Manually assisted pneumatic toggle presses:

Manually assisted toggle presses are used when, due to the special nature of the workpiece, it is not initially possible to use both hand for two-handed operations and yet a large compression force is required at the end of the working stroke.
With NP manually assisted pneumatic toggle presses, safe working is possible in these circumstances: the ram is brought to the pressure position of the stroke using the hand lever and workpiece is then held by the force of this lever. A sensor registers this position. At the same time, the workpiece can be released and a button pushed using the other hand, which then initiates the power stroke.

These models are available with a force of 20kN and 40kN.
