Rotating central column with hydraulic horizontal movement, arranged in an assembly for changing hoppers and tanks for lorries

摘要

The invention relates to a rotating central column made of structural steel, with a hydraulic horizontal movement, arranged in an assembly for changing hoppers and tanks for lorries, with access to two adjacent working areas and provided with an inner hydraulic oil tank. Said column also comprises an inner carriage coupled to an arm forming a carriage-arm assembly moving vertically by means of the action of a hydraulic cylinder, and also has angular mobility of 90°. The rotating central column rotates on its vertical axis by means of the 180° rotation of the turntable on which it is mounted, said turntable being formed by a ring gear-pinion assembly actuated by a hydraulic engine and forming part of the base of the rotating central column.
