Abstract

An apparatus, in particular suitable for the maintenance of pipelines, is described, said apparatus being designed to remove, by means of brushing, the external protective surface (consisting of a layer of bituminous material and/or polyethylene strips) of the pipes forming the pipeline. The brushing operation is performed by an operating unit which is arranged astride the pipe and which advances along the pipe itself with a discontinuous movement and receives the electric and/or hydraulic power necessary for operation thereof from a power unit which is physically separate from the operating unit and comprises at least one motor, at least one pump and/or at least one continuous current generator driven by said motor; the two units are connected together by means of connection means comprising at least one electric circuit and/or at least one hydraulic power circuit.
