Read the rules!!!

Seriously now...you can download them, and should be aware of them.

He does have a good point though.
We opened this can of worms a few months ago and im not sure what the outcome was.

I have an electric lifter which had covers over the sharp edges, in terms of a safety bar to physical stop it from moving i think it wasnt needed as the lifter was electric, the Removable Link was good enough as the lifter would not move without the link.

So i dunno what the answer is, maybe someone from the FRA wants to confirm the answer, but i know Big Nipper, Storm 2, myself which electric lifters have not needed a safety bar to stop it from moving. But safety covers to cover sharp edges yes as always.

Stu, you are correct

We have a locking bar for our lifter & crusher, as I read the rules they are needed on any type of moving weapon.

I suppose common sense dictates to use something to lock up movable parts with anyway.

I dont use a locking pin in ploughbot, but due to the way it works it is permantly locked anyway untill power is given. If i used something like spur gears or 4 start worms so that its possible to move the lifter without power then i would use a locking pin.

I stand corrected - missed this one.....
F.R.A International Build Rules & Guidelines 2007 Para 1.5.5.
All Robots not in an arena or official testing area should have secure safety covers over
any sharp edges and restraints on any active weapons or pinch hazards.

i have a hydralic lift/crush which will not work without power, i dont think a restraint is needed on my machine, but i still strap over it, i would have thought its mainly gas powered weapons. i think you should just do it then at least your covered.

[big_nipper]

Lifter safety

But gas powered wepaons will not fire without power either as the valve wont operate!

Come on guys use common sense.

The expression we need to focus on in this discussion is: pinch hazards. Thus, what can move should be restrained lest it hurts someone.
I hear nobody complaining that wheels should not touch any surface, even though they cant spin whithout batteries attached - for they can still spin on their own and are hence unstable. The same applies for weapons.

Im keeping well out of it, as i was involved in the discussion mentioned by stu.

Adrian, From seeing Kan-Opener, you need one.
From seeing Razer, you dont.
Its the event organisers call at the end of the day I guess.

Heavy weights i fully agree....

Feather Weights you could waver but then we all know feathers are just as harmful. Again the can of worms open was certain teams dont, so i shoudn;t have to, which is the wrong attitude i agree. So in future my lifter will have a locking mech, and advise everyone else to... and maybe this is one thing we need to clean up and come down hard on? Thank god there have been no accidents yet, so why should we slack now.

How do u mean from seeing Kan-Opener yes and Razer no? Dont get your line of thinking? Is Razer really that week at crushing? Is it 3.2gs not 3.2tons? LOL

lol,
no, all imeant was that some teams do, some dont, just as you said.
For the Mold event, Ill not fail a lifter robot in tech check while it is a grey area, but in future I prob would... but dont quote me on that. Hydraulic robots i need to take advice on from the FRA rep for future stuff.
