The western part of Gansu Hexi Corridor is an important pass on the ancient Silk Road. The Dang Jinshan section of 215 National Highway across the region is considered as one of the national top ten dangerous roads due to its steep slopes, sharp turnings, rugged paths, and frequently occurred major pernicious accidents which have long been daunting to many users. Since this year, Fast hydraulic retarders have been applied in the vehicles in this region, where the largest local professional transport tippers for Dang Jinshan limestone mining have all used Fast hydraulic retarders and 10-gear large center distance transmissions, gaining good reputation among customers.
"This year, over dozens of Shaanqi state IV heavy trucks equipped with Fast parallel retarders have been put into use in limestone mining and well received by users. In view of this, we have recently also asked for another more than a dozen diesel dump trucks fitted with fast parallel retarders. "Zhan jiFei, technical director of Dunhuang Huantong Automobile Trade Co., Ltd, thinks that the dump truck with a retarder gaining instant recognition by the market is mainly because the users have been strictly pursuing the safety performance of heavy trucks and highly trust the reliable braking performance of Fast retarders.
