Golden Century (Jiangsu) Intelligent Technology Co., Ltd. is a wholly-owned Hong Kong holding enterprise with a registered capital of 62.3507 million US dollars. Located in the eastern suburbs of the ancient city of Yangzhou, with beautiful environment and convenient transportation, adjacent to the Beijing Shanghai and Ningtong expressways. Our company specializes in producing tractor rims, large, medium, and extra large tractor rims, automotive wheel hubs, half shaft machining, as well as various precision machinery and automation equipment. Our company has the ability to design and develop various large and extra large steel rings for users. Currently, we are the only steel ring manufacturer in China that can produce the widest and largest diameter steel rings, with a complete range of varieties. Our company covers a total area of approximately 80000 square meters and has about 400 employees, including about 60 professionals in various fields. Our company has advanced equipment and strong technical strength. On October 19, 2016, Golden Century Group successfully went public on the KSDAQ market in South Korea, with the stock code 900280. In September 2019, the company established a joint venture with South Korea's Dimachi Agriculture Co., Ltd. to develop and produce the "Dimachi" tractor, the "Dimachi" brand tractor, which has now formed six major series including TS series, TC series, TDF series, TD series, TB series, TE series, and more than 20 models. The "Dimachi" series tractors cover the power range of 240Hp to 50Hp, fully meeting all agricultural operation requirements and suitable for various agronomic requirements. The differential adopts electro-hydraulic control and has three working states: automatic, closed, and forced combination. When working on farmland, the differential is in automatic engagement mode. When the front wheel deviates and turns, the differential automatically unlocks, and when driving straight, it is in engagement mode again. This function prevents relative slippage of the locomotive's rear wheels and maximizes the output of traction force. The gearbox adopts synchronizer shifting, with 16 forward gears and 16 (8) reverse gears or 12 forward gears and 12 reverse gears. The gear distribution is reasonable and the agricultural adaptability is strong. The gear shows continuous growth, enabling effective power output and meeting the speed requirements of various agricultural machinery operations. In the future, the company will focus on introducing advanced load shifting transmission systems from abroad, digesting and absorbing advanced technology, and controlling the cost-effectiveness of products to produce the "Dimachi" load shifting series tractors. This is also a project encouraged by the Chinese government, and government subsidies have clearly increased the guidance and encouragement of technology development projects. Tractors are mainly composed of diesel engines, chassis, electrical equipment, etc. The diesel engine is the power device of the tractor, and the "Dimachi" series tractors adopt non road national III engines from well-known domestic enterprises such as Shanghai Diesel Engine Co., Ltd. and Weichai Power Co., Ltd., with strong power and large torque reserves. The front axle, gearbox, rear axle, and hydraulic system adopt European manufacturing technology, with high material strength of components and large overload reserve coefficient. The bridge is equipped with a deflection angle sensor, And work in conjunction with the rear differential lock. The front axle failure rate is zero, and there are no major faults in the transmission and rear axle.
