Abstract

Improvements introduced in the object of main patent no. 430136, filed on September 17, 1974, for: IMPROVEMENTS IN PUMPING DEVICES FOR PUMPING FLUID MATERIALS, of the type of apparatus that includes a hopper to receive a plastic mass, for example concrete, with side walls and a bottom wall; a discharge line extending from the hopper; and a pumping cylinder having one end in communication with the hopper; whose hopper has bearing boxes supported by its opposite walls, whose boxes with riders have bearings supported in them and that define axially aligned openings and because the conduction tube has an extension at the open end, whose extension is rotatably supported in an opening defined by one of the bearing boxes, characterized in that the hopper is provided with a support fixed to it, the discharge line being fixed to the support, axially aligning with said extension.
