FIELD: physics.
SUBSTANCE: crane comprises a base 1, an upright pillar 2 mounted on the base 1 adapted to be rotated about the vertical axis by the first actuator 3, an arrow, which is made of the front part 4 and the beam-counterweight 5, wherein the front part 4, the beam-counterweight 5 and the pillar 2 are connected by the first hinges 6, an intermediate hinge element 7 mounted on the end 8 of the front part 4, a hanger 9 for fixing a film- or teleshooting equipment 10 mounted on the intermediate hinge link 7, and a mechanism for adjusting the relative angular position of the front part 4 and the beam-counterweight 5. The front part 4 and the pillar 2 are adapted to be rotated by the second actuator 11 at the relative angular. The intermediate hinge link 7 is connected with the pillar 2 by the rod 12, which is connected with the intermediate hinge link 7 and the pillar 13 by the second hinges 2, wherein the rod 12 is connected with one of the hinges 13 via the first elastic-damping device 14. The intermediate hinge link 7 is connected to the front part 4 by the third hinge 15. The hanger 9 is connected with the intermediate hinge link 7 by the fourth hinge 16. The front part 4 is made with a rigid arm 21, the free end 22 of which and the beam-counterweight 5 are connected with the device 24 by the sixth hinges 23, damping the relative angular displacement of the front part 4 and the beam-counterweight 5.
EFFECT: reducing the vibrations in the vertical planes of the hanger for mounting the film- or teleshooting equipment, the intermediate hinge link, the front boom part and the beam-counterweight.
