A hydraulic brake system for a passenger transport installation includes actuation equipment, a pump supplying brake fluid to a piston space of the actuation equipment and a motor driving the pump. A control device controls the motor by a frequency inverter whereby the pump supplies brake fluid at a predetermined delivery flow rate (QP). A pressure (pB) is set in the piston space corresponding to an equilibrium in which the delivery flow rate (QP) is equal to a return flow rate (QL). The control device sets the pressure (pB) by the delivery flow rate (QP) of the pump. The passenger transport installation can be a lift, an escalator or a moving walkway having this brake system operated according to the described method for controlling the braking force. |
