Dragon Cam versus Weight of Medium Sized Car Video

© DMM

There is nothing like seeing theory in practice to fully appreciate the facts and figures behind how well a product works. DMM's Technical Director, Fred Hall, had the idea of cutting a parallel sided slot out of a 1.38 tonne boulder, placing a Dragon Cam 5 in the slots and then lifting the boulder via the Dragon Cam.

At rest the weight of the boulder is equivalent to a static force of 13.8 kN, but as soon as the weight starts to be lifted the force exerted on the cam increases above that figure.

All Dragon Cams are certified to a 3 sigma 14 kN, but in testing to failure they far exceed that figure.

Watch the outcome of Dragon Cam versus the weight of a medium sized car here.

It is worth noting that the cam still works perfectly after having been used to lift the block.

The Dragons are in the DMM warehouse and about to be shipped. They should be with UK retailers early next week and with export customers the week after that.

Intresting but not really suprissing, that is their specification. There looking really good though, just a real shame thay had to make a compramise regarding aid climbing. I have been looking at the american sites and there is a genral concensus of - no thumb loop, no good for aiding. Shame i would love to own a set.

Quite mpressive, especially as it looked slightly undercammed - I would have gone for the next size (half size?) up! Chris

That slot don't look parallel.

Presumably if you really wanted, you could just larks foot a loop of 5mm cord around the stem above the thumb rest, and use that to clip in short. It only has to hold body weight after all.

I'm impressed by how strong the little forklift is!
