advice building jib crane for workshop
hello, I'm a new user I'm Italian, I would like to build a jib crane for my personal needs, for my little garage, it should be high under hook 3 meters long boom 3.50 meters and a modest reach 500 kg is enough, empirically extracting data from tables, I chose a 4-meter high 100 mm HE beam as a pillar column, and a 120 mm x 3.50 meter long ipe boom.
I would have to make the hinge to tie the column to the arm would have advice, thanks, on the boom will flow a chain hoist with manual chain, thanks in advance to those who want to provide giusi suggestions, one last thing I could add a tubular column at the end with wheels to support the cantilever beam, lame gantry crane type? what do you think thanks for the attention look valuable tips to the next

Greetings Athos,
Welcome to the forum.
I have two cranes in my workshop, and possibly two more to build. My advice is to get an engineer to design this for you. If something goes wrong with a crane the result is usually bad. In my view it is not worth the risk of personal injury or damage to equipment versus the dollars I might save by doing the job myself versus paying an engineeer.
To me, none of the pictures contain anywhere near enough useable engineering data. I realise a couple of them are concepts.
An alternative might be to look around for a second hand crane that suits your purposes?
Cheers

Hi and welcome to the Forum, Athos
As The beryl Bloke said get advice from an engineer. Even though it's in your work space, if someone was to enter it and get injured, your insurance company possibly wouldn't pay damages to the injured party, leaving you to pay, what could possibly be several million Euros!!
Even if you ban people coming in there, what happens if you sell it and the next person gets injured, you are still liable!!
NO ONE on here will say go a head and make it, as it would then leave them liable.
I found this on our Ebay in Australia, you could possibly find something similar in your country?

Hope this helps,

grazie per i preziosi suggerimenti, in realtà la gru serve come dispositivo di sollevamento per il servizio, o quando è necessario sollevare lo scarico di oggetti pesanti su veicoli o mezzi di trasporto, se si scattano foto con disegni di progetti, magari per farsi un'idea, forse se io trova sul mercato una gru a cavalletto o una gru a bandiera o altro dispositivo adatto alle mie esigenze grazie ancora per avermi accolto tra di voi grazie

Does anyone do anything without having first made sure that someone else can be blamed if it fails.
Nothing would ever be made or even designed .
When I sell my equipment if ever all lifting gear will be cut up so no demented fool can ever try to make life hard for me or others,
That includes the forklifts and cranes. They will be cut up with a plasma to render them useless.
There is way too much nanny state crap brought about by insurance companies and the "what if "brigade.

Athos,
Please appreciate that any comments made here in our Metalwork Forum are generated by the very best of intentions.
Everybody would hope that whatever you decide works out the best for you. The last thing any of us would want is to learn of an accident.
While lifting apparatus designs are pretty constant, the manufacture, the standards and quality of manufacture can vary greatly from country to country.
We can only advise based on what our own experiences have been and our own knowledge.We have no idea of what legislation and regulations of your country apply to lifting equipment.
Contributors can be therefore cautious in about what they will say in a public forum such as this, in safety matters, particularly areas where people risk being injured severely due a failure of equipment which they themselves, may have advised on.

thanks for the valuable suggestions, in reality the crane serves as a lifting device for the service, or when it is necessary to lift the discharge of heavy objects on vehicles or means of transport, if you take pictures with drawings of projects, maybe to get a idea, maybe if I find on the market a gantry crane or a jib crane or other device suitable for my needs thanks again for welcoming me among you thanks

Agreed, Michael
I too have in the past made lifting attachments for lightweight lifts up to a ton.Made for my own personal use only, they affect no one else but me if there is a failure. I have the knowledge and experience to be able do this.
I believe a lot of the bureaucratic overkill we see is brought about because those people who don't know what they are doing and don't actually recognise they are the ones who don't know what they are doing. "Hold my beer and watch this"
Our members who frequent the trailer section will already have a grasp of this notion. They will, of course, have made searches of trailer fails and welding fails . There are endless examples of those trailers ,hitch gear, etc made without the slightest knowledge or even forethought about the potential serious impact of their work upon them or others. The don't knowers seem to be a group growing exponnetially.
Hence the legislation concerning DIY trailer building in our own country was upgraded and rightly so.
It follows for electrical and other similar topics.
It is just an opinion for whatever it is worth.

grazie per i vostri messaggi e preziosi consigli, voglio sottolineare che questi dispositivi li useranno solo me sotto la mia responsabilità, quindi se collassano, sarei coinvolto in prima persona, non ho una società in cui lavorano lavoratori stranieri in caso di collasso o incidenti si verifichino incidenti o incidenti di lavoro premesso questo credo che la gru a portale sia più stabile mentre la gru a bandiera più pericolosa, poiché il carico sollecita il braccio a sbalzo come in una struttura a sbalzo, sono attrezzato per costruirli saldatore e altri strumenti, per costruire gru a bandiera avrei bisogno di un tornitore per costruire le cerniere della cerniera, il perno può recuperare da un grosso bullone, se non chiedo troppo, potresti attaccare le foto delle tue gru, solo per rendermene conto, grazie tu di nuovo il tuo prezioso intervento farò certamente tesoro di saluti athos

Translation
thanks for your messages and valuable advice, I want to emphasize that these devices will use them only me under my responsibility, so if they collapse, I would be involved in the first person, I do not have a company where foreign workers work in case of collapse or accidents occur accidents or accidents of work premise this I believe that the gantry crane is more stable while the most dangerous jib crane, since the load stresses the cantilever arm as in a cantilevered structure, are equipped to build them welder and other tools, to build jib crane I would need a turner to build the hinges of the hinge, the pin can recover from a large bolt, if I do not ask too much, you could attack (attach?) the photos of your crane, just to realize it, thank you again your precious intervention I will certainly treasure athos greetings.

Hi Athos,
Given a choice I would favour the first type of crane you showed.
poloportalovy_jerab_gpmj_3.jpg
It could cover more of the work area than the other pivot types.Certainly, it is more costly and does pose more a more difficult task of building it, but it could allow an endless chain to be used to provide a horizontal motion,something,the others, cannot offer.
If single handed unloading from trucks I think it is most stable. The dimensions of the beams you seem to have already obtained from tables. If your fabrication and welding skills are good there is no reason you should not be able to build it yourself, bearing in mind the comments made above.
As an apprentice I used one of these moving gantries that could lift a ton without problems., I don't have any pictures to attach but other members may have. Please keep us up to date when you have something to show us.
Regards
Grahame

thanks for your messages and valuable advice, sorry if I took advantage of your patience, returning to my discussion I would add at the end of the cantilever beam a tubular pillar with wheels to unload the load and weight of the cantilever type shelf structure, but I have to size everything or make a mix jib crane gantry crane hoyst, if you have other solutions I invite you to submit them to me thanks again sorry for the trouble I have caused you, thanks for your precious time

Grahame,
I also know how to , but as you said the exponentially growing group of Youtube watchers who will build something and have the " dont need all that " attitude is the problem .
It makes it difficult for anyone who overengineers even to make simple supports for equipment .

athos
Welcome and I hope that your project does what you need .
There are quite a lot of designs available , I would speak to people who use which ever one you decide to make .
That is one way to get some ideas which could improve on commercially available units.
Good luck.
Michael
