Interesting machine. Its amazing how many variations of every machine has been made in this world.

This is an interesting post and covers different types of excavators, so let's take them one at a time?

First let's discuss the most interesting design? In my opinion they are the machines like the Hydromac in your second post in this thread. It is basically a crawler dozer/loader undercarriage with a rotating upperstructure resembling a loader, but with articulated arms so it can sit in one spot to dig and load. It is in the same group as the Benati Multi Works 140 (there was also a later Multi Works 180), Tellus 125C and Bucyrus-Erie 60-S (which has a different style of undercarriage). Here's a short video of it in action:

There are also machines like the Colmas 170H which are just a crawler loaders (no articulated loader arms) with a turntable giving them the ability to rotate. There was also a red and white machine like this I have seen photos of, but I can't remember if it was from CMC or Yutani. Somewhere I have a photo, but no time to look for it right now.

Machines like Yumbo 35 and Simit SL9 are conventional hydraulic excavators in my opinion.

The articulated Mecalacs are their own breed.

For what it's worth; I'm searching for original brochures and catalogs on the Benati, Hydromac and Tellus machines for my files. Can you help me with this search?

I'm sure you have seen some interesting prototypes. There was a lot of innovative thinking and engineering in Europe in the '60s and '70s, and it is my personal opinion that more prototypes made it into the iron than here in America.

Here is a photo of the Benati Multi Works 180 I mentioned.

Bucyrus Erie made a prototype 5 yd. loading shovel that rotated but never put it into production. It had tracks more like on a tank.

I believe that these machines have been conceptual prototypes, a cross between the front loader and excavator crawler around is not found it will hidromac simit, it brunerifiat alllis or other older historic brands, you have other information to you? thanks for collaboration
