    摘要: A telescopic extraction arm, comprising a first telescopic tube (2) defined by two telescopic sleeves (6,7) slidingly coupled one to another, a second tube (10) connected to a lower end of the lower sleeve (7) of the first tube (2) by means of a first joint (11), which is configured at least to enable rotation of the second tube (10) relative to the first tube (2), a suction nozzle (12) connected, by means of a second joint (13), at one end (10b) of the second tube (10), which end (10b) is opposite to the first tube (2), the second joint (13) being configured at least to enable rotation of the suction nozzle (12) relative to the second tube (10), a counterweight (15), slidingly mounted on the upper sleeve (6) of the first tube (2) in order to compensate the weight of the sliding part (7, 10, 12) of the arm (1), during the raising step, and a plurality of wires (17) connecting the counterweight (15) with the lower sleeve (7) of the first arm (2), as to effect a raising of the counterweight when the lower sleeve (7) of the first tube (2) is lowered and vice versa.
