(08//07)
The overhang support (A) must be installed to
utilize the machine's full punching capacity.
Avoid serious injury. Never
punch a hole requiring more
than 42 tons of pressure when
the
overhang
support
is
removed.
When the overhang support is removed, as shown
below, the punching capacity of the machine is
reduced to 42 tons regardless of the rated
maximum capacity of your Ironworker.
The overhang support has been removed in this
photo. When the overhang support is removed the
punching capacity for all models of the
Ironworker is limited to 42 tons. This photo
shows the stripper in the open position. Never
operate the machine unless all safety guards are
in place and functioning.
Calculating Punching Tonnage Requirements
There are three primary variables in any punching
operation: the material's thickness, the type of
material (tensile strength), and the size of the hole
being punched.
A quick-reference chart for punching round holes
is provided on the following page.
Avoid serious injury. Never
exceed the machine’s punching
capacity.
