My homebuilt Loader 3B

[Graydin]

I increased the rear side walls. This is not just for show: I need weight and space where I can place the oil tank and fuel tank. Shifting the oil tank back will allow for lifting more cargo. At the same time, the overall width of the loader will remain unchanged, which will allow it to enter narrow gates and doors. Sometimes, even into a house, since the loader will be no wider than 1200mm. These are still just drafts and sketches. It is possible that I will make changes during the design process. Errors in design are not acceptable. The result will be determined by calculations, tests, and loads.

Welding the front part from all sides

Here you can see how I prepare the joint node of two semi-frames. The front and rear parts.

Front part. The hydraulic rotation cylinder will be mounted here.

Rear part. Here the rotation hydraulic cylinder will also be mounted.

A very important element is the pivot nodes. I take a steel rod. First, I drill a hole, then I enlarge it on a lathe with a cutter, and then I finish it to high precision with a reamer. And into the resulting sleeve, I press in a bronze insert with a Teflon coating. This is a maintenance-free bearing that does not require frequent lubrication. Quite reliable and undemanding. Just what is needed on a remote ranch. the bushing fits very tightly on the rod. Without lubrication, I have to exert effort to move the bushing along the rod

I'm sorry that you can't see the video. I don't know where I can upload the video so that everyone can see it. Maybe you can suggest something to me?

I have moved on to an important step - the lifting boom. I am starting to fit and weld the guide bushings.
