Vibrodispensing machine intended to dispense concrete into the moulds of a prefabrication bench and to vibrate the concrete

摘要

A machine according to the invention comprises a self-propelled trolley 5 which moves on a lengthwise track and straddles the prefabrication bench. This trolley carries a tub for concrete 8. It carries a transverse beam 12 placed at the rear of the tub, which supports vibrating cases 14 under which pairs of vibrating needles 17a, 17b are suspended, which follow a mould. The trolley carries a second transverse beam 22 which supports articulated arms 24 carrying at their ends a bucket 26 which recovers the excess concrete. One application is the manufacture of beams, girders or posts made of prestressed concrete. <IMAGE>
