第一端铰接在工程机械的后部,摆动部能够绕第一端在水平方向摆动,并且摆动部相对于工程机械具有摆开位置和收回位置;支撑部,设置在摆动部的第二端,并且支撑部沿竖直方向可移动。需要进行支撑时,摆动部相对于工程机械摆动至摆开位置,支撑部下降至与地面接触并进行支撑。不需要进行支撑时,支撑部上升,并且摆动部相对于工程机械摆动至收回位置。上述摆动式的支撑系统相较于固定式相比,不进行支撑时可以摆动收回,因此不增加整机长度;相较于伸缩式相比,摆动部铰接在工程机械后部即可,不必在工程机械的后部设置腔体、支腿腔等结构,因此结构简单且易于装配。
