<p>There is a saddle trailer with a concreting pump assembly on it, incorporating a rotatable and extensible concreting nozzle with rotary head and filler funnel. The trailer has a neck piece which is in front, in the direction of travel, while the rotary head (1) on the extensible nozzle (2) is mounted in the rear area. The filler funnel (3) is pref. in the forward area. The neck piece may easily swivellable, pref. upwards, or may be in two or more pieces both able to swivel to the side. The neck piece may also be readily detachable, and easily coupled onto the trailer. This layout makes it possible to bring the rotary head appreciably closer to the desired point on the building.</p> |
