The emergency lane is mainly used for rescue emergency vehicles, police vehicles and other emergency situations, and ordinary vehicles are prohibited from driving or staying. However, it does not mean that it cannot be used. When the vehicle encounters an emergency situation, it can also use emergency lanes, such as a vehicle suddenly punctured, vehicle accidents, etc. In general, any social vehicle is not allowed to stay in the road. There is a clear provision that motor vehicles should enter the emergency lane or stop on the highway in a non-emergency situation.
Even in the case of an emergency, using an emergency lane requires a series of operations so that other vehicles can travel safely. First of all, to ensure that the vehicle must stay within the lane of the emergency lane, within the white line, the vehicle should be parked as close to the high-speed fence as possible away from the high-speed traffic lane. In order to give tips to other vehicles, there are several points that need to be done: 1. Turn on the vehicle's double flash; 2. Set up a warning sign at 150 meters behind the vehicle; 3. Visibility is low, such as rain, night, etc. The distance of the warning sign is properly increased; 4. After the vehicle stays in the emergency lane, the drivers on the vehicle, including passengers, need to leave the vehicle and stay in a safe area. In addition, the driver’s friends need to be reminded that when the emergency vehicle is parked, it is still necessary to avoid cornering on the road to prevent accidents from occurring due to the poor line of sight during the driving of other vehicles. At the same time, if the situation is very critical, they cannot solve the problem, or they must call the highway to call for help to protect their personal safety.
If you use emergency lanes in non-emergency situations, you will be subject to certain penalties. The penalty is between 200 yuan and the deduction is about 6 points. Therefore, it is still necessary to strictly enforce the emergency lane usage rules so as to avoid unnecessary trouble and danger. There are two other things to note: traffic jams on a high-speed road are not emergency situations and emergency lanes cannot be used. Vehicles on Highway 2 need to be overhauled, flash lights need to be turned on, and the vehicles are safely moved. A place that does not affect traffic.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.
The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, and a reciprocating or rotary table. The chuck holds the material in place while it is being worked on. It can do this one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-ferromagnetic and nonmetallic pieces are held in place by vacuum or mechanical means. A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available.
Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on.
Typical workpiece materials include cast iron and mild steel. These two materials don't tend to clog the grinding wheel while being processed. Other materials are aluminum, stainless steel, brass and some plastics. When grinding at high temperatures, the material tends to become weakened and is more inclined to corrode. This can also result in a loss of magnetism in materials where this is applicable.
