Hi All,

Can you help me out? I need an electrical diagram for an overhead gantry crane. has to be of the traditional contactor / relay control and wired pendant. North- South, East-West and Up -Down 2 speed if possible. Doesn't matter what control voltage. Its for an internal project for one of our apprentices.

Thanks

Well, the existing crane will have a User Manual and if it doesn't then a telephone call to its manufacturer will rectify the problem.

Hi. There is no existing crane. We don't have any. Its simply a university project. Otherwise I would use one I had.

Why do you want to select electrical diagram for an overhead gantry crane for your apprentices training. You can select DOL or Auto Trans Starters. It would be much easy.

Hi, I could go into details, but is part of a 3 part project. There will be mods to the basic control, but he has to start off with a basic system, and then move forward from there.

It's is sometimes best to prepare your question with some background information........ otherwise the information will get milked out of you.

Didn't think it was a complicated request really. Maybe people should read the post before answering! It don't want to use DOL, if I had a drawing, I wouldn't ask for one. Didn't want a protracted thread, just someone to answer yes or no to a simple question. Dies anyone have a drawing? Not complicated is it?

Make it a 4 part project and include the drawing as one part!

My answer is "No" I dont have a drawing! But admit it you are not doing a statistics. A yes and no answer is not what you had in mind! You still need the drawing.

Your best bet is with a gantry crane manufacturer and maybe they are willing to give you the plan.

How about going to a scrap yard and dissassemble a steering and make your own deductions/drawing?

Maybe start here.

Or why not this?

Yes or no?

That's the first thing he will do, and no, I am not doing statistics. I have been on the web for images, but to get a good quality one, they all want credit card details first, to "register me" The ones you can get are not complete, or not clear. Too time consuming going to a yard and stripping one down, especially when most factories that have cranes will have drawings. Hence, my looking at an engineering forum.

No you didn't think it'll be complicated, one thing this is a blog site composed of engineers. Great resource, yes.

The prime objective of an engineer is safety.

You'd would be surprised the intentions of a new member would try, and as an engineer it is our duty to get details so you dont hurt yourself....... no matter what your confidence is, or worse yet, hurt someone else.

But, if its a simple answer you seek than, No.

No it's not complicated. Any yes a great resource. Now just to set the record straight, I am an engineer. I have an MSc in advanced manufacturing and robotics, and I am very aware of the safety aspect. But your simple answer of no, is fine. You see, two weeks ago, on another forum, a chap asked for some help. He wanted a cad drawing of an AJ 27 camshaft in solid works. I could and did help him. I didn't ask him to change to another camshaft, or change to a different cad type. I assumes the chap knows what he wants, so I helped. My answer was simple. "Yes mate, no problem" and sent him the file. Now that is helping others I think.

Ah, thanks. That will be a start for him. I did find the other links but, they ask for card details etc. Don't mind paying, if its genuine, but you never know. Thanks for your help though.

You could do your own drawings and homework.

You say a three movement, two speed machine? Not very difficult for an engineer of your vast experience.

Goodness me! Read again. It's not my homework, and we could probably sit down and do some drawings, but i have a production facility to run. but more importantly, That would defeat the whole project he has set himself. And the last comment? Boring.

Sir:

I have no intentions of have any of my remarks being taken as directed negatively towards you. Please do not take these as comments about you or any of your endeavors. I have an old retired engineer's body but my mind can't accept the body age. I have a few hints I would like to share with you.

Keep the negativity towards someone under your breath. You never know when it will choke you. As many other posters have seen and have heard me complain about, don't attack or present anything other than positive comments to others. You never know when someone who might have the answer to your question will not give it to you, but give you a spiteful comment or answer because of something you have done in the past that you don't ever recall what it was. It also includes what they have seen you do to others.

This is an open forum. Anyone can give an answer. It is up to you to dig through the answers to find the correct one, not the posters responsibility. What they post can be real good and it also can be trash. Some people will purposely give bad answers that most would perceive as good simply because "they feel like it".

You have very impressive educational credential and express that you have much vocational responsibilities. Work on improving them. From my view, as I sit at my keyboard on a Saturday night, you might want to improve on your non technical skills, such as supervision, human resources, dealing with people, working with non technical personnel, etc. Just my interpretation of your postings, but take it for what it is worth. Hey also, how do I know that what you state you have is really what you have? I only really know by what you post.

Learn from others so treat them good. How do you know that I am retired and loving it? How do you know what my career was so you know how smart I am about a subject. You don't know my education. You don't know my hobbies. You don't know if I am full of B.S. or have real smarts? It is up to you to make it clear what you want and need your question for. The better your question is the better the answer is. In my day it was: GIGO-Garbage In, Garbage Out! This is from a guy who learned on an IBM 1130. 64KB memory, 1mb removable disk (the first one made) and 80 column cards. A LEGO toy probably has more than that!

Most of my career was spent as the "go to guy". I had to fix and get running the things that came out of the "shiny pants engineers", who sometimes really screwed things up. I did a lot of design work but most of it was on my feet.

Can you believe all this? You can't. It could all be true or it could all be lies and B.S. Don't ever get negative to anyone you work with, next year they could be your boss. Sometime, I hope not for you, you will get the same that you gave thrown back to you!

I hope this little (or long) list does not upset you. I give it to possibly help you.

Lastly, if this project for the intern or whatever he is to show him what engineering is about, HAVE HIM DO THE SEARCHING and find the source of the diagram and obtaining one. It will be invaluable learning for him. A lot of engineering is that sort of thing.

Good Luck, Old Salt

Hi Old Salt,

Thanks for the reply, I appreciated it! I accept your comments genuinely. I have the utmost respect for the real fixers as you say. Without them, the manufacturing facilities would stop dead. I have 160 people working for me, and I take my relationship with them very seriously. Indeed, I am very fair and obliging actually. But I could just be saying that, your correct there too! My point was simple really, until I received, as you say some spiteful comments. Cant abide people like that. Then I just fired a few back. Anyway, as for my intern, he is a good chap, and he is up to his head with work at the moment, so I thought I would assist him. He is very capable of searching himself of course. He already has a BSc in Metallurgy. My thought was to try and help him by acquiring or even purchasing a set of older drawings while he is away working for me.

Thanks again!

Over head cranes have many benefits but the common one which every cranes posses that are for lifting and shifting of heavy loads. Some of the company also provides custom electric panel to desired instructions of clients. They also provides lots more features related to cranes, they are as follow:-
apacities up to 500,000 kg
hoisting speeds up to 120 m/min
duty cycle to fem 5m
hazardous location rated available

available for use in extreme environments
