Abstract

A high safety hydraulic device for the operation of sectional overhead doors (POR), of the type comprising at least one hydraulic cylinder (CI), connected to at least one hydraulic circuit (MI), which allows the opening or closing of the overhead door (POR), through an electro-hydraulic motor (M), suitable for operating at least one pump for the circulation of a fluid within at least one pipe (TU) of the hydraulic circuit (MI); in particular, between the hydraulic cylinder (CI) and the discharge tank (SC) placed downstream the motor (M), is provided at least one first solenoid valve (VA), normally closed, placed at the outlet of the hydraulic cylinder (CI) and preferably integral with it, and a second solenoid valve (NS), normally closed, placed between the pipe (TU) and the discharge tank (SC).
