Wheels can directly influence casters
performance in load capacity, service life and working environment. When you
pick up the wheel, you should firstly consider the load capacity. The larger
the wheel diameter, the heavier load it can bear. Wheel material has different
characters, which decide the wheel material. For the hospital, quiet rolling and anti-vibration
are necessary. As for chemical industry, the wheel must be excellent in
chemical resistance etc. so when you pick wheels, wheel material is an
important factor. As for wheels service life, many factors, such as Wheel material,
environment and load capacity etc, put influence on it.

The Ultrasonic parking guidance system uses ultrasonic principles to install ultrasonic probes above each parking space, and tests whether there are vehicles parked on the parking spaces. The management system will collect and transmit the parking spaces to the server. The server then processes the data, and then the parking spaces guide information. The parking spaces that guide the display are fed back to the various entrances.
The video parking guidance system is equipped with a video detector above the parking space. Through this video detector, it can detect whether there is a vehicle in the parking space, can capture the vehicle photos and license plate numbers, and transmit this information to the server, after processing by the server. The parking guidance information is fed back to the parking guidance display at each entrance.
In general, the video parking guidance system is much more advanced than the ultrasonic parking guidance system. The video parking guidance system can combine the parking guidance function and reverse search function of a parking lot to achieve device sharing without guidance like ultrasonic parking spaces. System, if you want to achieve the reverse car search function, you need to install a separate card positioning machine, this will inevitably increase the amount of work. 
Two options for parking guidance
There are two main parking guidance systems on the market today: ultrasound technology parking guidance and video recognition parking guidance systems. What is the difference between these two parking guidance systems?
