The last blogpost I made was about the Doosan CL. Now I am making a new post on the CX. I am surprised to be able to get it this quick. The Doosan CL and CX concepts are ideas of the Doosan company how construction equipment could look in the year 2020 (and money is no object, presumably). Both have interesting features like counterweights that move, to adapt for the added weight when excavating, head-up displays, independant suspension for more drive comfort and such.
