This press combines hydraulic and mechanical operations
into one system. Hydra-mechanical
presses consist of two basic models: one is actuated by a mechanical
treadle/pedal and the other is actuated by an electric foot switch
or palm buttons with a complete control system.
The operator is responsible to feed or place the stock on the
bottom die properly and activate the press cycle with palm buttons,
foot pedal, or a foot switch.
A hand or other body part near the point of operation
during cycling can result in severe injury.
- Operating controls, especially foot pedals, introduce the possibility of accidental cycling.
- In forming large pieces, the operator must hold the
stock and cycle the press with a foot
pedal. As the work stroke begins, the stock will move up or down, creating
