<p>The invention concerns an electrically powered concrete pump for preparing and injecting concrete obtained by the technique of the inventive machine. The concrete pump mainly consists of a mixing drum (1) for mixing the materials, an electric motor (27) powering the assembly of mechanical elements and an air compressor and an assembly of accessories for optimising to a maximum the operating conditions and the performance. The mixing drum (1) is internally equipped with a replaceable curved wearing plate. The mixing drum (1) is equipped with a closure cover (46) resistant to the high pressure exerted by the air compressor during concrete transfer operations. On the mixing drum (1) are mounted two skips (34) or (hoppers) feeding the mixing drum (1) with building materials. It is shaped like a mobile visor and is synchronised with the movements of the machine.</p> |
