Improvements in hydraulic presses, essentially characterized by providing the presses with a solid bridge with lateral openings accessible from the outside, inside which is arranged a set of adjustable coil springs, which at their lower end are mounted on a crosspiece fixed on the actuator piston of the mobile table of the press, by means of which set of springs is pressed downwards to said table in the disengagement or drainage phase, by effect of the distension of the springs, which are compressed at the moment of pressing.
