The safety of construction vehicles has received more and more attention in recent years, and many OEMs have made different solutions to this, and local governments have also made appropriate changes to regulations. As a result, the regulatory version of the muck truck was born, and the main engine factory made different configurations for different regions, including the upper part announcement.
Safety is not to be underestimated, China National Heavy Duty Truck has made great improvements to the safety of vehicles while launching the regulatory version of the model. A good example is the current mainstream Howo TX muck truck.
Cab for safety:
The body color of howo TX dump truck has green, blue, orange, yellow, white and other customized color numbers, which meets the requirements of policies and regulations in many cities across the country. And in terms of appearance, Howo TX is full of European flavor, inverted trapezoidal middle net with gold logo and decorative strips, full of visual beauty, the roof standard sun visor can also block part of the light when driving backlight, to avoid affecting the driving line of sight.
The cab is equipped with an electric flip mechanism, the flip button is moved from the back of the previous right front fender to the inside of the front hood, and there is a protective cover on the control mechanism. This design can not only reduce the blind spots and dangers during operation, but also avoid the damage caused by the face shield not being opened when flipping, killing two birds with one stone.
The front bumper of the Howo TX has ultra-high ground clearance and approach angle, which means that the car has very good passability, and is equipped with a water tank guard plate behind the bumper, which protects the radiator on the chassis. The bottom of the bumper is provided with a reinforced steel drill bar according to the requirements of national regulations, in the event of a traffic accident, this drill bar can avoid the car from being involved in the chassis, and the safety of urban driving is greatly increased.
The headlights adopt a split design, the internal lamp beads are halogen light, for the engineering vehicles that often go in and out of the construction site, the split type of lights are less expensive to replace after damage, and it can be done which one is bad.
Driving line of sight is a highlight of the Howo TX dump truck, where all the patch blinds are high curvature lenses with a wider range of views. And there is a design observation window at the right door, which is what old drivers often call the foot window or "OK window". This observation window can better reduce the blind spot of the vehicle's line of sight, facilitate the observation of the right side side side by side scene, and avoid hitting the sudden pedestrian or vehicle.
After adding the observation window, the car glass can not be fully opened, and the co-pilot only reserves a small part of the openable area.
Super comfortable interior, the car machine can view the surrounding image:
The working conditions of the muck truck are often in and out of the construction site, and the bumpy sections are mostly, so it is especially important to have a good seat at this time. The main driver of the Howo TX dump truck adopts the airbag shock absorbing seat of SINOTRUK MAN technology, with ultra-soft damping adjustment mode, integrated seat belt, and supports multi-stage pneumatic waist support. Such seats, completely unafraid of bumpy sections, provide high comfort for the driver and reduce driving fatigue.
In terms of interior, the workbench of the Howo TX is based on and optimized with reference to the design of German MAN, and the wrap-around table design is made in the main driving area, so that all the buttons are inclined to the driver's side for easy operation. The remaining positions are moved forward to allow more space in the cab, and then multiple storage spaces are set up on the workbench to increase overall utilization.
The car is equipped with a multi-functional steering wheel, a large central control display screen and automatic constant temperature air conditioning as standard, so that this muck car can be comparable to the logistics car in the cab configuration, howo TX has an electrical horn conversion, which can be adjusted to a lower decibel electric snail horn when driving in the city, and the horn switch is not set on the airbag cover, but at the end of the steering lever on the left side.
In order to improve driving safety, Howo TX dump truck is equipped with the original four-way imaging system, and concentrated on the central control machine display, the driver can observe a state around the current vehicle through the image, especially the rear image, it is no exaggeration to say that this image can reduce the vast majority of accidents caused by reversing.
Switches like power take-off, inter-shaft differential lock and inter-wheel differential lock are all integrated in the central control position, and this function key related to the work operation is all equipped with a lock plate, which needs to be turned on when opened to avoid the damage caused by the wrong operation of the power take-off/differential.
The sleeper of the Howo TX is very large in the construction vehicle, and there are widenings in front and behind, although the frequency of the city muck truck spending the night in the car is not high, but the sleeper is still very comfortable when waiting for rest. And there are three observation windows behind the sleeper, so that the driver can carefully observe the situation on the left and right sides of the vehicle when it is on the roof.
Weichai WP12 is coming, born for engineering:
Howo TX is a dual-power model, optional man technology MC engine and Weichai engine two models, this TX 430 dump truck is powered by Weichai Blue Qing WP12.430E62 engine, displacement 11.6L, maximum horsepower 430 hp, torque 2100N .m, maximum torque output speed of 1000 rpm - 1400 rpm.
The WP12 engine is generally better in power performance than the previous WP10.5 machine, the displacement is slightly larger and the stability will be better, and the torque is also 100N .m higher than the P10.5, and the power is better, which is the same as the torque value of the MC11 440 horsepower model of the national sixth.
Details determine success or failure, in the muck truck, Howo TX is still equipped with radiator insect net, which is mainly to prevent bad road conditions of flying stones or willows to cause damage or blockage to the heat sink.
There is no doubt that the heavy truck engineering vehicle is equipped with the 25712 gearbox of the HW series, which has a total of 12 forward gears and 2 reverse gears, with synchronizers, which will be easier to hang gears. The housing of the gearbox is made of aluminum alloy, which can reduce the weight of the body and improve the heat dissipation effect of the internal oil.
The vehicle drive axle is a parallel man technology 16-ton class wheel side reduction bridge, the bridge shell has a large ground clearance, good passability, and the vehicle's detractory will also increase after further reducing the speed and twisting of the planetary frame on the wheel side. The axle speed ratio is 5.26, which is suitable for driving in urban and expressway road conditions, which is convenient for medium and long-distance operations and helps to improve the efficiency of vehicle transportation.
The load-bearing capacity of the vehicle does not have to worry at all, the number of steel plates of the Howo TX is 11/11/12, and the rear suspension group is fixed by two sets of inverted riding cards. Moreover, the axle load of the two axles alone reached 32 tons, plus two 7.5 tons of front axles, the 12.00R20 meridian wire tires and high-strength steel rims of the whole vehicle, which can fully cope with the total weight of 31 tons and the standard 5.6 meters loading and unloading of all the materials and working conditions.
For the 5.6-meter muck truck, the fly in the ointment is the fuel tank capacity, because the wheelbase limit can not be too long, but also because of the ground clearance, the upper and lower size can not be too large, so this type of car fuel tank capacity is generally in the range of 300 to 350 liters.
Three-layer frame + thickened subframe, this combination of load carrying capacity is certainly self-evident.
Editor's Note:
In fact, like the current 5.6-meter muck truck in terms of safety, it is already better than the previous popular 7.6 muck car, the same braking conditions, the total weight of the 5.6 m muck truck will be lower, coupled with the speed limit of the regulations, the safety is much better. On this basis, Sinotruk Howo TX has added some humanized configuration and design to solve the problem of blind spots of muck trucks, and the enhancement of bearing capacity is also an improvement of vehicle reliability, providing users with higher value solutions.
