The utility model relates to the piling devices and may be used in the constructional engineering, especially in the densely populated areas, on small building grounds. The device for piling comprises two carriage beams (2) installed with the possibility of movement onto rails (1), equipped with displacement drives, with fixation of their position in the piling places and rigidly joined between them by cross main (3) and auxiliary (4) beams, placed with spacing between them, a vertical strut (5) with a piling mechanism, a movable bearing of the strut (5), installed onto said cross beams with the possibility of movement along them and equipped with a displacement drive, as well as counterweights (9) and (11). At the same time, the movable bearing of the strut (5) is made in the form of two longitudinal beams (8) placed under the cross beams (3) and (4), onto the anterior ends of which in front of the main beam it is fixed the vertical strut (5). The carriage beams (2) are made with stepping forth sectors, and the counterweights are constituted of three groups, of which one (9) is placed onto the carriage beams (2) between the main (3) and auxiliary (4) beams, and the other two (11) û in front of the strut (5) with spacing between them onto the stepping forth sectors of the carriage beams (2). Each of the longitudinal beams (8) is equipped with a U-shaped cramp (12) fixed onto its opposite to the strut end, formed by an upper horizontal flange and two vertical walls with formation between it and the upper surface of the longitudinal beam of a pathway, through which it is passed the cross auxiliary beam. |
