ES284348U - Perfect mechanism for hydraulic or similar lifting tables (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved mechanism for hydraulic lifting tables or the like, which consist of a hydraulic assembly with own lifting/lowering means and where the piston is preferably fixed to the lifting table of the table and the sleeve is integral, preferably, to its structure. Support and is characterized because: A) - the aforementioned lifting means consist of: A1) - two storage and pushing chambers respectively interconnected by a circuit provided with: A2) - a set of at least three unidirectional intake, thrust and discharge valves, of which two (intake and thrust) are operated with the operation of: A3) - a thrust pump that, for the ascent, transfers fluid from said storage chamber to said thrust chamber, through said unidirectional intake and thrust valves, A4) - a discharge handle actuated - manually or automatically - to, in the descent, allow the passage of fluid from the thrust chamber back to the storage chamber, through said discharge valve; B) - the piston attacks directly on the lifting frame, being secured by means of a pin to a baga, which in turn is fixed to the lifting shaft bushing, preferably by welding; C) - the lifting chamber conforms its trunk-conical base, so that the base of the piston, exclusively against its larger perimeter, meets in an extreme position.
