Fast 7DS180 transmissions tailored specifically for mining vehicles rely on the characteristics of strong bearing capacity, high reliability, low failure rate, and flexible and convenient matching, fully satisfying the needs of special users such as mining vehicles and winning widespread praise in the market.

It is understood that the 7DS180 transmission adopts a single-cassette double countershaft structure and inherits all the advantages of the dual countershaft technology platform. With no auxiliary box, the operation is simpler and the reliability is higher; the gears and shafts have been enhanced and the low-grade area has been designed. The speed difference is small and the condition adaptability is stronger; the external lubrication cooling oil pump is more convenient for maintenance; the anti-off gear design adopted can adapt to various bumpy roads. The transmission also has many features such as flexible matching and leading advantages.

“This is a large-torque transmission product designed for wide-body mining dump trucks,” said Yang Dong, director of product application technology at Fast Design Institute. Many high-speed transmissions are used due to the special nature of mining vehicles. It is difficult to achieve the best matching scheme for mining vehicles. Facing user voices and market demands, Fast Technologies team designed and developed 7DS180 high-torque transmission products with completely independent intellectual property rights and input torque of 1800Nm by visiting users, field research, strict theoretical argumentation, and arduous technical research.

The 7DS180 transmission has undergone bench tests such as temperature rise, fatigue life, static torsional strength, efficiency, cleanliness, and tightness, as well as user road tests. The bearing capacity has obvious technical advantages over other transmissions on the market, and is particularly suitable for Industrial and mining vehicles, and began mass production in July 2012, specifically matched with wide-body mining dump trucks with heavy loads. Now we have a number of vehicle manufacturers including Tongli Heavy Industry, Yangzhou Shengda, Shaanxi Auto, Shiyan Ikeda, and Hualing.

The relevant technical personnel of Shaanxi Tongli Heavy Industry Co., Ltd. stated that using the Fast 7DS180 transmission for two years, the effect was very good and the market evaluation was also high. The 7DS180 has a simple structure and the main components are reinforced. It has high reliability and large bearing capacity. Under this special working condition and road condition in the mining area, compared to other transmissions with the same torque section and sub-tank, the transmission is faulty. The rate is greatly reduced. At the same time, due to its own forced lubrication system, it further increases the service life of the transmission and the attendance rate of the vehicle, creating additional value for the user, and has become the standard for our wide body mining dump trucks.

The 7DS180 transmission also won the favor of mine car users in many mines in Ningxia, Inner Mongolia and Yunnan. In the Ustu mining area, Dong Zhiliang, a transportation specialist, purchased 12 Asphalt 7D wide-body mining dump trucks equipped with the 7DS180 transmission assembly in April 2013. Dong Zhiliang said: “I am very satisfied with Fast's products. Their 7DS180 transmission is light, with high attendance, low failure rate, stable performance, reliable and durable, no gear change, and the timely arrival of services fully meets our needs. Safety car production, cost reduction, efficiency improvement, etc.
