Movable Vacuum Tube Lifter which is combinated Vacuum Tube Lifter and articulation Crane fixed on a Movable chassis ,It can be Moved by manual or Automatic ,two types option . So the best advantage is that customer can put it on any place they want to use. And the Vacuum tube lifter can lifting varouis of material products, ones of bags ,cartons,bucket ,glass panels , So people also named it Bags Sucker.Cartons Sucker or Vacuum Bags Lifter ,Vacuum cartons lifter. It's not limited to these but also can suck and lift televison .computer case, handling car windscreen, especially for chipboard process loading, wood panels lifting.
So this kind of Vacuum lifter has a very wild of application ,it usually apply to food ,chemical and medical industry that stack bags cartons product from packaging conveyor line. And also appliance in hardware boxes lifting ,sanitary product Vacuum lifting ,Household appliance carton stacking , bucket handling ,Burrels lifting ect.

Next, Xiao Bian gave a brief introduction to some of the more professional terms in the digital wireless image transmission process, so that you can better understand digital wireless image transmission:
1, audio: also known as audio frequency is the frequency that human ears can hear. Usually refers to the frequency between 15 to 20000 Hz.
2. Voice frequency: Language frequency within the audio range. In the general telephone path, it usually refers to a frequency between 300-3,400 Hertz (Hz).
3, video: The frequency range that the television signal includes is from tens of Hertz to a few megahertz, video is the collective name of this frequency.
4. Radio frequency: The frequency of the electromagnetic wave that the radio transmitter can efficiently transmit to the space through the antenna, collectively referred to as radio frequency.
5. Signal: The amount of electricity used to express or carry information.
6. Channel: The path divided according to the characteristics of the transmitted information. Including paths that may be implemented but not yet implemented.
7. Carrier: A sine wave or periodic pulse that acts as an information carrier and is called a carrier (or carrier frequency). As the signal wave changes, the amplitude, frequency, or phase of the carrier wave is changed accordingly.
8. Corridor: The passband occupied by a communication device is called a channel. Usually a communication device has many channels in its frequency range.
9. Passband: The frequency range of the current that a circuit is allowed to pass through is called the passband of the circuit.
10. Cut-off frequency: When the amplitude of the input signal of the circuit is kept unchanged, the frequency of the output signal is reduced to 0.707 times the maximum value, or the frequency is called the cut-off frequency when a certain special value is specified.
11. Frequency Coverage: The frequency range in which the communication equipment operates is called frequency coverage. The ratio of the highest operating frequency to the lowest operating frequency is called the frequency coverage factor.
12. Sensitivity: The radio receiver's ability to receive weak signals is called sensitivity. If a receiver can receive very weak signals, the receiver's sensitivity is high, whereas the sensitivity is low.
13. Fidelity: The degree of similarity between the output signal of the receiver and the input signal, that is, whether the receiver can equally amplify the frequencies in the signal and restore it without distortion.
More on the introduction of technical terms in the digital wireless image transmission process, Xiao Bian will continue to introduce for you later, if you have any needs for the company's products, welcome to inquire!
Digital wireless image transmission terminology introduced
The digital wireless image transmission device is a wireless transmission device that transmits audio and video signals from a signal source (a computer and a high-definition playback device) to a remote HDTV or a high-definition projector, and can well achieve lossless and no delay of 1080P/60 and 3D. Transmission, generally speaking, there are two main concepts of digital wireless image transmission. One is the transmission in the mobile and the other is the broadband transmission. Therefore, if necessary, we can develop high-definition video with a wide frequency band during high-speed movement. For a wireless image transmission system for transmission, it is necessary to first solve the two major problems of echo interference caused by multipath propagation, frequency resource usage and gradual saturation.
