There are many varieties of hydraulic presses performing many
different processes. Hydraulic presses can normally be stopped at any point in their
cycle and the force exerted by the dies can be varied.
Operating speeds are normally slower than mechanical presses.
However, because of their slower operating speeds they are normally not fully
automated. Integral operator involvement is necessary,
increasing the number of safety hazards and the need for
applicable safeguarding.

Operator Involvement
The operator is responsible for feeding or placing the stock
on the bottom die, seeing that it is properly positioned,
activating
the press cycle with a pressure control switch, and removing the
completed part.

Point of Operation |
-
A hand or other body part near the point of operation
during cycling can result in severe injury.
-
Material handling is hazardous as material may have sharp
edges, be slippery or heavy.
Solutions:

Additional Safety Measures |
-
Operating controls should be located away from
the die area and should employ dual
palm buttons.
-
If a
foot pedal control is
used, it must be guarded.
-
An emergency stop button should be
available with easy access to the operator and
a main
power disconnect switch is needed.
-
Power transmission components are normally located
away from the operator; however, hydraulic
pump/motor arrangements should be enclosed. [1910.219]
-
Work area should be kept clean to prevent
slipping or falling hazards.
