In the fourth quarter, the weather in the north turned cold, many construction projects stopped, and the demand for dump trucks decreased. For construction vehicles, production and sales turned into a low season. However, under the direction of Executive Deputy General Manager Chen Xiancai, Tianjin Xingma Technical Department has to base itself on dump trucks , conduct market research in the off-season, summarize experiences, and do a good job of product research and development to lay a solid foundation for the next year's development. After visiting the survey, it was found that the user's lifting requirements for the top dump truck varied greatly. The maximum angle of pulling mud was 55 degrees, and the sand stone was only 42 degrees. The control is between 49 and 52 degrees, which cannot meet the needs of the special users. After the user picks up the products, it is not only a kind of activity. At this time, it is impossible to adjust the lift angle. Because the lifting angle of the top dump is currently controlled by the maximum stroke of the cylinder, it means that the cylinders with different strokes must be ordered at different angles. The length of the dump truck is generally from 4.2 to 5.6 meters, and at least 4 must be prepared. A variety of stroke specifications can meet the needs of the fuel tank, giving users a lot of trouble in the use of materials, procurement, production organization and after-sales service. The front top dump truck currently uses the gas-control limit method to perform lift angle control. The entire system is mature and reliable. Can it refer to the system at the top of the front and develop a mid-top air control limit system? Although the technical staff of Tianjin Technology Department are all involved in working for a short period of time and are not studying hydraulic pressure, they are not afraid of difficulties, and they firmly follow the requirements of what they learn, start with the entire hydraulic principle, and compare the entire hydraulic circuit and control system. , I think it is more feasible, for the sake of security, also consulted the oil tank factory, air control valve factory, also make full use of the network, into the hydraulic forum, consulted the online hydraulic system experts, the entire program was optimized. Before the development of the product, there were certain risks. However, Mr. Chen indicated after he read the plan. First, he must dare to innovate. Second, he must be prepared fully. Third, he must firmly support it. Through prototype car trials, the automatic control system achieved success at one time. The first product was sent to Datong Lusheng distributors in Shanxi province and quickly received approval from Shanxi Hualing sales manager and users. Since its successful development in early October, it has so far received a total of 20 mid-top car orders from Shanxi. Through service tracking, the system is stable and reliable.
