Howo dump truck: technical specifications, manufacturer, reviews

Products originally from China are successfully sold all over the world. It is perceived as inexpensive, but varied. And this can now be said about cars. Increasingly, you can see Chinese-made cars and trucks on the roads. The latter include the Hovo dump truck, the technical characteristics of which allow it to be used for transporting goods in various sectors of the national economy. It is used for transporting a variety of materials, including in bulk without packaging.

What can you say about the manufacturer?

The Hovo dump truck is manufactured by the Chinese company Sinotruk. It is a recognized global manufacturer of special-purpose trucks. Along with dump trucks, the company produces tractors, concrete mixers, trucks, as well as spare parts for its models. All the company’s products are produced under two brands: “Khovo” and “Hania”. Both brands are well known on the Russian market.

To develop the model, the company relied on the experience of global automakers. This made it possible to create a worthy version of the car, competitive among representatives of its class.

For the same purpose, the corporation purchased and installed modern computerized lines at its production. This allowed the organization to take one of the leading positions among manufacturers of heavy-duty and utility vehicles in China.

The Chinese Hovo dump truck is known not only in its own country. They are recognized in the Russian, European and American markets.

Load capacity

This is probably the fate of dump trucks, so that they are constantly overloaded. Almost all KAMAZ owners increase the sides in order to transport more tons of cargo and get more money, since dump trucks are usually paid for the number of tons of cargo transported. Moreover, carriers are not afraid of high fines; this amount is included in the delivery cost. And possible breakdowns do not bother them; they will fix it anyway and continue to work.

But the situation worsened greatly with the advent of Chinese dump trucks. The reason lies in their oversized bodies. Now we'll explain everything.

To understand how many tons of cargo can be transported in a particular body, its volume should be multiplied by a special coefficient (for crushed stone - 1.4, for dry sand - 1.6, for wet sand - 2.0, for earth - 1, 7).

For example, the volume of the body of our KAMAZ-6520 is 12 cubic meters. If we load it with sand “on the sides”, we get 19.2 tons (12 * 1.6). The rated load capacity of this dump truck is 20 tons. Thus, there is no overload.

If we take a three-axle Chinese dump truck, its platform volume is 18 cubic meters, which means it can transport almost 29 tons of sand. Only the permitted carrying capacity of such a dump truck from China is only 22 tons.

Four-axle “Chinese” vehicles generally have a body of 25 m3 and a load capacity of 25 tons. Although they can transport all 40 tons. The result is a 15-ton overload. Great, isn't it?!

It is not known what the Chinese engineers were thinking!

Where is a car of this brand used?

The main purpose of a dump truck is to transport goods. This can be building materials (concrete, sand, asphalt, crushed stone), soil, agricultural feed and root crops, garbage, and so on. This determines the main areas in which the Hovo dump truck is most often used:

• Construction.

• Agriculture.

• Industry.

• Utilities and so on.

The cost of purchasing equipment of this brand pays off quite quickly. This is due to the fact that a Howo dump truck can make not one, but several trips per working day. When the vehicle is heavily loaded, its technical characteristics do not deteriorate.

Device

In the manufacture of the supporting structure of Hovo A7, high-strength materials are used (strength level over 820 MPa). The use of a longitudinal beam, complemented by a U-shaped crossbar, increases the resistance of the frame and chassis to bending forces. The special design of the vehicle and the use of advanced materials make it possible to reduce the overall weight of the vehicle.

Howo A7 uses different types of suspensions. The most common configuration is as follows: at the front there is a dependent suspension on longitudinal semi-elliptic springs with transverse stabilizers and hydraulic shock absorbers, at the rear there is a balanced suspension with multi-leaf springs. The basic configuration includes several passive safety systems. Thus, an underrun protection device is located inside the bumper, which prevents a collision with a passenger car in the event of a frontal collision. In a frontal collision, the cabin moves towards the body.

The initial version is equipped with tubeless tires with increased wear resistance and low thermal conductivity. Due to this, the vehicle's efficiency increases by 5%.

For the Hovo A7 series, several transmission options are offered. The most common are a 10-speed manual transmission with a 430 mm single-disc clutch and a 16-speed automatic transmission with manual shift mode and electronic control. The power reserve is transferred to the rear wheels (the rear axles have inter-wheel and inter-axle locking).

The car is equipped with disc mechanisms at the front and drum devices at the rear. The mountain brake reduces the use and wear of the brake system when moving downhill. This increases the service life of the brakes.

• ABS “Wabco” (improved version) – anti-lock braking system;
• EBL – brake force limiting system (reduces the likelihood of skidding when cornering);
• TPM – tire pressure monitoring function;
• ASR is a traction control system that prevents tires from slipping on wet and icy roads.

Already in the basic version, the Howo A7 has 5 cab options with a cabover layout. The driver's workplace is located above the engine and is mounted on 4 supports and air suspension. When creating the cabin, advanced solutions are used, and its design was developed by Italian specialists. Large windows and mirrors provide maximum visibility. A special safety steering wheel design and seat belts increase the level of protection. There are no sharp corners in the cabin, and the upholstery is made of non-flammable materials. All this is aimed at ensuring maximum safety during work.

For ease of operation, the Hovo A7 is equipped with electric drive and heated mirrors, and electric windows. The basic package also includes:

• electrical connector;
• side sun visor;
• cigarette lighter;
• many compartments;
• cup holder;
• electrically driven lifting mechanism;
• adjustable steering wheel.

The Howo A7's interior is large enough to allow the driver to move freely inside the cabin. The chairs can be customized to suit individual needs. An optional seat with air cushion, lateral and lumbar support and electric heating is available. There are keys on the steering wheel to control the radio. The instrument panel has LED backlighting with indicators that are easy to read at any time of the day. Current information about the vehicle is displayed on the on-board computer.

Upon request, high cabins with sleeping places are installed on cars of the series.

Maintenance of Howo A7 is simple. To access the engine, the cab must be tilted forward using a pneumatic system. Refueling and service points are accessible from the ground (located at eye level).

Car Features

Howo dump truck is manufactured taking into account all modern requirements and standards. Along with good technical data, it has an increased level of comfort inside the cabin, creating favorable conditions for the driver to work. Some experts claim that the dump truck cabin resembles cars.

But the price of Chinese and Swedish trucks differs significantly. Equipment from China is much cheaper to maintain than its analogues. In addition, she is not so “picky” and requires less attention. Adapted to work in different climatic latitudes, dump trucks can withstand even the most difficult conditions. At the same time, the owner spends less financial resources when buying spare parts.

The Hovo dump truck features comfortable working conditions for the driver. This is achieved through the equipment installed in the equipment.

How to prepare for use?

After purchasing a Hovo dump truck, it is recommended to carry out preventive work and first of all change the tires, since it was noted that Chinese tires generally do not differ in quality and reliability. According to reviews from the owners of such dump trucks, in the vast majority of cases, original tires can provide a mileage of about 40,000 km, while the minimum service life of some owners was only 15,000 km.

The main reason why the tires originally installed by Hovo (dump truck, photo above) have such a short life is that the wheels use an inner tube. It is not able to withstand heavy loads, so it can fail at any moment. As a result, it will be much cheaper to immediately change the entire set of rims and wheels, and install tubeless tires on European rims.

Also, many users who purchased a “Hovo” (dump truck, photo above) often point out such a drawback of this vehicle as the lack of sensors on all wheels, while experts recommend that such devices be used during operation of any vehicle. After all, if at one moment the driver is unable to keep track of the pressure (which is quite common in dynamic and rather harsh operating conditions), the wheel will simply become unusable, and its cost will be several tens of thousands of rubles. Installing sensors on all wheels of a dump truck will cost approximately the same, so such an investment can be called justified.

Vehicle options

Dump trucks are equipped with options such as:

• Air conditioner.

• Heater.

• Ventilation.

• Climate control.

• Adjusting the seat position.

• Seat heating.

• Changing the position of the steering column.

• Radio.

• Electrically driven cab tilting.

These features allow you to sit comfortably to get your work done.

Device

Models of the Howo Sinotruk family are built according to a similar scheme. The frame is a spar-type frame made of durable steel. The frame serves as the basis for mounting the main units and elements.

The front part uses a dependent suspension with semi-elliptic springs, hydraulic shock absorbers and a transverse stabilizer. At the rear, a balancer system with reaction bars and semi-elliptic springs is used. The suspension is able to withstand increased loads.

Most versions of Howo Sinotruk are equipped with a reliable 9-speed non-synchronized manual transmission (8 forward speeds, 1 reverse speed), complemented by a 420 mm single-plate clutch. The driving wheels for all modifications are the rear wheels (there is an inter-axle and inter-wheel differential lock).

In the initial version, Howo Sinotruk trucks boast a 2-circuit braking system with ABS function and all-round drum elements.

The series has several cab options with the following features:

• electric drive for tilting (facilitates access to maintenance elements);
• climate control or air conditioning;
• adjustable steering column with hydraulic booster;
• heated seats;
• powerful heating system;
• driver's seat settings;
• ventilation.

Howo Sinotruk's cabin has a number of features. Among all Chinese trucks, this series has the largest windshield that meets European safety standards. The driver is provided with special 2-lock seat belts with improved characteristics. The ergonomics of the cabin are performed at the highest level.

The cabin itself was designed by Chinese developers by analogy with European models. The 4-post floating suspension dampens vibrations in the cabin regardless of the type of road surface. Under any circumstances, Howo Sinotruk's cabin remains stable. For models with power over 290 hp. It is planned to install an air conditioner with a heater. Versions with a berth allow you to freely sleep and relax after a long trip.

Howo Sinotruk can be equipped with a wear-resistant body with different volume options with side or rear unloading. The container is heated by gases from the exhaust, allowing operation at sub-zero temperatures.

Technical characteristics of the car

The manufacturer developed the Hovo dump truck with the aim of introducing it to the international market. This desire could not but affect the car's performance.

High-quality materials are used to produce reliable parts and components. Thanks to this, the ability to withstand wear and abrasion of all components is quite high.

The car is equipped with a four-stroke diesel engine. Power, depending on the modification, can vary from 336 to 375 horsepower. The volume of the power unit is 9726 cubic centimeters.

Engine with six cylinders arranged in a row. To improve technical characteristics, an intercooler and turbocharging are installed.

• Width 2.3 m.

• Height 1.4 m.

The curb weight of the Hovo dump truck is fifteen tons. And its carrying capacity reaches forty tons.

The lineup

The model range of Howo A7 dump trucks is quite wide. The line includes articulated equipment and mining dump trucks with a lifting capacity of up to 40 tons. The A7 6x4 and A7 8x4 models are especially popular on the Russian market. This is due to their high level of productivity and relative cost-effectiveness in operation.

Howo A7 6x4

This articulated dump truck comes in a 6x4 wheel configuration. The model is equipped with all-wheel drive, thanks to which we can talk about a high level of cross-country ability. This versatile machine can be used in the harshest climatic conditions. Through its use, bulk cargo is transported. Howo A7 is widely used on construction sites and in quarries.

A distinctive feature of the Howo A7 6x4 model is its three-axle design. All wheels of the vehicle are driven, as a result of which we can talk about operation in the most difficult road conditions. The option of locking the cross-axle differential helps to increase the level of cross-country ability.

The dump truck frame consists of two separate parts, which are connected to each other by a hinge. This design feature allows you to fold individual parts in a horizontal plane and rotate the sections relative to each other. Here we can talk about minimizing loads on the frame while overcoming unevenness.

With a total weight of 15.3 tons, the load capacity of the dump truck is kept at 25 tons. The brake system of the machine has a closed design, which eliminates the possibility of moisture ingress. The use of oil protects the brakes from overheating, so the likelihood of failure of the mechanism is minimized.

A diesel power plant is characterized by an in-line design of cylinders. The use of additional filters prevents the possibility of dust entering the engine along with the incoming air.

Dump truck "Hovo": reviews

There is no car with ideal characteristics in all respects. This idea is repeated by the owners of the Hovo dump truck.

Externally, the car attracts attention. The cabin is comfortable for work. It's comfortable to sit behind the wheel. Good visibility. All the necessary levers are at hand, no need to reach for them. Sound insulation is good. During the cold season, the heating system copes with its task.

The body design facilitates the process of loading and unloading bulk materials. Tipping the body allows you to empty the load completely. There is nothing left inside. This speeds up the work.

Manufacturing defects are rare. Dump trucks usually serve well. The car is not the most economical. But fuel consumption is better than that of domestically assembled models.

There is quite good value for money. The new model can be purchased for 3.6 million rubles. The cost of used dump trucks averages 1.2 million rubles.

For such prices you buy a fairly reliable car, well balanced and with good ergonomics.

Driver's cabin

The basic cabin has 5 options. It is designed without a hood and is installed above the engine on air suspension and four supports. When developing the Howo A7 cabin, modern engineering solutions were used, so it is comfortable, convenient and ergonomic. This has a positive effect on the driver’s condition after a long shift.

Visibility is due to the installation of large windows and mirrors. The steering wheel has an injury-proof design, and seat belts protect the driver and passengers in the event of an accident. There are no sharp corners in the cabin, which also ensures safety, and the upholstery is made of non-flammable materials. Its shades are chosen in such a way that they do not irritate the operator.

For the convenience of controlling the power windows, electric drive and heated mirrors of the Hovo A7, a separate remote control is provided. The standard package includes installation:

• BEHR heating and air conditioning systems;
• side sun visor;
• electrically driven lifting unit;
• spatially adjustable steering wheel;
• a large number of compartments for things;
• cigarette lighter;
• place for a glass;
• electrical connector.

The large volume allows the driver to move around the cabin without any problems. In models A7-G and A7-P, the height of the engine tunnel is 170 mm. The driver's seat is comfortable and can be adjusted to individual parameters. Optionally, the HOWO A7 truck tractor is equipped with a luxury seat equipped with electric heating, air cushion, lumbar and lateral support.

The car can be equipped with a high cabin, which has two “sleeping bags” (modifications A7-G and A7-V). The lower one can be folded out and used as a place to relax or have lunch; it has seats and a table. The top shelf is quite wide.
