FIELD: machine building.SUBSTANCE: invention relates to manipulator cranes. Z-shaped buildable crane comprises crane mast (9), lifting arm (3), which is hinged at one end to crane mast (9), and at the other end is provided with a fork-shaped receiving portion for articulated arm (1), articulated arm (1), while articulated arm (1) is formed as a shaped pipe and has a first end and a second end, hinge joint (8) that connects articulated arm (1) and lifting arm (3), while hinge joint (8) is located in the area of the second end of articulated arm (1), telescopic arm (2), which is mounted in articulated arm (1) and can, from the retracted position in articulated arm (1), extend out from the first end of articulated arm (1). Hinge joint (8) is located outside the shaped pipe of articulated arm (1), so that telescopic arm (2) can extend past hinge joint (8), and telescopic arm (2), in the retracted position in the direction indicating from the first end of articulated arm (2), extends beyond hinge joint (8) with lifting arm (3).EFFECT: increase in the range of the crane is achieved.11 cl, 8 dwg
