Double Star Machinery developed a "giant" trolley

"The successful trial production of the 120-ton extra-large rotary gantry was successful!"
"Great, this equipment fills the domestic gap."
......
Recently, the largest rotary blower with the highest technological content developed by the Double Star Machinery Corporation was officially released. The device can clean extra-large cast steel and iron castings with a diameter of less than 9 meters and less than 120 tons. It can be widely used in the cleaning of heavy-duty armored vehicles in the military industry and in the machine tool industry.
Double Star Machinery Corporation dared to break through and boldly undertake difficult, high-grade orders. Double star rotary trolley shot blasting equipment, complex structure, high technical content, production difficulty, only the rotary trolley needs to carry 120 tons of large workpieces, but also the trolley will also need to rotate, such heavy equipment manufacturing There is no precedent for success in the country.
In order to overcome the technical difficulties during the installation process and ensure the success rate of equipment assembly, the Double Star Machinery Corporation established a technical research team. When assembling the vehicle body, it encountered a problem that the weight of the vehicle body exceeded the target, and the 120-ton workpiece was encountered. On the trolley, there was a phenomenon of “shaking” the trolley, which affected the quality of the product. The team "does not bow before difficulties and dare to face difficulties". After repeated argumentation, it finally used the principle of "triangle stability" to reinforce the trolley frame and completely solved this technical problem. When assembling the drive device, it was found that the output part of the gear box was not guarded. According to their own experience, they learned that as time goes by, they may invade the dust and affect the service life of the gear box. They did not stick to the requirements of the drawings, and in the output part. With a protective device, this problem has been solved.
After more than 50 days and nights of fighting, the Double Star Mechanical Commando has captured 22 technical difficulties, known as the industry's "giant," and the largest domestic rotary blast cleaning machine has finally successfully made its way off, marking the double star. The production capacity of machinery has entered the international advanced level.
