FIELD: civil engineering, tower erection. SUBSTANCE: rail track (2) is laid on rubble base. Self- moving vehicle (3) may run through the rail track. Superstructure (4) of track and off-track vehicle (3) may be turned through 360 about trolley (5). Control cabin (6), contour weight (7), as well as lifting cantilever (8) are placed on the superstructure. Rotary/folding-back unit (9) is provided on free end of lifting cantilever (8). Guiding boom (11) with chuck (12) of pile driver is installed in guiding unit (10). Guiding boom (11) is vertical in operating position, and superstructure (4) is turned through 90 towards rail track direction. On completing the process of pile driving guiding boom (11) is secured by its middle using guiding unit (10) and turned using rotary/folding-up unit (9) through 90 . Guiding boom (11) with chuck (12) of the pile driver is folded using lifting cantilever (8). The device may move towards the next point of pile driving in this manner. EFFECT: high productivity. 1 dwg |
