The first thing that caught my attention about the PAUS Dinting Machine PSF 200, is the word “dinting” attached to its name. According to The Free Dictionary, dinting is the action of forcibly putting a dent into something. Together with the biggest mine in Russia - Norilsk Nikel - Hermann Paus Maschinenfabrik developed the PSF 200 to maintain underground supply routes.

In the past, a hydraulic hammer was used to loosen rutted road surfaces, which were then graded. This required two machines and proved inefficient. With the Paus PSF 200, the functions of “dinting” and “grading” is in one unit. Using a dinting-head made by the company Eickhoff, the Paus PSF 200 easily copes with hardened roadway surfaces up to 500 mm and rock hardness up to 80 MPA. To minimize dust, a sprinkler system is installed above the dinting-head. As the dinting machine loosens the rutted surface, a scraper blade fills in the ruts and levels the road. This sounds like a great solution and I’m surprised this isn’t a machine you’d see at all mines, whether underground or not, since I sure well-maintained roads result in optimized vehicle speed and ultimately improved productivity.
