construction driller model 3D model

The construction drilling rig is one of the models of machines that I had the pleasure to make from scratch. The contract came unexpectedly and was successful. At that time, as I remember, I made a few models of construction drilling rigs, but this one has remained with me after the project and this is what I want to share with you now.

When creating this model, I followed other self-propelled machines, mainly excavators, but from what I have figured out, this is the basis they actually have.
