    Appendice Parking brake PB series General specifications The parking brakes of PB series are spring applied and hydraulic released multi-disci brakes (steel discs alternating with discs with sintered bronze coating), to be used in combination with planetary gear reducers of EP series. They are not service brakes and cannot be used in dynamic conditions.
  • Page 109 Functioning of PB parking brakes Brake closed When no pressure is applied to the brake (0 bar) springs (1) apply a force to the piston (2) which lock the discs (3) and produce a nominal braking torque equivalent to M Bstat Brake opened Above the pressure of 0 bar, the piston begins to compress the springs and the brake progressively reduces...
