Power Press: Provides barrier between danger area and operator until completion of machine cycle. Another potential application of this type of device is where the gate is a component of a perimeter safeguarding system. Here the gate may provide protection not only to the operator but to pedestrian traffic as well.
Advantages: prevents operator from reaching into danger area during machine cycle; and provides protection from machine repeat.
Disadvantages: may require frequent inspection and regular maintenance; and may interfere with operator’s ability to see work.
On some machines, gate may only prevent access on the downstroke. This may increase production by allowing the operator to remove and feed the press on the upstroke.
When gate is lifted, interlock switch prevents baler from operating.
