Boat hoist build idea

[W.olly]

Well i ma cracking up here now with nothing to do that interests me so i thought i will crack on with this boat hoist for my new when it comes home.
The boat weighs around 2200kg / 5000lb i want to be able to lift it of in my work pound to get it off the trailer. I need to think of another earner along side my boat works services. so as the trailer is good boat transport is the idea.

I have done this amazing tech drawing of the idea . Just need to check on steel spec, concrete pad size etc. i was going to go with block n tackle but i reckon electric winch`s would work better.

There will be four of the posts, so another pair at the other end spaced out correctly.

Each post will have a 2000ld winch fitted

Once lifted it will be lowered onto the usual blocks and supports so i can work on the boat when its home.

What you tech folk reckon any alterations, and i dont really want any cross beams inplace.


The boat

PS i did think of converting a 4 post ramp aswell lol

Can’t you use blocks of timber/sleepers and jacks?

thats the hard way kida, i have done all ways in the past

its only winching on one side of the strap it will pull over to one side and tip the boat sideways

Why when there will be a winch each corner of the four, same as a proper boat hoist

that's why I deleted my post couldn't work it out

the foundations need to be deeper/bigger to resist overturning

by how much ?

In my opinion it’s Not worth the investment , the boat is just about 2250 kg so easier with Jack’s and blocks.

 

[waddycall]

Could the uprights be linked at or below ground level with a steel beam or something to reduce risk of the footings rotating?

But you dont know the whole reason why i want to do it. aswell as a project its more than that kida. If you want to safely and quickly lift a boat this is easier and quicker or boat yards would just use blocks etc etc

Thats the trouble , it could have one below or at ground maybe, so bolt each leg to the cross beam then concrete in ?

Interesting idea.

I'd go taller with cross beams.

Less foundations.

2200 kgs, 600 kgs per column+-.

it's not enormous I suppose. But it will want to pull in I suspect.

deep pilings and lots of concrete...

Or...

Have the pilings joined under the ground with 45° gussest / channel as you've done above?

Just thinking out loud.

I'm no structural engineer, mind you.

Join the posts together at the top - crossbeams - far stronger and no need for deep foundations.

I would consult an engineer, someone with knowledge of what you want to achieve.

Small investment now will pay dividends in the long run

Plus as its lifting equipment LoLer will apply along with PUWER

LoLer and PUWER ? Parm?

LoLer and PUWER ? Parm?

LOLER - Lifting regs, will require statutory inspection of lifting kit

PUWER - Machinery regs, will require maintenance plans etc etc etc

Great name for a boat! Only just spotted that.

I assume it's in his garden, and he's not starting a boat yard?

Really?

I'd phone up a local building company, with a lorry and hiab.

100 quid an hour?

Be nice to have a boat hoist though, nice idea.
