A few days ago, CSCTRUCK held a departure ceremony for the delivery of street cleaner sweeper trucks to the Hong Kong SAR, which was also the first mass appearance of street washing vehicles. As a vehicle sold directly to the Hong Kong Special Administrative Region, the new model not only needs to meet the local truck usage habits in Hong Kong but also needs to meet the high requirements of the municipality in street cleaning operations.
The Hong Kong street sweeper trucks we saw this time were the first commercial mass production of the CSCTRUCK four-door model.
The reason why the new truck adopts a four-door design is entirely due to the needs of local street cleaning operations in Hong Kong. In Hong Kong, a street sweeper truck needs to take 6 people, and the position of each person corresponds to his work scope: the person in the driver’s seat is responsible for driving; the co-pilot is responsible for controlling the cleaning equipment on the truck through the interior panel; The second row can theoretically accommodate 4 people who need to manually clean the road in narrow roads that are inaccessible to vehicles.
There are two road washing water spray devices designed under the front bumper of the vehicle, which can provide two different working modes of low pressure spray water and high pressure cleaning. Under the low-pressure sprinkler mode, it can cover a maximum street width of 16 meters; during high-pressure cleaning, the water flow can reach 100L/min, and the flushing pressure is 10MPa.
The panel that controls the vehicle cleaning equipment is designed at the platform position of the cab. The panel is also designed by Qingdao Heavy Industry. Although it looks like a circuit controller, it is connected to almost all the electrical equipment of the vehicle. The execution and fault prompt of a cleaning function is realized through this panel. On the operation control panel, the operator can not only switch between the high and low pressure of the water spray equipment but also adjust the flow and pressure of the water spray to achieve the best cleaning effect.
Street washing vehicles in Hong Kong not only have strict requirements on the cleaning performance of the road surface, but also require the vehicle to have excellent operability, and the configuration of the automatic transmission has been added to the manufacturing standard sent to CSCTRUCK. The CSCTRUCK Hong Kong Street Washer Sweeper Truck we saw today is equipped with an Allison automatic transmission. The operation mode and shifting experience are almost the same as those of an automatic passenger truck, which is greatly improved. the driving experience of the driver.
On the Hong Kong street sweeper truck built by CSCTRUCK, the huge water tank is the largest component in the upper part. Although it only exists as a container for tap water for street cleaning, the interior of the water tank uses high-end technology. As mentioned above, Hong Kong has very strict requirements on vehicle quality, and CSCTRUCK has also done a lot of work on lightweight improvement.
After a long period of tests and multi-party demonstrations, CSCTRUCK finally finalized the material of the water tank: the tank itself and the pipeline are made of 316L stainless steel, and except for the parts that are in contact with the medium, the material is used without affecting the structural strength. Aluminum alloy design. In this way, the vehicle not only meets the requirements of the Hong Kong government for the curb quality of street sweeper vehicles but also improves the anti-corrosion performance.
In addition, the Hong Kong government also has extremely high anti-corrosion requirements for street washing tanks, that is, they must meet food-grade standards so that when there is a large-scale water outage, street washing vehicles can be temporarily used as drinking water for residents. Therefore, before delivery, CSCTRUCK’s Hong Kong street washing vehicles not only need to undergo equipment reliability inspection by the Hong Kong Electrical and Mechanical Services Department but also need to pass the food safety inspection by the Hong Kong Food and Environmental Hygiene Department.
In order to facilitate the manual cleaning operation by the staff in the narrow streets and alleys, the low-pressure reel on the rear platform of the vehicle is wound with a low-pressure rubber water pipe of 100 meters. As a digression here, women are generally selected to be responsible for manual cleaning in Hong Kong, because they are more careful than men when cleaning. In Hong Kong, if a sweeper spills water on passersby, there will be administrative complaints.
The retraction and release of the rubber water pipe can be realized by the motor on the body, which saves the tedious manual operation. In general Hong Kong street washing trucks, the motor operation buttons are only installed at the rear of the truck, while CSCTRUCK Industry has fully considered a variety of working conditions in the design, and additionally uses a wireless remote control so that the staff can remotely control the location outside the vehicle. The retraction and release of the water pipe make manual cleaning more convenient and labor-saving and have been well received by the purchasing organization.
The chassis of this street sweeper washing truck is the same in appearance as the Sinotruk T5G, but it has actually been completely redesigned. The previous ordinary T5G is a product built according to the characteristics of road transportation in mainland China. In order to ensure sufficient carrying capacity, the vehicle has a high self-weight. According to the requirements of Hong Kong, the quality of the whole vehicle is controlled within a very strict range, which makes CSCTRUCK have to abandon the previous solution and carry out a lightweight design, which includes measures such as miniaturizing some equipment and replacing materials.
This street washing sweeper truck is equipped with an MC07 29-60 MAN technology diesel engine. After working with the latest after-treatment device, the exhaust emissions can reach the Euro VI standard. In terms of performance, the engine can output a maximum of 290 horsepower and a maximum torque of 1150Nm, which can support the street washer to travel at a speed of 70km/h.
