Hydraulically Released  Spring Applied Brakes

There is a variety of possibilities to use hydraulically released spring-applied multi-disc brakes in the stationary and mobile sector, also combined with hydraulic motors. The brakes can be integrated in the oil circuit of the motor. When starting the hydraulic motors, the brakes release with oil pressures of 15 to 38 bar. Thereafter the full system pressure up to 320 bar can be connected. The brakes can be used in wet and dry operation. With failure of the oil pump, an emergency release is possible.

Actuated by spring pressure. Released by D.C. (by built-in rectifier direct connection to  A.C. possible). Delivery incl. fixing screws, completely mounted and adjusted. Torques 2.7 to 10000 Nm (higher torques on request) Dry operation Outer diameter 91 to 750 mm Two friction faces High torques with smallest dimensions High heat capacity Free from residual torque in open condition with horizontal mounting Free from axial force Requiring less maintenance Simple handling

Pneumatically released spring-applied multi-disc brakes with or without pneumatic motor  are used in all sectors of engineering. The brakes release from 5 bar. Thereafter the system pressure of 10 bar may be connected. Application in wet and dry operation possible. Torques from 30 to 13000 Nm (higher torques on request), Air pressure for release from 5 bar, thereafter the system pressure of 10 bar may be connected, Application in wet or dry operation possible, Outer diameter 105 to 710 mm

Spring-applied, released by D.C. Torques from 25 to 1000 Nm (higher torques on   request) By selection of suitable friction disc combinations wet operation or dry operation possible Outer diameter 114 to 255 mm Less residual torque in released condition, also with horizontal mounting No axial force Less maintenance Simple handling

Spring-applied. Operated via a special control unit for connection to A.C. When providing 1 brake calliper to the brake disc only, pertinent reaction force as radial force on the horizontal shaft to be braked - other mounting positions on request. When providing 2 brake callipers at 180 degrees apart, no reaction force. Less maintenance - simple handling Torques from 105Nm to 25000 Nm Brake disc outer diameters from 250 to 2000 mm Dry operation Smallest assembly space Highest heat capacity Strong construction

Electromagnetic single-disc clutches and brakes. Engaged by 24 volts or 110 volts D.C. (others on request). Released by spring-pressure. Combination with a flexible coupling also possible.Torque 210 to 12000 Nm (higher torques on request) - dry operation Outer diameter 255 to 880 mm With or without sliprings High heat capacity One friction face only No residual torque in open condition Backlash-free Free from axial force with shaft/hub clutch With shaft separating clutches less axial force with engaged clutch Simple maintenance

Pneumatically operated multi-disc clutch

Engaged by compressed air - axial or radial supply through the shaft. Opened by spring pressure (in special cases vice versa), free from axial forces requiring less maintenance small teeth backlash with the discs  excess service pressure 5.5 bar torque 120 to 60000 Nm (higher torques on request) wet operation or dry operation possible by selection of suitable disc combinations outer diameter 114 to 640 mm several friction faces - low residual torque in open condition small dimensions high torques high heat capacity

Engaged by hydraulic oil, axial or radial supply through the shaft, opened by spring force (in special cases also vice versa). excess service pressure 16 to 24 bar torque 200 to 100000 Nm (higher torques on request) wet operation or dry operation possible by selection of suitable disc combinations outer diameter 114 to 640 mm several friction faces low residual torque in open condition small dimensions high torques high heat capacity small teeth backlash with the discs free from axial forces requiring less maintenance

Engaged by 24 volts D.C. (others on request). Opened by spring force (in special cases also vice versa). torque 12.5 to 10000 Nm (higher torques on request) wet operation or dry operation possible by selection of suitable disc combinations outer diameter 95 to 560 mm small dimensions high torques high heat capacity free from axial force with or without sliprings maintenance-free or simple handling requiring less maintenance several friction faces low residual torque in open condition small teeth backlash with the discs

Engaged by 24 volts or 110 volts D.C. (others on request). Released by spring pressure (in special cases also vice versa). Torque 20 to 100000 Nm (higher torques on request)  Wet or dry operation Outer diameter 60 to 850 mm Smallest dimensions with highest torques Torque transmission through form-fit crown gears Engagement at speed zero only No residual torque in open condition Small teeth backlash at the guiding teeth In relation to the specific series, zero backlash possible With shaft/hub clutch free from axial force With shaft separating clutches less axial force with engaged clutch With or without sliprings Maintenance-free or less maintenance required Simple handling
