Groundbreaking use of the new operating principle of transformation to a bucket, can loosen the soil excavation for the high-intensit

14、y rock, Under normal circumstances can reduce the unit cost of earthwork and improve production efficiency, and the soil near the building when substitute bored-blasting method. Vibratory Roller is a mechanical vibration and have reached a "sluggish vibration to" operational effectiveness

15、of the most powerful note. High-frequency vibration compaction technology is the application of modern dynamics in the mechanical engineering important research results, In vibratory roller simultaneously with the application of vibration isolation theory. 90s of the 20th century, there have been a

16、level of vibration (vibration) and vertical vibration directional vibration compaction method, and an AM-vibration and different from the harmonic vibration of chaotic vibration vibratory compaction operating principle, and the formation of the corresponding series of vibratory roller. Impact Roller

17、 broke the existing traditional cylindrical roller structure, Use 3-5 edge with the pressure roller polygon dragged by a tractor, 2-3 times per second in order to impact on the ground. This has dramatic impact on the seismic wave propagation characteristics, the depth of compaction several times wit

Fung plate diesel, liquefied petroleum gas or electric heating and 60 Hz frequency of vibration, and using infrared, ultrasonic or laser leveling, is a multidisciplinary high-tech applications. This leveling the technology can be applied to the ground p

20、lane, as amlodipine or fine leveling the slope. Transfer frequency mechanical vibration is also commonly used for drilling, stone crushing and sieving and Shen pulling piling works. The stone drying can use diesel, fuel oil and coal combustion of various fuels on the asphalt from the barrel, heating

21、 and asphalt mixture, stirring and insulation process is the full use of thermal theory of physics. Asphalt emulsion and some are modified chemical reaction physical specific application. 2、drive innovation : universal hydraulic and electric drive Hydraulic drive in the 20th century, the 1960s appli

22、ed to the roller, only 10 years on the time has been spread and popularize. Now roller travel, vibration, steering and braking systems has achieved the full hydraulic drive. Hydraulic drive greatly simplified the roller drive and control system design, hydraulic drive a smooth, convenient manipulati

23、on effort, easy to achieve variable speed and automation, in general, improve the production efficiency of roller compaction and quality. Now foreign markets have seen very little mechanical transmission of the roller.Hydrostatic drive technology in the 1970s began to use bulldozers, and will soon b

24、e extended to a number of small and medium bulldozers and loaders, the United States John Deere, Caterpillar, Germany Bohai benefit companies and Dole produced by Komatsu of Japan has production and sales pushed Temple hydraulic machines and loaders. Hydrostatic drive not to use hydraulic torque con

German company Deutsch

26、e mark and Lee Bohai Fall of other public companies in 1954 and in 1955 took the lead in developing a hydraulic excavator , but the hydrostatic transmission in large excavator is the popularization and application of the 1970s. Since the early 1980s, excavators and subdivided, is gradually realized

27、- powered, rotary and the hydraulic excavator of. In the international market excavators, were all eliminated various mechanical drive. Late history of the birth of the road is more mechanical hydraulic drive-based, such as paver, soil stabilizer, Pavement milling machine, hydraulic transmission smo

Drilling in the car and drilling machines, hydraulic transmission has replaced the previous aerodynamic, Wheeled modern cranes and machinery also piling work to the whole in the direction of hydraulic development. Electricity in industrial product

29、ion while the application has a long history, but in mobile machinery is seldom used. This is because, firstly, to the motor capacity of, a motor with the same power as compared to the hydraulic motor, its weight and bulk to good times, to the machinery space layout brought great difficulties. In ad

30、dition, the efficiency of electrical transmission over low efficiency and consumption of a large volume of non-ferrous metals. But electric drive can be well realized variable speed, braking and electrical power streaming - Drive more convenient and easy to large tub, large excavator and large loade
