any engineers here?
if you put 600 lbs of people on the outer edge of that tech, now many lbs are transferred to the cable mount on the wall? because its a 45 deg angle, does it amplify the weight on the wall?
The COG of 11' TC is about 7 feet from rear jacks (pivoting points).
So assuming camper weight 4000 lb, it would take 4000 lb of human load on the rear of the patio to start tipping it over.
Manufacturer rated it at 1500lb, so we have safety factor of >3.
As for the cable tension, it is 1500 lb x (sin of 45degree) 1.41 = 2115lb for 2 cables, assuming all people stand on the edge of the deck.
For 600 lb of people each cable tension will be 423 lb.
The site says each cable is rated at 1200lb, probably with safety factor of 3 as well.
I assumed cables are mounted at 7' distance length at height, when the shorter mount will increase cable tension, but then not likely you will have 1500 lb of people sitting on the rear edge.
Realistically I think the wall mount will be the weakest point, but they reinforced the beam there.
