Lifting Frame
Posted: Mon Nov 09, 2020 2:12 pm
Hi all, as my next part of the project is to get the boat suspended in the air, I have now started construction of the lifting frame. Nothing turns out easy, but work around 's can always be found. Here are a few pic's to show you what I am doing at the moment.
First I made the base of the upright posts to enable them to be dyna screwed to the garage floor. The posts are 90 x 90 x 3.2 mm and the welded on brackets are made from 50 mm x 5 mm Then I made the top section including the hangers. The bar of the hanger is 20mm round bar and the sides are 50 x4 mm This was all going swimmingly until I tried to fit the ratchet end of the strap, only to find there was not quite enough clearance between the round bar and the post to have the hooks sitting correctly on the bar ( Bugger) Also made the bracket and welded it on to the post to be able to bolt on the top cross piece which has nuts welded to each face to be able to bolt it on all four faces. the top bar will also be 90 x 90 x 3.2 and will have diagonal braces bolted. I found that if I undid the bolt that held the ratchet to the webbing, that I was then able to slip the webbing down through the gap between to round bar and the post enabling the bar locks to sit the correct way around as well as have the ratchet facing the right way Now I have one post finished, just three more to go and then assembly. Bolts will be welded to the outside top and bottom of the posts so that diagonal steel bracing can be fitted as well
More photos to come
The beauty of this system is that I will be able to park the boat on its trailer between the posts. I will probably leave the two nearest the wall of the shed there and dismantle the other two and store them. Anyone in Tas who will need the services of the lifting frame will in future be able to bring their boat to my place and use the frame as required
