My homebuilt Loader 3B

[Graydin]

Greetings everyone! I want to show you how I build my front loader. I'll start with a bit of history: The design does not belong to me. My loader will be a combination of a general design idea that has been working for a long time and has proven to be reliable and well thought out, along with my personal modifications that I hope will make my loader even more convenient and reliable. The main goal is simplicity, affordability, easy and cheap repairs, and convenience when working with it.

"Here you can see how the idea originated and what it has turned into today. There is such a machine in the family. This is where my loader was born."

As a result, one of my compatriots assembled an intermediate version that greatly interested me. It is this version that you will see in the photographs below. I bought a DIY KIT set from him. The seller did not limit my responsibility for copyright and still sells kits for free use, without restrictions. I am grateful to him for this, as it provides a basis on which I can realize my personally designed machine. And this is very valuable to me as a designer.

Now that I have the basic data, I can start developing my...

So far, it looks very similar. But I am just learning to work not on paper, as I was taught in the Soviet Union, but on a computer, in SolidWorks. It is a great program that allows you to change the sizes and shapes of parts "on the fly." It's really cool, and I enjoy learning, even though I am almost 50 years old...

Initially, I will assemble the loader, which I purchased as a kit. Following this, I will conduct testing to identify any shortcomings and develop my own version, aiming to achieve the optimal balance of price, quality, and simplicity. Subsequently, attention will turn to the caterpillar model, which I will discuss in a future thread at a later time.

Very cool; I look forward to seeing your progress- folks like you, who are smart enough to design and build machines themselves, are inspiring!

It is fun to watch your ingenuity in action. Keep sending some pics as you go along.

Thank you very much. You have no idea how important your support is to me! I spent 12 hours at the computer)))) And here is what I can show you. I could have limited myself to photos, but I thought you would be more interested to see how the boom and bucket work... There are still few of my developments here. Just the bucket. But, during the drafting process, I saw several important changes that are necessary for this design to improve its quality and simplicity. God, how interesting it is to work on this!

So, while there is an opportunity, I am starting to make changes to the design. I do not like the weak joint node between the rear and front parts of the loader. In the old version, all the load is on the bushing, which is welded with only one weld. This is unacceptable. In the case of diagonal wheel suspension, the node works on a break and deformation is possible. I removed the oil tank inside the rear part, added metal and strength. Now the lower mounting of the loader frame hinge is a solid part and not a weld, as it was before.
