On May 10, 2012, nine Mercedes-Benz wet road sweepers from the United Kingdom formally debuted in Qingdao Huangdao. In the future, these will be responsible for the road surface cleaning of major roads and lawns in Huangdao District. Each of these vehicles costs 2,070,000 yuan. It uses the world's most advanced cleaning technology, can automatically "smoke" bricks, eliminate road spillage, and has a special vacuum cleaner to clean the lawn and rain scorpions.
Mercedes-Benz came on the road for the street
The nine sweepers were shipped by ship and it took more than a month to arrive in Qingdao from Britain. Yesterday morning, the reporter saw them at the parking lot of the municipal sanitation garden center in Huangdao District: white body, about 5 meters in length, sprinkler device under the front of the vehicle, and a total of 5 disc brushes on the left, right, and middle positions. The bristles are made of steel wire. Each dish brush is also equipped with a corresponding sprinkler device. This will enable the vehicle to clean the surrounding garbage in an all-round way and will not generate dust pollution during cleaning.
The reporter boarded the cab of one of the cars and was seated as soon as possible, and the driver's seat began to float automatically. "The seat can be estimated based on the driver's height, and then automatically adjust the level." Said Chen Xin, director of the Huangshan District Municipal Sanitation Garden Center. When the reporter left the seat, the driver's seat slowly lowered to its original position.
It is understood that these 9 vehicles are "mixed" Mercedes-Benz. The chassis and front of the car are made in Germany. The cleaning equipment on the car is produced in the UK. The overall function of the car is very eye-catching, according to reports, after removing the cleaning equipment, the original car chassis can be directly converted into a truck or RV.
Increased efficiency can sweep the earth but also suck bricks
The reporter noted that on the left and right sides of the Mercedes sweeper, a large plastic tube with a diameter of about 20 cm was installed. These two "like noses" can clean up the road and spill stones and sweep stones. This is one of the biggest highlights of the sweeper.
The sanitation workers demonstrated to the reporter that a worker randomly scattered some gravel on the ground. Another worker stared at the stones and piped, and only listened to the sound of a few bangs. All the gravel were cleaned. It is understood that when the suction reaches its maximum, the dust particles can weigh more than 2 kg. "It can easily suck a brick." Chen Xin said.
These sweepers can work at speeds of 10 to 15 kilometers per hour, and can effectively sweep 90,000 to 150,000 square meters of road surface per hour. The average sweeper works at speeds of 8 to 10 kilometers per hour, and the sweeping area is very limited. If the speed reaches 10 to 15 kilometers, there will be incomplete garbage cleaning. After the new sweeper is on duty, it will greatly increase work efficiency. A sweeper’s work can be equivalent to the workload of hundreds of workers.
Maintenance is not difficult to repair in Chengyang
Ordinary sanitation vehicles are generally around 200,000 yuan, and the more advanced domestic sanitation vehicles are between 800 and 900,000 yuan. The Mercedes-Benz sweeper vehicles purchased in Huangdao District have a higher cost, and it is also very troublesome to maintain them at ordinary times.
Chen Xin said that these sweeping vehicles are also used in other cities across the country. The key to the entire vehicle is not the front and the chassis, but the sweeping facilities on the vehicle. “These parts have maintenance locations in Chengyang District. For fragile parts such as disk brushes, they will be replaced in about 2 months. The hydraulic devices in the vehicle will be replaced once a year. Each replacement can be selected according to the specific situation. Or domestically-made parts, the price is not much different from ordinary vehicles."
Use wet water to clean the road without dust
Is it necessary to use a Mercedes-Benz car on a sweeping road? In response to reporters' questions, Chen Xin said that the old type sweeper had no sprinkler device, and it was like a “sandstorm†when cleaning roads. It was likely to cause secondary pollution. Even with some wet road sweepers with sprinklers, the sprinkling and cleaning could not be synchronized. The operation also easily causes dust. In addition, some vehicles have poor airtightness and can not play a role in dust collection. In particular, some large solid wastes have certain difficulties in cleaning. These newly introduced Mercedes vehicles can well solve the above problems.
In the development of cities, various types and performances of equipment are required to be used together, so as to effectively improve the cleaning efficiency. For example, these newly-purchased sweeping vehicles will be mainly responsible for main roads, emergency spillage accidents and relatively heavy sweeping work, which will not only improve the cleaning efficiency, but also reduce the burden on sanitation workers.
It is understood that in 2012, Huangdao District invested a total of 50 million to purchase 17 road sweepers, 160 electric fast cleaning vehicles, 6 sprinklers and small sweepers, 3 wash trucks, and 2 sewage suction trucks. By the end of the year, the road mechanization sweep rate will be increased from 37% to 75%.

It is understood that the city’s urban mechanized sweeping rate is currently 60%, and the main roads have reached 90%. Chen Shiwei, director of municipal public sanitation department of the Municipal Public Administration Bureau, told reporters that in order to further improve the cleaning efficiency, the city will promote the experience of Huangdao District in 2012 and introduce a number of more advanced domestic sweepers for use in key areas such as scenic spots and main roads. At the same time, it cooperates with other small-scale equipment to run synchronously, and the mechanized cleaning rate of urban areas will reach 80%.
