mechanical brake for axis

[ansyolitico]

Hi.
what solutions do exist for emergency blocks on reversible belt axles?

I have a vertical axis, we are evaluating whether belt or screw, has a nice race about 2000 mm with a considerable weight, about 500 kg. to secure it in case of electrical failure or black out which solutions exist?

I've always seen them do it with electric brakes put on the pinion that was taken with the rack. not having the rack.

I had imagined myself classical braids braiding braid style auto/moto, in which there an excited coil that makes strength on a lever on the spring pad, goes in emergency, the coil disarms and the crayon closes on the z structure, but one thing so on the market does not exist, at least I do not find it, and if you should realize I don't know where to take the reels, and above all I don't know if it is feasible since the coil should win a good force. also building a lever effect I have no idea if then I'm in bulk and weight

I'm the most common solution. Other times I used systems The Side o party party using a different principle. I would avoid putting the safety brake upstream of the moving trolley (for example on the belt pulley) because in case of breaking the transmission would not be effective.

are all negative brakes. with air or oil there is cream. but there are a lot of manufacturers of negative brakes that in the absence of signal close.
If you can put a counterweight to lighten the inertia.

You can think of putting electrofrenes on the axis.
See you qui.

Unfortunately my z axis is on another axis, so I need to have as little weight as possible, so I can't put a counterweight.

I can put air cylinders to compensate for the weight and maybe use them also as a locking system in case of black out, but I also wanted to put pliers as additional safety. I don't want to kill someone

Thank you

In this case, remember to put a servo-valve that keeps the pressure constant in the cylinder chamber when changing the position between the shirt and the stem, otherwise the risk is to break the gearboxes.

as a very basic safety system sometimes puts a vapor of piloted restraint (e.g.: hgl fist) that prevents the emptying of the lower chamber even in case of emptying of the compressed air line resulting in an emergency.

look also these, could be a solution.
