Abstract
1. Braking device for pressure medium cylinders, especially cylinders (26) without a piston rod, having a braking element (9, 9') which can be operated on by pressure medium, this pressure medium operation being monitored by a switch valve (8, 8'), characterised in that between a pressure medium source (1) and the switch valve (8, 8'), constructed at least as a 3/2-way valve, there is arranged a pressure medium reservoir (4) which can be charged by means of a non-return valve (3) from the pressure medium source, in that the pressure of the pressure medium source (1) acts on a pressure monitor (5) which, when a first high pressure threshold is not reached, switches the switch valve (8, 8') so that it opens an otherwise closed connection from the pressure medium reservoir (4) to the brake element (9, 9'), in that a spring-loaded cylinder (13), acted on by the pressure medium reservoir (4), is provided which, when acted on by a pressure which falls below a second mean pressure threshold, activates a mechanical movement lock (14, 16) arranged in parallel to the braking element (9, 9'), and in that the braking element (9, 9') is designed to maintain the nominal load of the pressure medium cylinder until its actuation pressure falls below a third, low pressure threshold.
