This is a story, an inspiration, a challenge and a thread.

How do you build a device that can lift a 2 ton speed boat out of the water by a hand operated winch?

That's exactly what I'm thinking in the picture below.

This is what I came up with.

first things first, I rented a space at the iron market ...
N2000 per day.

Hello boss, first thing you need a welder, of which I'm one, so you can call me on 07033291983, I'm in PH.

I love challenging stories

Next thing was material selection. since the lift was going to be permanently in salt water, it was important to make sure all parts were galvanized steel and stainless steel. even electrodes for welding were stainless steel electrodes.

another important consideration was the capacity of the winch. since I was designing a 4 cable lift, the minimum winch capacity I would need is a half ton winch in order to lift a 2ton boat.

so when I saw 1ton written on that winch. I knew it would hold up.

That's the boat I'm trying to lift by hand.
Failure means I'll have to refund almost 2m Naira. where I wan see am?

Na lie! first thing I need na empty space

Selection of stanchions complete. all galvanized and imported materials. so corrosion will hardly set in.

welded the main frame ensuring all the corners are square.

Both main frames now complete. checkout my James Bond glasses �

Next, assembly of main frames to see how they fit together.
That's how people were just passing up and down disturbing me

Now painted and reassembled at the rented space for the real battle to commence.

Na play we dey play since trust yourself not me

Nice innovative and informative thread. Just in case, I do hot-dip metal galvanizing that meets international standard and would be of assistance if necessary. You sure have a lot on your hands but I'm certain experience and perseverance would guide you. If you were in PH, I could have helped you with some equipments(Forklift, metal baths, angle irons) you might need for free. I love fascinating projects as these! I wish you all the best!

PS: Seems like you're in Lagos. If you know prospective clients for metal galvanizing in Lagos, we could do business as I'm working on opening a branch of my factory in Lagos this first quarter of the year. Proofs of work are available and I'm available for meet ups if and when necessary.

Cheers

Chief, more pictures abeg

Good morning people, I had to sleep, but now that I'm awake ...more pictures coming. sit tight

thanks, hnmn free angle iron? I would jump at that any day. another client wants another boat lift this January and his concept is even more challenging.

Next, had to mark the transfer beams and load beams for installation of rollers for the lift cables.
Note: even the winch cables had to be galvanized steel cables minimum of 8mm.

Mounting the winch.
The thing about integrating most off the shelf components is that most times you chose your dimensions and parameters from existing features you find on the component you bought.

so this design and construction of a boat lift, I did it without any design drawing. everything was plan as you go. I prayed a lot because, imagine working without a drawing for something as complex as this and if I fail I'll have to refund a lot of money.

Marking out the holes for the U-bolts that will hold the winch in place.

the winch must not slid down the stanchion when lifting the boat else I'm in trouble. we will mitigate that when we get there. just know that for now.

Next I mounted the winch on one of the stanchions I made 1 ft longer than the other 3 stanchions.

this mounting is just for testing purposes. the final height of the winch has to be 1m above where it is now.

may it interest you to know that the depth of the river where the boat lift will be installed is about 2m at high tide and 1.4m at low tide.

so 70% of this lift will be submerged in water beyond visual range.

Gave a tailor money at the market to make a tarp to cover the winch at close of work everyday so rain water doesn't enter inside. this was in October and it was still raining like mad.

Here after installing the transfer lines and load lines and hooked them up with the winch...I was wondering if it will work.

Lovely thread, front page material!

Now if you go to Owode and you never chop their ewedu ... it means you no come work today

I ate it everyday for 3 weeks

Testing to see if it can lift me and the ewedu in my stomach...

like play like play my stomach was just lifting up until later my whole body started to follow

Before I knew it I was 2m in the air .....hnmn that's a good start. at least I weigh about 75-80kg.

2tons is what we want to lift with this device so enough of the play play

Lol. Yes I could give you free angle irons if you were in PH, many clients who can't pay the balance of their jobs due to many reasons(including but not limited to politicization of the jobs) abandon their metals in my factory so I have lots of angle irons,U-beams, flanges and even ladders dusty in my factory for many, many years. Most of these clients aren't even operational any longer or have moved out of Nigeria so there's really no breach of contract! Good to know you have another project this January. I used to galavanize metals and bolts for a huge Oil Servicing Company which also assembles boats in PH so I'm quite experienced. I have also done jobs for major IOCs here ranging from Chevron to Shell to Addax to Mobil etc. I'm honestly very impressed by your project and would gladly accept any galvanizing jobs 100kg and above. Do update us regularly on this thread about this project as I am now a keen observer. You go win las las..

Cheers
