Discussion Overview

The discussion revolves around seeking a sample project for a truck-mounted crane, including drawings and calculations. Participants explore various aspects of crane design, lifting capacities, and the complexities involved in creating such a project, particularly focusing on hydraulic components and safety considerations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant requests a sample project for a truck-mounted crane, expressing a need for drawings and calculations.
  • Another participant inquires about the specifics of the project, including the type of lift and the design requirements for the crane.
  • A participant mentions concerns about hydraulic components and the complexity of the design process.
  • There is discussion about the lifting capacity of the crane, with some participants clarifying that the truck's carrying capacity is 15 tonnes, while the crane's lifting capacity may be lower.
  • Concerns are raised about the feasibility and safety of designing a crane from scratch, emphasizing the need for knowledge and experience in crane design and operation.
  • Some participants suggest that it may be more practical to purchase a professionally designed crane rather than attempting to design one independently.
  • One participant notes the importance of understanding applicable standards and codes for crane design and operation.

Areas of Agreement / Disagreement

Participants express a range of views on the feasibility of designing a truck-mounted crane from scratch. While some caution against the risks and complexities involved, others see it as a potential design project. There is no consensus on whether the original poster should pursue designing their own crane or opt for purchasing one.

Contextual Notes

Participants highlight the need for extensive knowledge and experience in crane design, as well as the importance of adhering to safety standards and regulations. The discussion reflects uncertainty regarding the specific requirements and challenges of the project.

Who May Find This Useful

This discussion may be useful for individuals interested in engineering design, particularly in the field of mobile cranes, as well as those considering projects involving heavy lifting equipment.

hello guys,
Do you have any sample project of Truck-mounted crane that contains drawing,calculations ?

Best Regards

Welcome to the forum...

I'm curious what you need these for. Care to elaborate on the project?
 
thank you :)

Actually, i just think that lifting 15 tones.I didn't think other details.If I could one project to examine ,it would be helpful to specify other properties.Especially i am worry about hydraulic components and design,i think it is going to be very complicated :(
 
I can't be of help in your quest, but I do have a couple of questions that might make it easier for others to do so.
Is this a straight lift, as a tow truck would perform, or do you have to shift the load laterally as well? How long does the boom have to be, since that has the most serious impact upon the mounting plates and outrigger design? When you say "hydraulic crane", do you mean that you want to have everything accomplished with cylinders? I ask because a winch driven by a hydraulic motor would qualify under the same definition.
 
You asked good questions but before i said,I can just specify value of lifting because i have no idea this kind of cranes.When i saw the this truck-mounted crane,i think to search about it.But i couldn't find any source,document etc... .I have just found companies that was manufactured these cranes :) .So,i think someone can help me ...

In that case, how about if you tell us, to the best of your recollection, what this crane was like?
Let's start with the truck. Since you specified 15 tonnes, I figure that it has to be a dedicated drivable crane as opposed to a truck with a crane attached. (I very well might be wrong about that, but I personally have never seen an on-deck truck crane that could handle more than about 5 tonnes.) So, did it happen to have 2 dually axles on the back and 1 mono steering axle up front, with tires about 1 metre in diameter? If so, it was a mobile crane as opposed to a truck.
Now, describe the boom as best you can. How many segments? Cable for the last stage, or a hook directly attached to the last segment?
Anything else that you can think of to describe it will help. I have a suggestion in that regard. Google "mobile cranes" and go to "images". If you see something that looks like what you want to know about, click on it and then capture the image. Post it, or a link to it, here and then we'll know exactly what you mean.
 
like that

Okay, then. Good job.
I must say that I'm very surprised by the size of those things. They look like the ones that I mentioned as handling 5 tonnes maximum. Are you sure about your numbers?
I'm also a bit puzzled by the final picture, because of the angle and cropping. Is the cab articulated on that vehicle, or is that a second steering axle under the boom?
Actually, maybe we should establish whether or not we're using the same terminology. When I mention the crane capacity, which you put at 15 tonnes, I mean how much it can pick up and manipulate in one go. If you happen to mean the carrying capacity of the truck, that's different.
 
Oh no :),i want to describe this truck that carrying capacity is 15 tonnes .Yes, as you said,it could be 5 tonnes maximum.

Whew! That's a relief.
Alright then. The truck can be just an off-the-shelf flatbed that you can get at any dealership. Since you asked about formulae, might I infer that you want to build your own crane onto it? (I can say with reasonable assurance that it will be a lot simpler and cheaper to have one professionally installed. If you do it yourself, the insurance premiums alone will probably kill you.)

Yes, you understand it.I want to design my own crane.So,you think this project is a kind of
R & D.We know this is our first design in this situation.Our first purpose is designing this machine.

No one is going to make the design of their crane public because then anyone can build it.

You're going to have to design your own from scratch unfortunately.

To which I'll add: either be prepared to spend loads and loads of money on design, testing, manufacturing, certification, etc., or do not proceed. Lifting heavy loads (like 15 tons) is dangerous and can yield catastrophic results if not done properly. This is especially true for mobile equipment.

Either fork up the money to design the thing properly, or just bite the bullet and buy one (note: there is a reason why most people who buy cranes, buy them as opposed to designing them from scratch.

I'd hate to discourage you from doing something potentially rewarding (both personally and professionally) but given that you don't sound like you know much about mobile cranes in general, I feel I should caution you as designing mobile cranes requires heaps and heaps of knowledge and experience.

Good luck with whatever you choose to do.

This would be a fun design project, and fairly simple for an engineer familiar with noble cranes. What is not so simple for someone not familiar with them is to figure out which standards and codes apply in your jurisdiction, and then performing the required tests and certifications that you meet them.

I tend to agree with this. If you're not familiar with the design, operation, and certification of a crane (especially one lifting 15 tons) you're better off finding someone that builds cranes and buy it from them.
