So, what did this to my Ram??

[Smiler.]

Not what you thought eh?

Found this today:







The one the other side is fine.

I've asked the UK supplier the same question.

WTF

[Munter]

BAAAArberians at the gate?

[ShadownINja]

Someone bumped the gate with a car and didn't bother telling you?

Don't think so, the damage to the ram seems to be from a downwards force.

Someone climbing over your gate and put their foot on the 'Ram' bending it. I hope its not the case but quite possible/likely.

Someone climbing back out? Pah, slightly too slow

Yeah, that is the only other option I think.

Even so, it would take a gorilla to effect damage like that.

I'm keen to see what the suppliers have to say.

[GKP]

Suppliers will say 'that's not covered by warranty'.

An adult's full weight on one foot in the centre lifting themselves up could easily do that.

Thats the only option unless one or both of the struts were not screwed in properly.

seeing as nothing looks bent that would be my guess

There is housing over the parts in view which I removed (if that makes any difference).

Does it look like the bracket on the wall is bent or rotated down? (or is there now significant play between the bracket and the ram?) That might give you more of a clue as to the direction of the force.

The ram could have a failsafe design that means that it fails like this in order to prevent more serious damage. Which could bring 'forced gate' back into being a possibility.

The better quality rams should back off if they meet an obstruction.

Looking at the photo it could have met an obstruction while closing but not stopped and kept on trying to push the gate shut.

Have you checked if the missus is in the house? She may have slipped the lead - most likely culprit.

[VEX]

Actually looking at it again, it could have hit an obstruction while opening and kept on pulling.

No, the brackets are fine.

I can't believe that the damage is incidental caused by someone standing on it. The one on the other gate was solid when I pushed down in the same place.

It's an odd one.

The rams are designed to overrun for a few seconds when the gates are fully open or closed.

I'm wondering if there is some internal pressure relief valve which has failed.

The chap from BPT reckons he's never seen anything like it in 20 years, "not possible".

[VEX]

Most rams are not hydrolic (spelling) but worm drives, purely mechanical.

I guess you have mechanical ones, especially if they over run at the start and stop points as this indicated that the (OOOOooooooo that's made me think) way the motors stop is by thermal cutout, ie when the motor gets to hot it will stop.

So by hitting the end point the motor is made to work harder, gets hotter and stops. What if you thermal cut out failed? The motor would keep on winding and possibly do damage like this.

Good quality ones work on reed switches or stepper motors to give a slow start and stop.

Not suprised by the response from BPT either.

Are they part of the evil empire or do the just use them to distribute their kit to our industry?

[VEX]

They are not part of the evil empire, they do that quite well in their own access control world.

Almost anyone can buy direct from them cheaper as well.
