This series is about the SDM 25 motor grader, which is manufactured by the Spetsdormash Chelyabinsk enterprise. You may have already seen a review of the DZ 98 heavy grader on the Konstantin PRO channel. It turns out that the SDM 25 grader is very similar to the DZ-98 heavy motor grader, and the tasks of this special equipment are the same - road construction work, grading and leveling of roads. Of the external differences, the SDM 25 grader, unlike the DZ-98, has a rectangular cross-section frame, if you remember, UMG group road construction equipment is made using a round pipe. But these are all external signs that do not greatly distinguish these road construction machines. More obvious differences are associated with the transmission. The Spetsdormash plant from Chelyabinsk uses gearboxes and axles from the Kirovets K-700 tractor in the design of its new grader, while ChSDM produces transmission units independently. Special equipment has the same YaMZ-238M2 engines, but as I understand it, you can buy a SDM 25 motor grader with a YaMZ 536 engine and, what is important, with an automatic transmission. The most important difference between these two motor graders is that the SDM-25 is heavier than the DZ-98, which in turn affects the pushing force, see the video review for more details. The review of special equipment ends with a visit to the enterprise's workshops. You will be able to see how it is done, from cutting metal to assembling finished road equipment. Road construction equipment is quite in demand. Our country is large, and accordingly we need more roads. Today, Spetsdormash produces 3-4 graders per month, while its neighbors manufacture 15-17. I hope that the production of special equipment at Chelyabinsk Spetsdormash in particular, and mechanical engineering in Russia in general, will develop. The quality and comfort of products will grow along with production volumes. When there are people "sick" in a good sense of the word with the idea of reviving mechanical engineering, there is faith that not all is lost. I want to believe that the labeling made in our country, made in Russia will again acquire the meaning of high-quality, reliable, popular equipment. In recent years, the government has begun to somehow help our Russian manufacturers, I hope the trend will continue, and special equipment of Russian production will be mostly made of domestic components.
