The minimum holding capacity (braking force) for dryrunning or mineral-oil wetted shafts is at least 2 x M but does not exceed 3,5 x M. 2 p is the pressure required for releasing. The permissible working pressure is 10 bar. 3 Regarding safety it is an advantageous feature of the Safety Brake KSP , that it normally will not release unless not only pressure is applied but also the load is supported by the lifting drive, thus automatically unintended releasing is prevented. However, this is only true, if the load exceeds a minimum limit which depends on the working air pressure. With for example 6 bar pressure the critical minimum load is equal to F6. Values for other pressure level will be given on request. 4 Pneumatic operating volume. 5 Proximity switch holders are provided for standard proximity switches M12x1 shielded and with a nominal switching distance of 2 mm. For easier service, the proximity switch holders have a positive stop and are preset when deliverd from the factory. 6 Port T is used for pressure compensation (breathing). It is plugged with an air filter element. If, however, moisture or aggressive media are present, a hose instead of the filter must be installed to connect the device with clean and dry atmosphere. 1 2 3 4 Type Ident.-No. d M p F6 H D Z X A HA w L1 G1 T1 L2 G2 T2 AG VL HL H1 H2 G mm kN bar kN mm mm mm mm mm mm mm mm mm mm mm mm cm3 mm mm mm kg KSP 16 KSP 016 01 16 2,5 3,5 2 114 96 35 5 78 36 50° 55 M6 15 65 M6 10 G¼ 10 17 91 88 3 KSP 22 KSP 022 01 22 5 3,5 3 137 120 40 6 104 37 40° 60 M6 15 80 M6 10 G¼ 15 25 115 120 5 KSP 22 KSP 022 02 22 10 3,5 3 137 120 40 6 104 37 40° 60 M6 15 80 M6 10 G¼ 15 25 115 120 5 KSP 25 KSP 025 01 25 15 3,5 4 142 140 45 6 114 37 40° 70 M8 20 90 M6 10 G¼ 30 24 120,5 125,5 8 KSP 28 KSP 028 02 28 20 3,5 7 173 184 50 6 118 40 30° 80 M8 20 90 M6 10 G¼ 40 43 148 153 12 ød f 7 / h 6 øD HL øZe 8 L 1 øA H1 6 x 6 0 ° 3 0 ° w AG T1 G1 X - 0 , 2 øL 2 T2 H H2 HA 4 x G2 Port: release pressure see 2 Port: pressure compensation see 6 Proximity switch port:1 Signal „Load secured“ see 5 Proximity switch port:2 Signal „unclamped“ see 5 L T 1 2 Load direction Attachment side for attachment parts Technical Data Sheet TI-B11 Safety Brake KSP General information, particularly regarding purpose, function, choosing right type and control is provided in „Technical Information TI-B10“.
