At present, our business focus on energy saving loader to start a new round of technological upgrading of products, focusing on upgrading core systems and components, namely, technology upgrades and hydraulic components of hydraulic systems, transmission and drive components. It is worth mentioning that, with the domestic construction machinery products before the technology roadmap, the technical upgrading of China's loader industry has evolved from the simple to follow, follow the example of foreign advanced technology, and gradually transformed into the world's leading technology infrastructure, through technical innovation and further development the most suitable for the Chinese market loader.

         Integration of the hydraulic system changed and unchanged
         At present, the international advanced hydraulic system loader is a full variable load sensing hydraulic system, the main components, the work load sensing steering pumps are variable displacement pumps, valves for load sensing steering and load-sensing valve multi-way valve. Prominent feature of the system is operating comfort is good, high efficiency, energy-saving effect is remarkable, but the high cost, except for a few special products, in China and around the world all the less developed countries have basically no or only a small market share. To this end, China's loader industry insiders and related to the system a lot of technological innovation, while maintaining its advanced nature, scale to reduce manufacturing costs. Currently, the development and improvement of work has been achieved considerable success, mainly for the following several different structural types.
 
         Improved multi-valve is fully variable load sensing hydraulic system
         The system is still full variable load sensing hydraulic system, its innovations focused on multi-way valve. Multi-way valve body for low-cost general multi-way valve, simply add a little logic valve structure, both cost less than the sum of multiple load sensing valve quarter. Performance of the system-wide variables and the prevalence of foreign load-sensing hydraulic system rather, the total cost is only about 70%.
 
         Unloading the confluence of a given variable hydraulic system
         Unloading the confluence of a given variable steering hydraulic system is still part of the variable load sensing steering pump and load sensing valve, the working parts of the pump and by the quantitative composition of the general multi-way valve system in the addition of priority valves, shuttle valves, control valves and unloading valves, completed the load-sensing variable displacement pump with constant dosing pumps confluence realized as load-sensing steering system variables constant, while working as a constant variable system of two systems model. When the job up to the maximum load, unloading valves up to a maximum set pressure when the pump is in full working quantitative unloading state. The system solves the overflow losses throttle and steering system overflow losses, as well as operation of the system, to achieve the purpose of energy saving.
         Compared with the full variable load sensing hydraulic system, operate the system comfort, operational efficiency and its pretty basic, but the cost is only about 35% of the former, energy savings of around 70% of the former. Compared with the full dosing systems, the system energy above about 70%, the cost is about 1.5 times. We can say that a given variable confluence unloading hydraulic system is a very high cost of the system, there is some promotional value.
 
         Improved multi-way valve confluence given variable hydraulic system
         This system is basically the first two improved integrated system, steering part load sensing variable displacement pump + load-sensing steering valve, the working part of both integrated - multi-way valve by ordinary multi-valve and valve consisting of a small logic work by dosing pumps and pump unloading valve composed by priority valve to achieve double pump confluence, the basic work to achieve, both load-sensing variable steering system. Compared with the full variable load sensing hydraulic system that operator comfort and operational efficiency and of roughly equal, but the cost is only about 50% of the former; compared to full quantitative system that significant energy savings, cost about about two times the former. It can be said that the system is an affordable, high cost of a good system, a high promotional value.
