Having worked on construction sites, i wondered then and still wonder now why the pumper trucks are called "concrete pumpers" and not "cement pumpers"? Cement dries to become concrete, which is hard and hardly pump-able. Concrete is still a concrete even if it hasn't hardened yet and is sitting in a mixer truck or pumped through a line. Cement is just one of the components of a concrete mixture. In 1985 at Peabody coal mine, kayanta Az black mesa mine. I was at tire shop about a scraper tire. Radios said a loader was bringing in a sick D9. Thought I got to see this. A Dart loader rolled up to mechanic shop, with a full dress D9 in the bucket. With U blade and 3 bar ripper. Unless kumatsu can do the same it’s not the biggest. At 3:15 you state that it generates 2300 HP but not the torque the 2300 HP means almost nothing for this engine because even a boosted 2JZ engine can produce 2300 HP but its not going to be able to move this machine when talking about Diesel engines can you include the Torque?
