HOME | Products | Pull-back Safety Device


This pull-out safety device is a device that pulls a string using the descent movement of the slide and pulls out the worker’s hand with the wrist band out of the danger limit.
Since it performs mechanical interlocking with descent of the slide, it is effective against unexpected fall of the slide.  Although it is a primitive mechanism,  it is a reliable safety device.  The DT/DF type safety device meets the press safety device structural standards and has passed the Ministry of Health, Labor and Welfare Test.


1.Easy to install.
2.Since the hand is pulled by force according to the movement of the press, it is possible to secure safety even in the case of a missing pin, or accidental drops.
3.Less shock on hands.
4.When changing dies, when not working with the press, you can fold arm of the pull-back device, therefore it does not get in the way.

**The pull-out safety devices perform reliable movements, but at the same time it is necessary to adjust strictly.  Especially if you do not adjust the length of the string securely, safety functions may not be able to be exerted at all.  It is very important to adjust the length of the string for each worker.
