China Construction machinery information

Guide: entering the cost quarter of four charged parts, the weather in the North turned cold, many construction projects stopped, the demand for dump trucks decreased, and the production and sales of engineering vehicles turned into the off-season. However, under the instruction of Chen Xiancai, the executive deputy general manager of Tianjin Xingma Technology Department, we should base ourselves on dump trucks and conduct market research in the off-season, which represents the experience of exposure to particles, moisture, sweat or other pollutants in use

in the fourth quarter, the weather in the North turned cold, many construction projects stopped, the demand for dump trucks decreased, and the production and sales of engineering vehicles turned into the off-season. However, under the instruction of Chen Xiancai, the executive vice president of Tianjin Xingma technology department at the annual meeting of China Scientific Instruments (accsi2013), we should base ourselves on dump trucks, conduct market research in the off-season, summarize experience, do a good job in product research and development, and lay a good foundation for the development of the next year

through the interview and research, it is found that the lifting requirements of users for the middle roof dump truck vary greatly. The maximum angle of pulling soil is 55 degrees, and that of pulling sand stone is only 42 degrees. Most of the middle roof trucks made for users in the early stage are controlled between 49 and 52 degrees, which can not meet the needs of special users. After users receive the products, they do not just pull 'tape' to 'tear' a single layer of graphite from the graphite surface - graphene is a kind of live, At this time, it is impossible to adjust the lifting angle adaptively. At present, the lifting angle of the middle roof dump depends on the maximum stroke of the oil cylinder, which means that oil cylinders with different strokes must be ordered from different angles. The length of the cargo compartment of the dump truck is generally from 4.2 to 5.6 meters. At least four kinds of oil cylinders with different stroke specifications need to be prepared to meet the needs, which brings a lot of trouble to users' use, material procurement, production organization and after-sales service

at present, the front roof dump truck adopts the pneumatic limit method to control the lifting angle. The whole system is mature and reliable. Can we develop the pneumatic limit system of the middle roof with reference to the system of the front roof? Although the staff of Tianjin Technology Department didn't work for a long time and didn't learn hydraulic pressure, they were not afraid of difficulties. They resolutely followed the requirements of what to do and what to learn. Starting from the whole hydraulic principle, they compared and analyzed the whole hydraulic circuit and control system, and found it more feasible. For the sake of safety, they also consulted the oil cylinder factory, the pneumatic valve factory, and made full use of the network to enter the hydraulic forum, Consult the hydraulic system experts on and optimize the whole scheme

before the product is developed, there are certain risks, but after reading the plan, President Chen instructed: first, dare to innovate, second, be fully prepared, and third, firmly support

through the trial production of the sample vehicle, the automatic control system has achieved success at one time. The first product was sent to Shanxi Datong Lusheng dealer, and was quickly recognized by Shanxi Valin sales manager and users. Since the success of research and development in early October, so far, it has received a total of 20 top vehicle orders in Shanxi. Through service tracking, the system is stable and reliable
