Abstract: IN THIS LIFT INSTALLATION, LIFT BRAKING EQUIPMENT (11) BRAKES AND HOLDS A LIFT CAGE (2). THE LIFT BRAKING EQUIPMENT (11) CONSISTS OF A NUMBER OF BRAKE UNITS (12) WHICH WHEN REQUIRED ARE BROUGHT INTO ENGAGEMENT WITH BRAKE TRACKS (6), WHEREIN THE BRAKE UNIT (12) FOR THIS PURPOSE PRESSES AT LEAST ONE BRAKE PLATE (14) AGAINST THE BRAKE TRACK (6) AND PRODUCES A BRAKING FORCE (FB). ACCORDING TO THE INVENTION, FOR CHECKING THE BRAKING EQUIPMENT (11) AN EFFECTIVE COEFFICIENT OF FRICTION (?E), WHICH IS GENERATED DURING PRESSING OF THE BRAKE PLATE (14) AGAINST THE BRAKE TRACK (6), OF THE BRAKE UNIT IS ASCERTAINED. MOREOVER, A PLACING IN OPERATION WITH USE OF THIS CHECKING METHOD IS ILLUSTRATED AND EQUIPMENT FOR PERFORMING THIS PLACING IN OPERATION IS PRESENTED. (FIG. 4)

Abstract: In this lift installation, lift braking equipment (11) brakes and holds a li ft cage (2). The lift braking equipment (13) consists of a number of brake units (12) which when required are brought into engagement with brake tracks (6), wherein the brake unit (12) f or this purpose presses at least one brake plate (14) against the brake track (6) and produc es a braking force (FB). According to the invention, for checking the braking equipment (11) an effective coefficient of friction ( e), which is generated during pressing o f the brake plate (14) against the brake track (6), of the brake unit is ascertained. Moreover , a placing in operation with use of this checking method is illustrated and equipment for performing this placing in operation is presented.

Abstract: The subject of the invention is a lift installation (1) with a lift cage (2) , which moves in vertical direction along guide tracks (7). In the case of need the lift cage (2) is braked by a braking equipment (11) or held at standstill. The braking equipment (11) consists of at least two brake units (12). According to the invention at least one of the brake units (12), but preferably each of the brake units (12), is provided with a wear- compensating device (30) which, when the brake unit (12) is relieved, sets a clearance (If), i.e . a free distance between brake lining (15) and associated brake surface, which arises on opening of a brake, in correspondence with a substantially constant value. It is thereby achieved that use may be made of customary and thus economic brake materials which may wea r during braking. (Fig. 2)

Abstract: An elevator installation has braking equipment for braking and holding an elevator car which moves in vertical direction within guide tracks or rails. The braking equipment consists of at least two brake units each comprising a normal force regulation device that sets a normal force (FN) in correspondence with a normal force value determined by a brake control unit and/or a locking device that locks the brake unit in a set braking position and which preferably maintains the set braking position in the case of an interrupted energy supply. The braking equipment provides a gentle braking or holding of the elevator car, which corresponds with the operational state of the elevator installation, with a low energy requirement.

Abstract: An uninterruptible power supply wherein an isolation device is automatically tested during normal operation to ensure that it is capable of effectively isolating the input from an auxiliary power supply during emergency operation. The uninterruptible power supply includes an input for coupling to a main power supply, an output for connection to an electrical load, an auxiliary power supply and a selective isolation device configured to isolate the auxiliary power supply from the input during emergency operation. First components establish a reverse polarity across the isolation device for a test period during normal operation, and second components monitor a voltage proportional to the input voltage to the isolation device and output an error signal if the monitored voltage remains or rises above a first reference value during the test period.

Abstract: The invention relates to a safety brake 9 for an elevator, comprising a brake element 6 or a brake wedge 63, a guide element 2 and a control device 20. The brake element 6 or brake wedge 63 are slidably mounted on the guide element 2. The safety brake 9 has an additional actuating element 11, which when the safety brake 9 is actuated can be made to operatively engage the brake element 6 or the brake wedge 63. The guide element is embodied in such a manner that during the braking operation, the movable guide element can be moved back into its original rest position.

Abstract: In this lift installation a lift cage (2) is arranged to be movable along guide rails (6) and the lift cage (2) is equipped with a brake system preferably with two safety brakes (20) The safety device is activated by way of control devices (10, 11) which can trigger the safety device from critical or non-critical events. The control devices further include a function for automatic resetting (A) of the safety brake (20) when an event, which is evaluated as non-critical, is indicated as a reason for triggering the safety brake. Resetting of the safety brake (20) takes place through execution of pre-defined resetting steps (R) of the lift cage (2). (see figure 3)
