I have just started in the Meat industry having working in Engineering. The use of vertical bandsaws is very much hands on due to the speed in which the product has to be processed.

We currently don't have an issue but I'm looking at ways to improve the safe use of the bandsaws.

Does anyone know of any companies that do special jigs or push sticks that might be of help?

I doubt that industry would go for push sticks, the operation would then be too slow.

Check out Bladestop though - reacts to coloured glove in safety zone and stops blade in 15ms.
Impressive.
PUWER surely dictates that these MUST be fitted?

I've looked into this in the past, and it's not as simple as "fitting" a bladestop system, certainly not at the time i was making enquiries, the system was not able to be retrofitted to our existing bandsaws.

Understood, and I don't presume to know the fine details of the system. The energy dissipation in bringing that reciprocating blade to rest almost instantaneously will have to go somewhere -there may be a sacrificial element to the required machinery.

Better than a sacrificial hand though......

Incidentally, for those with a spare 10 minutes, there are some weird and wonderful videos on Youtube looking at kick back on circular table saws, some interesting innovation work and.............some really dumb people. Particularly the guy who sets out to recreate a kickback!

You can't retrofit a blade stop system, though I would expect the blade to stop in <10s or < or = to the run up time of the blade.
PUWER requirements for wood working bandsaws, so I don't see why it should be different for a meat saw.

As you say Ron, the dissipation of energy in the near instantaneous stopping of the blade has to be dissipated somewhere.

I was at one time in negotiations with a company called SawStop in the USA about bringing their machines into the UK and getting them CE marked, but this did not prove successful, they work on a similar principle, and have sacrificial parts and specially designed systems to dissipate the energy.

I think that you can get trolley systems for meat saws, but this is verging on the limits of my experience.

Again, you can get chain mail gloves, but, I would caution on the use of a mechanically strong glove in case it were to get caught in a toothed blade and increase injury severity by drawing in.
Are they using typical meat & fish toothed blades for cutting bone, or are they using band knives.
With band knives you would be OK with chain mail gloves.

The issues you will have are the rates of production vs the increased time taken to implement mechanical assistance, which will also reduce dexterity and reduce the quality of the cut, as the experience and dexterity of the sawyer is what give the quality of the cut.

You could look at knives rather than blades if you are not bone cutting, nor cutting frozen.

Thank you for the replies

Chainmail wouldn't work due to the increased risk. Think the blade stop is a possibility but would need to see if it would fit the bandsaws we have

Or they could invest in truly automated equipment - just seen a documentary on Danish bacon production with next to no butcher's involved in turning the carcas to meat cuts.
