The invention provides a roof crane, which solves the technical problems of complex and heavy steel structure, more structural parts and inconvenience in later-stage dismantling of tower crane parts which are lifted and dismantled by using a steel wire rope to pull a front arm to change amplitude and a winch in the existing roof crane, and can be widely applied to the field of hoisting cranes. The device specifically comprises a fixed base, a plurality of fixed supporting legs are fixedly connected to the fixed base, a rotating disc is further arranged on the fixed base, an inclined triangular frame is fixedly connected to the rotating disc, a rope winch is fixedly arranged on one bottom edge of the inclined triangular frame, and a telescopic top arm is hinged to the other bottom edge of the inclined triangular frame. A lifting arm is hinged to the top edge of the inclined triangular frame, and the vertex angle of the inclined triangular frame is arranged in the direction away from the lifting arm; the suspension arm comprises a four-frame suspension arm body close to the fixed base, one end of the four-frame suspension arm body is hinged to the top edge of the inclined triangular frame, and a jacking structure is arranged at the other end of the four-frame suspension arm body.

    本发明提供一种屋面起重机,其解决了现有的屋面吊用钢丝绳拉动前臂变幅,卷扬机起吊拆除的塔机零件,但其钢结构复杂笨重,结构零件多,后期拆除不便的技术问题,可广泛应用于起重吊领域;具体包括固定基座,所述固定基座上固定连接有多个固定支脚,所述固定基座上还设置有旋转盘,所述旋转盘上固定连接有斜三角架,所述斜三角架的一个底边上固定设置有绳索绞盘,另一个底边上铰接有伸缩顶臂,所述斜三角架的顶边上铰接有吊臂,所述斜三角架的顶角偏向远离所述吊臂的方向设置;所述吊臂包括靠近所述固定基座的四边框吊臂,所述四边框吊臂一端铰接在所述斜三角架的顶边上,另一端设置有顶起结构。
