Thread: Home made jib crane with photos

To every one that has posted thank you, for the compliments,

Mathew g and Jatt, (fellow hauderer's)
I think there are still many hauderer's out there like us, but in this disposable world with it's smaller and smaller house blocks (like has been said) and landlord/council regulations it's a dying thing.
There is nothing better than not having to go out and hunt down stuff for a job your doing. Most of my designs for building things come from what I have on hand laying around and I work around them. We have 3/4 of an acre's with a house and 4 sheds, and my wife has 2 horses. I am trying to convince her that a another big shed would be great in the paddock instead of the horses. Maybe one day but not any time soon.

Steran50,
Sounds good do you have and pictures of your overhead gantry?

Thats the same one that I mentioned in post 20. I new there was another place I had seen it in pdf, thanks. I think that is a good design for a Gantry crane. I am going to copy that one my self in the future, only with a heavier capacity.

As long as it does the job is all that matters. It's amazing what a coat of paint does though, mine didn't look much with out it.

Proud to say I know the guy and he is one of the cleverest people I have seen with his hands . He has helped me a lot . The reconstruction and modification job he has done on his Hafco mill is also outstanding work .
Well done Dave.

Thanks Retromilling
We all learn from each other, as I have learnt things from you.

HI, I do have a couple of Photos when We were building the Shed. I will try and take some more Photos over the Weekend of the Gantry. Then I will have to work out how to put Photos on this Website.

The shortest way to do many things is to do only one thing at once.

Nice work Dave J
Your have inspired me
Cheers mate.

Great work Dave - very professional.

This posting inspired me to replace my block and tackle that I used to hoist indexing head and indexing tables onto my mill with an electric hoist - figured in later years the block and tackle would not be possible so why not make it easier now.

I purchased one of these cheap chinese 250/500Kg electric hoists on ebay but it is VERY noisy and even worse when lowering under load. I certainly would not be game to put 500kg on it - trying it out on my 100kg or so of indexing head had me spooked enough to send it back.

How quite/noisy is your or am I just overreacting to what sounds like gears about to jump a cog!!

Even if they replace it I had to pay the $26 postage to return it and if they don't agree that it is stuffed I have to pay again to get it back - this exercise is proving a bit more expensive than I had planned. Just a word of warning to others going this path.

Thanks in advance for comments

Are those electric winches a Chain drive to the hoist.

Not sure what you mean but if you look at the pic IM000211 of Dave's winch you will see - appears to be a simple reduction gearbox between motor and winch drum then wire cable to the hook. As I didn't dismantle it unsure if gears or chain but I had assumed gears. As no-one appears to have complained of them being noisy I also assumed that they were normally quiet.

Hi BB,
I am almost positive there gear drive, when I push the button on mine I here a loud clunk as it engages and then you hear the gears after that while it's winding out or in.
If it is sitting on the bench it will try to pull it self over if you push the button.
I plan on putting extra pulleys top and bottom to slow it down more, as it is a bit fast for putting things down on the mill.
I had a look on you tube for a video for you, this one sounds like mine.

I forgot to mention that I have lifted nearly 440kg with mine. It was when I fitted the adjustable feet to the lathe, that I made a few weeks ago. I was skeptical like you, but it did it and didn't brake the winch. I think it has some sort of dog clutch for safety. There is one bloke on ebay that sells parts, it's the same one that sells the motorized trolleys I think.
Dave

Just when you mentioned a Cog ,I have never come across a Cog in a gearbox.

Hi Pipeclay,
I knew what he meant, I have heard "Cog" get used as slang for gears since I was young. What he was saying is, he thought it was about to jump a tooth.
Dave

Thanks Dave
You answered my question better than I even expected - mine was obviously stuffed. The Youtube video sounded like I expected. I should have borrowed a camera and taken a video before I sent it back it was shocking compared to that. I am more assured that I should have no problem getting a replacement.

Thanks again
BB

Glad that eased your mind about the noise. Thats the gamble everybody takes with ebay, but the seller usually pays to have a replacement sent back to you. I would get onto them about that and if they don't pay the return freight, leave them negative feed back for selling faulty goods and then charging you postage both ways. It will stop a few people buying from him in the future.
My wife bought me mine from ebay for Christmas 08 and the warranty was only 3 months. I checked it over and hung it from my engine crane to give it a go when I got it, but never used it properly until this Christmas, so it had me worried. I haven't had any problems with it yet, and haven't heard of any one else having problems with them except for yours.
