Urban dump trucks are very important to a city. All urban infrastructure projects are inseparable from urban dump trucks. Nowadays, urban dump trucks are developing towards safer and more environmentally friendly, especially since many cities have implemented National VI emission standards in advance, and dump trucks are at the forefront.
SINOTRUK HOWO, this name is well-known in the domestic truck circle! In 2005, SINOTRUK HOWO was born. It has been 15 years since then. Even though later models such as HOWO A7, HOWO T7H, HOWO T5G, and even HOWO light trucks were launched, the truck closest to the style of the original HOWO is still in service, that is HOWO-7.
The front face of HOWO-7 was revised around 2010 compared to the first-generation HOWO model, and changed to the shape of the current HOWO-7. The front face has been improved with a more layered feel, but it is still the same as that year. Style, like a battle-hardened veteran, is still on the front line of charge. The rearview mirror is the most traditional split type, which I believe many card lovers who have driven for many years are familiar with. There is no electric adjustment or heating of the rearview mirror. It is purely manual adjustment, which is very rough. The air intake grille adopts a three-level design, and the style is similar to that of the Mercedes-Benz Actros MP3, making the front face look more layered. “HOWO” and “400″ represent the car model and engine horsepower respectively, which is more sophisticated than the door logo. direct. The headlights we are most familiar with are on the bumper. The position lights, high and low beams, and turn signals are integrated into the headlights, using halogen light sources that are commonly used in trucks. The two lights at the bottom are combined together, one is a fog light and the other is a fill light. When driving on the construction site, the brighter the lights, the better. Because the road conditions are not very good when the dump truck drives to the construction site, the chassis of the dump truck is very high, and this HOWO-7 is no exception. The thick anti-drilling beam is exposed, which is not only in compliance with regulations, but also for safety reasons.
HOWO-7 adopts a 6×4 drive form, with a dump truck length of 6 meters. It is a common model among urban muck trucks of this level, with a wheelbase of 3425+1350mm. A muck truck of this size is relatively flexible and easier to drive on urban roads. Looking at the cab from the side, the lines are tough and the cab is very spacious longitudinally. The sleeper window adopts a closed design, so that the light in the sleeper position is relatively dark, allowing for a better rest. Under the sleeper is an external tool box, which can be opened from the side of the main driver’s seat. Jacks, car arresters, tire changing tools, etc. can be placed here for easy storage and will prevent the cab from being stained by oil. There is no external tool box opening on the right side of the cab, but it is just designed symmetrically. If there is an external storage box on the right side, I believe it will add a lot of points to this car.
Compared with whether the appearance is cool or not, the driver pays more attention to the chassis performance of the vehicle. After all, this is a vehicle that must be driven on comprehensive road conditions such as construction sites and urban roads. Passability, vehicle speed, load-carrying capacity, etc. all require special attention. point. The Weichai WP10H400E62 engine is the heart of this car. This inline six-cylinder turbocharged diesel engine has a displacement of 9.5 liters and can output a maximum power of 294 kilowatts, a total of 400 horsepower, and a maximum torque of 1,900 Nm. The rotation speed is 1200-1300 rpm, and the rated speed is 1900 rpm. Matched with the WP10H engine is the Sinotruk HW19712 gearbox, which has 12 gears. The highest gear is a direct gear with a speed ratio of 1. The main box of this gearbox has a straight-tooth double countershaft structure, and the auxiliary box has a planetary structure. The maximum input torque is 1900 Nm. In addition, an HW50 direct-connected power take-off is installed on the gearbox for lifting the dump car. As for the front axle, this car is equipped with an HR9 front axle, which uses a multi-leaf spring suspension with 9 steel plates. The front axle brake is a disc brake, and a protective cover is added to the entire braking system to effectively prevent splashing. The stones may damage the brake discs and calipers, but this design is still very thoughtful. The rear axle uses a China National Heavy Duty Truck AC16 model wheel-side reduction axle with an automatically adjusting arm. The rear axle speed ratio is 4.77. The rear axle uses a traditional drum brake, which has stronger braking force. In addition, the rear axle is also equipped with a lateral stabilizer bar, which ensures the driving stability of the vehicle when driving on complex road conditions such as construction sites. The rear axle steel plate adopts a multi-leaf spring suspension with 12 steel plates. The fixing bolts are arranged in an inverted riding style with the fastening nuts at the top, which makes it easier to disassemble and assemble the riding bolts during later maintenance and repairs.
In terms of the engine air intake system, this vehicle is equipped with a special air filter for dump trucks as standard. Compared with ordinary road vehicles, the place where the dump truck works is very dusty, and the special air filter can better filter and precipitate the inhaled air. to ensure the cleanliness of the air entering the engine. The urea tank and the 300-liter aluminum alloy fuel tank are arranged side by side on the left side of the frame. The location of the filling port is very convenient. Whether it is refueling or adding urea, it is very convenient for the driver. The height of the side guardrail is just enough for the two tanks. Space is left for the filler port. There is also a battery and two iron gas storage tanks on the right side of the frame. There is also an iron gas storage tank under the car. The three gas storage tanks can provide sufficient compressed air to the parts of the vehicle that use air. In particular, sufficient compressed air can better ensure the work of the braking system. Braking is the most important element of a car that cannot be neglected. The outside of the engine exhaust pipe is covered with thermal insulation material to protect the exhaust gas temperature and enable better SCR post-processing. As mentioned earlier, this car’s post-processing system does not have EGR and uses DOC+DPF+Hi- SCR technology.
The cab of HOWO-7 adopts a four-point mechanical shock absorber suspension. If the shock absorbers are adjusted in place, the comfort of the entire cab is no less than that of models with airbag suspension. Compared with the hard-connected cabs of previous old cars, the mechanical shock absorber The shock comfort is also very high. The boarding pedal is a two-level design. The pedal is made of composite material as a whole, and the stepping part is made of stainless steel with anti-slip hollow design. The most common things on the construction site are mud, water, soil, stones, etc. If they stick to the soles, they can be scraped off on the pedal and passed through the hollow mesh. If dropped to the ground, it will not stain the cab. The main driver’s seat is airbag shock-absorbed. It only supports inflation and deflation, elevation adjustment, and seat height adjustment. It should be regarded as the most basic airbag shock-absorbing seat. Such a seat is more than enough to meet the driver’s comfort requirements for short-distance driving. On the left hand side of the main driver’s seat is the operating handle of the dump car. There is an indicator mark on the top of the ball head, which is shaped like an air brake.
Although HOWO-7 looks very tall, there is a convex floor in the middle of the cab. The front of the floor is an open storage space, which can store documents and sundries. The two cup holders are convenient for placing water cups and ashtrays. The middle storage space The storage slot can hold cards or cigarettes. Although dump truck drivers only travel short distances and do not have to sit in the driving seat for long periods of time, it is common for them to stay up late working. Sometimes, in order to meet the construction deadline, two drivers work in shifts, and the sleeper must be indispensable. Sleeping in the car is also common for garbage truck drivers, so the width of the sleeper must be enough for a burly truck driver to lie down.
After reading so much, are you already tempted to buy a HOWO-7? If you are worried about insufficient budget, it doesn’t matter. We at CCMIE provide a variety of second-hand vehicles for customers to choose from, with high quality and low price. Welcome to consult.
