XCMG: China's First Two-Wheel Milling Helps Xuzhou Subway Construction
In the past month, two-wheel milling machines competed with 10 hammers on the same field. As of now, a total of 15 slots were completed, of which 8 were completed with two-wheel milling. XCMG's two-wheel milling has been highly evaluated by the construction party and the metro construction contractor for its superior advantages of high efficiency and high slotting accuracy.
The research and development of the TC80 double wheel milling has successfully filled the gaps in the country's high-end basic construction machinery. It has helped China's basic engineering machinery industry into a new stage of diversification and high-end development, and has achieved a breakthrough in full-face milling. Intelligent control of rock, milling and other functions. The "climbing and milling" method with the combination of two-wheel milling and grabs is very suitable for the construction of connecting walls of urban subways, high-rise buildings and bridge anchoring ingots, because of its small disturbance to the formation, high rock breaking efficiency, high slotting accuracy, and slotting. The advantages of deeper and other equipment that are difficult to match are favored by contractors and construction parties in hard rock geological cities like Shanghai, Wuhan, Guangzhou, Shenzhen, and Hong Kong.

In short VFD, is an energy saving device by converting fixed frequency to adjustable frequency to control AC induction motor in variable speed base on the load's changes.
VFD also know as variable speed drive, frequency inverter and adjustable frequency drives. VFD also works as a phase converter to convert single phase input to three phase output in small ratings.
Frequency (or hertz) is directly related to the motor`s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor`s load. As the application`s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement.
HUAFEI company is expert VFD manufacturer in China, its VFD is mainly used for the machine in coal mine, such as the hoist, belt conveyor, ventilator, water pump etc. Explosion proof type is used under ground with combustible gas and dust. Medium Voltage VFD is mainly used for hoist ventilator or other motor with medium voltage input.
