Unfortunately not the same lift Grane, but I can see the weight of the boundaries of the equivalent. This model which is pretty close but still different than mine, I crossed the support of the welded pipe and the attachment model bolt fitting and flattened pipe.
I was thinking of buying a new slightly longer dingy which, of course, weighs more and therefore the matter is thinking about me, it's worth trying a little bit to add weight to the old digy and see if the lift Grane's future weight can withstand. Hydraulic lift Grane would be cool, but unfortunately so expensive.
