Presses are among the most dangerous for the operator machines. Therefore, for mechanical presses called retention of ram facilities are required. This will ensure that even in case of failure of all the energies of the press ram is held in position and so there is no risk to the safety of the operator. The hydraulically actuated clutch-brake combination KB40 / 2 - KB 300 / 2 by Herion is effective in any plunger position.
So far, partially positive solutions have been offered on the market can lock only in the upper plunger position. This frictional system with integrated hold-up device offers a small footprint, simple design adjustment, no additional attachments and assembly costs, easy control and the fact that no change of accessories is necessary.
Operators of presses save valuable time and thus production costs, since the press room can be entered after each stop and completely independent of the plunger position. In addition, the wet-running friction system permanently ensures largely wear-free operation.
The clutch / brake combination with 2 brakes can be used on a variety of mechanical presses. Holding torques from 11.175 to 180.000 Nm are available for the realization of the ram maintenance.
