Loader development trend of domestic wheel loaders
Domestic wheel loaders are moving from low level, low quality and low price to high level, high quality, medium price and economical and practical. From imitation imitation transition to independent development, the major manufacturers continue to carry out technical inputs, using different technologies, key components and system innovation in technology, get rid of the same product design at present situation, without their own characteristics and advantages, from the strange circle of talent shows itself disorderly competition in the low level, become a leader in the loader industry.
(1) large and small wheel loaders have been limited by objective conditions and total market demand in recent years. The most competitive middle loader will be updated more and more quickly.
(2) according to the actual situation of the manufacturers, redesign the overall design, optimize the performance indexes, strengthen the strength and stiffness of the structural parts, and improve the reliability of the whole structure greatly.
(3) refine the system structure. For example, the vibration reduction and heat dissipation of the power system, the structural optimization of the system, the optimization of the performance index of the working equipment and the dust control of the joint points, and the design of the industrial model, etc..
(4) using electronic technology and load sensing technology to realize automatic shift of gear box and application of hydraulic variable system, improve efficiency, save energy, and reduce operation cost of loader.
(5) improve safety and comfort. The cab has the function of FOPS&ROPS gradually, and the driving environment will be close to the direction of the car. The steering wheel, seat and handle can be adjusted so that the operator can work in the best position.
(6) reduce noise and emission, and strengthen environmental protection targets. With the increasing awareness of environmental protection, reduce noise and emissions of the loader work has been imminent, now many big city has been making noise and emission standards for motor vehicles, construction machinery to meet emissions standards, will be limited in the area of sales.
(7) extensive use of new materials, new processes, new technologies, especially the integration of machine, electricity and liquid, to improve the life and reliability of products.
(8) maximally simplify maintenance to minimize the number of maintenance and maintenance time, increase maintenance space, electronic surveillance and monitoring technology is widely used, to further improve the fault diagnosis system, provide the driver method to eliminate problems
