I have repaired, modified, and rebuilt high capacity hydrualic
presses. I did this for a living in a previous life. Hydraulic
presses are dangerous. As the press capacity gets to 50 tons the
dangers become very significant. I am talking about broken limbs.I
have worked with machines which used hydraulic presses in a portion
of their make up. These machines come under strict OSHA codes. If an
employe is indjured on a machine that is not built compliant to OSHA
codes, then the owner / manager could be taken to court. This is no
joke. I have rebuilt 50 Ton hydrualic presses retaining only the
pump, cylinder and name plate.
I would recomend that anything above 30 ton capacity hydrualic
presses should have guards in place to prevent flying projectiles
from striking anyone in case of failures. A guard should be both
efficent and easy to work with. Eye protection and a face shield
should be considered as vital for 20 ton machines. Electrical or Air
powered machines need to have a well considered tag out / lock out
proceedure. The 50 ton powered machine had broken a man's leg when a
part being pressed flew over 10 feet, striking the victem who was
just walking by. The near by 100 ton press, no one would use.
These machines harness unseed and little appreciated forces to do t=
heir work. I would be hesitant in fabricating any press rated over
50 tons for use in the jewelry trade. However i would fabricate one
rated at 30 tons. It would be guarded and to code. I would also wear
protective lenses or a OSHA face guard. I am accustom to having
worked in an environment which could kill or cripple me. Please be
professional. It is easier than being hurt Journeyman AFL CIO
