( doesn't mean it is better; just feels better ! ) Personally I'd leave the other two vertical poles long instead and run the lifting member to them. More stable due to being anchored to blockwork and leaves loading access from two sides The diagonals you show in later drawing will obviously help, but I doubt needed for 150kg 1 Link to comment Share on other sites More sharing options...

No, if you're using just 2 poles, like this: But you could do a 4 pole version which obviously would have a bit more stability.

Either a double scaffold clip, or buy another lifting sling and just wrap it around the cross-over and it will share the load through the two poles.

Pocster Posted August 3, 2020 Author Share Posted August 3, 2020 On 31/07/2020 at 18:14, pocster said: I did think that type of arrangement is what you meant. But I'm more comfortable ( i.e. less chance of my death ) with 4 corner posts I can then stick scaf boards across as a 'loading' platform. Also I'm unhappy ( not as in sad, I've drunk some wine now ) with the counter leaver weight. A corner to opposing corner vertical with a horizontal gantry across means the weight of the lift load is central so doesn't need a counter balance ( if I'm wrong I'll die proving you were right )! Getting nowhere with this. Scaf companies being arsey. Tempted by @joe90 original suggestion. All I need is 3 scaf poles . The 'guides' etc. to stop it rotating could all be done with timber ( cheaper and easier to obtain ) I guess even the 'spreader' could be timber??? - bit worried about that crushing and therefore failing.

Ferdinand Posted August 3, 2020 Share Posted August 3, 2020 (edited) I can see at least two Medieval torture devices in this thread. Why don't you just fill it with banzai spikes, cover it with camouflage, and have done with it? Find some sheep and you have homemade mutton kebab. Sod your cellar.

NO, just buy what poles and clamps you want from a supplier and don’t tell them what it’s for,!!,, (have PM a local company near you) Link to comment Share on other sites More sharing options...
Pocster Posted August 6, 2020 Author Share Posted August 6, 2020 If I got a swivel hoist clamped to a vertical Scaff pole ; then there can’t be a counter weight ? . So could I just have as originally planned 1 Scaff pole bolted to the wall right in the corner and use the ‘swivel’ to move a platform around i.e load it not over the hole - then simply swivel round over the drop and lower ??

Risk is the pole bending and or it pulling away from the wall. A diagonal tie back to a strong point able to take the load guards against this. 14 minutes ago, pocster said: Ooooooo .

Just read it throughly - takes standard Scaf poles to provide horizontal arms - then bags of sand I recon to counter weight it ( unless anyone can think of a cheaper alternative) Also , if I need to resell when done will be easier - though something like this I think I would keep .... for parties Edited August 6, 2020 by pocster Link to comment Share on other sites More sharing options...
