The invention discloses a novel crane with a foldable rotary table. According to the novel rotary table foldable crane, the overall height of the crane is reduced (the requirement for low-space passing after loading is met), the turning radius of the crane is reduced, the pitching angle range of a crane boom is increased through multiple joints, and the minimum operation amplitude limit is broken through. Comprising a connecting plate, an arm support, a rotary table luffing cylinder, an arm support luffing cylinder and a telescopic arm, the bottom of the arm frame is hinged to one side of the connecting plate, and the top of the arm frame is hinged to the tail of the telescopic arm; one end of the rotary table luffing cylinder is hinged to the other side of the connecting plate, and the other end of the rotary table luffing cylinder is hinged to the position, close to the middle, of the rear side of the boom; and one end of the boom amplitude variation cylinder is hinged with the front side of the boom close to the bottom position, and the other end of the boom amplitude variation cylinder is hinged with the lower part of the telescopic boom close to the tail position. The invention has the characteristics of reducing the overall height of the crane, reducing the turning radius of the crane, increasing the pitching angle range of the crane boom by multiple joints, breaking through the minimum operation amplitude limit and the like.
