Abstract (en)
[origin: DE4439930A1] A concrete pumping device has a bearing arm that is cantilevered in its working position and that positions the end (11) of a pumping line (5). The bearing arm (8) has segments (6) that bear each at least one of the pipe segments (4) that compose the pumping line (5). In order to increase the achievable pumping height, at least one of the bearing arm segments (12) may be telescopically extended and can move from a nested initial position into at least one extended position in which the extensible bearing arm segment (12) is longer than the associated pipe segment. At least one device (17) for supplying at least one additional pipe segment (16) can be moved from a first position in which the additional pipe segment (16) is located away from the volume occupied by the pipe segments (4) into a second position in which at least one end section (20) of the additional pipe segment (16) is aligned with at least one end section (21) of a pipe segment (4). The pumping line (15) is essentially made up of the pipe segments (4) and the additional pipe segment (16).
