Brake Press Guards
Brake Press Guards
(OP)
I was wondering if anyone has thought of a clever guarding technique for this piece of equipment. Having light curtains installed is simply not an option for our company seeing the costs involved. The guard should allow operator freedom, while keeping limbs and digits inaccessible from the machine, or tripping the circuitry some how to raise the break. I was wondering if anyone could help. Thanks.

I have seen a single-beam optical device which shines along the length of the tooling that is specifically designed for press brakes. I don't recall who manufactures it. As I understand it, this device is approved in Europe, but I don't grasp how it can comply with the safety distance requirements here.
Small workpieces - best thing I know of is to use light curtains without blanking (sorry) and build fixtures that can hold the workpieces without requiring the operator to hold them. Big workpieces - you can get light curtains from ISB, Siemens, Leuze lumiflex, and elsewhere which can have a programmed sequence of beams that are allowed to be broken.
If that press is hydraulic, Z142 requires redundant monitored valves, monitored restraint devices, and control-reliable everything. It will be really, REALLY expensive.

That arm pull back device should be banned everywhere, it opens up more worms that it treats.
When I operated a brake, I always put my big foot under the bar as far as I could wedge it during alignment. Not a great solution but the plant owners weren't going to do anything to correct the hazard. Of course this was way before light curtains were even conceptualized.
