Louisville Ladder Pump Jack Installation Video 

I know lifting the shingle on that brand new roof would have been hard

Vou fazer um pra mim de protótipo. Se der certo vamos compartilhar.

Detach the brace from the pole. Pump the jack above the brace. Reattach the brace underneath the jack.

@@jharris4546 Ok, thanks for that. So the 48' poles are safe enough to have the stabilisers detached for a while! I guess to be safe you would only remove one stabiliser at a time and raise the platform past that missing stabiliser, so that the platform temporarily sloped and then do the same with the other end of the platform, to level up the platform and therefore keeping things a lot safer than removing all the stabilisers at once.

@@johnsomerset1510 They really do work quite well. You could drop all the mid brackets, pump up, then reattach them with no safety issues. Or leave the mid brackets off. Work up the lower part of the wall, and when you get above that mid point, then attach the brackets under the pumps. They do take some getting used to, but they're quite steady. In the 70s and 80s I used to work on triple-deckers in Worcester MA off of posts made out doubled up 2x4s. When you got high, the moment of the rotation from the weight on the planking (also wood) really caused the posts to bow out, and the planks would bounce around as you worked. Those mid-brackets were literally life savers. Any of the aluminum setups are WAY safer than the wood.
