Abstract
To prevent from industrial accidents caused by power presses, protective measures required by global safety standards, such as ISO12100, EN692 and EN693, shall be applied in Japanese industrial fields. The following protective measures shall be applied: 1) Standardization of safety guard, 2) Elimination of key-switch to bypass function of protective devices, 3) Blanking system for two-handed operation, 4) Effective protective devices during inching operation, 5) Guarantee of protected heights by protective devices — light curtain, 6) Protective device for sides of machine (fixed/movable guard). The inquiry into analysis has also revealed the development of new safety systems designed for servo presses, press brakes and large-sized power presses.
