Since 2011, in order to respond to the needs of the market, Hualing has strengthened its investment in scientific research. The latest development of mining dump trucks has been put into the market in batches, and the dump trucks of Hualing Mining have won the favor of users with high stability and high attendance.
The reason why the Valin Mine Dump Truck can be recognized by users is inseparable from its strong R&D strength. It is understood that the cab of the Hualing Mine is equipped with a self-unloading cab, adopting a full three-dimensional digital design, integrating Valin's high-end heavy truck design concept, European cutting-edge style, and a full-scale interior upgrade; the airbag full-floating seat automatically adjusts the balance point according to weight. Soft, comfortable, pre-tensioned seat belts, seat belts and seats are integrated, which greatly increases the safety factor and ensures the driver's safety; the steering wheel is adjustable up and down, suitable for different crowds; Europe is popular with integrated air conditioning systems. The cooling capacity reaches 4,500 kcal to meet the harsh working environment in the wild and the needs of demanding users. 
The cab is equipped with electric and hydraulic dual-control turning mechanism for easy maintenance. The engine uses Weichai WD12.336 diesel engine, strong and reliable, efficient fuel-efficient, low noise and environmental protection. Clutch adopts imported enhanced clutch, hydraulic control, pneumatic assistance, flexible operation, increased diameter, complete separation, strong drive. The gearbox is mainly imported from Shaanxi Fast and developed by the advanced technology of Eaton Corporation in the United States. It has a double countershaft transmission and has a large transmission torque and a wide speed ratio range. The Hualing Drive Bridge adopts special bridges for the Meishi Engineering Vehicles of Xuzhou in view of the bad road conditions in the mines. The front axle is made of high-strength welded I-beams, bold tie rods, high-strength integral cast axle housings on the rear axle, double-bridge drive, and double-stage reduction , Large speed ratio, high torque, high load, effectively reduce axle failure rate. Differences between shafts and wheel differentials improve the overall vehicle passability.
Bold thrust rod V-shaped layout, simple structure, reasonable layout, practicality; Valin balance shaft for mining road conditions, the use of high-strength steel casting, size increase, bearing increase. The plate spring seat adopts double U-bolt structure. The shaft shell adopts double oil seals to effectively improve the lubrication environment. After repeated trials by users, it reflects well. About Suspension: The front suspension of Valin uses a bidirectional hydraulic shock absorber to effectively reduce the amplitude of the front axle. After the suspension developed a reinforced multi-leaf spring, the bearing capacity of the leaf spring is greatly improved; the double U bolts are diagonally fastened, and the structure is scientific and the pulling force is enhanced. The steering system adopts the German ZF hydraulic steering gear and arranges the hydraulic pump at close distance to reduce the pressure loss. The steering pipes are all made of seamless steel tubes. The right large cylinder cylinder assists, the steering is light, the reaction is sensitive, and the turning radius is small. Improve the driver's work comfort. The brake system is a dual-line brake system that acts independently. With parking brake, service brake, emergency brake three functions. Engine exhaust brake, effectively improve the stability of the car downhill.
After several years of operation, Valin has accumulated a solid strength. The funds of Xingma Group, Hualing's leading heavy truck technology, and the quality of Xingma's special vehicles make Hualing dump trucks durable and able to create more for users. The advantages of economic benefits continue to attract users.
