Abstract
The invention relates to a process for releasing at least one spring accumulator brake (), which is operated by a pressure medium and which is connected to a brake-release-pressure-supply-circuit () in normal operation for impact with a brake release pressure and which, in service operation, is detached from the circuit () in case of failure of the brake release pressure and is released through a pressure medium source () against the spring force of the spring accumulator. To develop the process in such a way that the risk of an accident taking place reduces after the brake release pressure has failed, it has been proposed in the invention that at least one brake () gets re-connected automatically with the circuit () when the brake release pressure is provided again. Further, an apparatus and a hydraulic circuit for carrying out the process are proposed.
