Dump truck Ural 63685: technical characteristics, diagram

The Ural Automobile Plant is known as a manufacturer of heavy equipment that can drive literally anywhere. Vehicles from Miass have proven themselves to be excellent both in the army and in performing civilian tasks. They can be found in “hot spots” around the world, as well as in the Far North.

Ural-63685 stands out somewhat from the general model range - it is not like other cars produced under this brand. At the same time, it is a reliable and durable car, like its other “brothers”.

Platform

The car platform is represented by an all-metal structure, which is characterized by high strength and can withstand significant loads. The rear cover of the body folds back, and in the stowed position it is secured using special locks. Opening can be done automatically or manually, which is very convenient and practical.

We note the fact that the Ural 63685 was produced in several modifications, one of which could perform unloading not only backwards, but also using the side boards. Such vehicles were in demand in construction work, where there was limited space for maneuvering on construction sites.

LET'S SUM IT UP

At the end of the article, summing up the Ural dump truck 63685, it is noticeable that the company is striving to improve its vehicles so that they can compete with other brands of trucks. It’s very nice that the antediluvian bonneted cabs have finally gone into oblivion, and now there are cabover options, like European cars. Although, inside the cabin, the quality of the materials used, along with ergonomics, still suffers greatly. Too much free space was wasted away uselessly.

But the trump cards of this dump truck are that it has a large loading weight, good reliability and sufficient power. The machine also has small dimensions, which is perfect for use in urban environments. It is already noticeable that the company is on the right track to improve production, so we should expect more advanced versions with improved interior comfort in the future.

Power point

One of the main technical characteristics of the Ural 63685 car, like any other vehicle, is the type of engine, which determines the car’s power, fuel consumption, environmental class, etc.

The road-type trucks under consideration are equipped with YaMZ-7601 power units produced at the domestic Yaroslavl Motor Plant. This 4-stroke 11.15-liter engine:

• runs on diesel fuel;
• features a V-shaped configuration;
• has 6 cylinders and a pre-heater;
• equipped with a turbine with intercooler;
• complies with the Euro3 eco-standard;
• develops a power of 300 horsepower.

The ease of maintenance of the engine installed on the Ural 63685 vehicle deserves special attention. Thus, for daily checks and inspections of the internal combustion engine, it is not necessary to raise the cab of the vehicle.

Modifications of Ural 4320:

1. Ural 4320 – chassis with a basic metal cabin with a load capacity of 7000-9000 kg;
2. Ural 4320-19 – long-wheelbase chassis with a lifting capacity of 12,000 kg;
3. Ural 43203 – chassis with reinforced front suspension;
4. Ural 43204 – chassis with increased load capacity;
5. Ural 44202 – truck tractor;
6. Ural 43206 - chassis with a 4 by 4 wheel arrangement.

For cars, the Ural 4320 remains the base model. This truck is highly practical and designed specifically for the needs of the army. Its main area of ​​application is the armed forces. However, the machine is also used in the public utilities, forestry, construction, mining and commercial sectors. Here it is in demand as an all-terrain vehicle used for transporting people and equipment.

Transmission

The operating mode of the YaMZ-7601 power unit in the Ural 63685 truck is set via a 9-speed manual transmission equipped with YaMZ-239 synchronizers. You can move away and start driving the vehicle in question without a load from the 3rd speed of the lower gearbox row. For these purposes, the motor has enough power.

The combination of the gearbox and the Ural 63685 straw installation has proven its efficiency and performance. In addition, this layout makes the car very dynamic. This is confirmed by the fact that the car easily accelerates to hundreds of kilometers per hour even in full gear and at maximum load. In this mode, the sound of the engine is almost inaudible.

Price of new and used Ural 4320

The cost of a new Ural 4320 car varies significantly depending on the version:

• chassis - from 1.9 million rubles;
• on-board version - from 2.1 million rubles;
• onboard vehicle with CMU – from 3.8 million rubles;
• tanker – from 3 million rubles;
• log carrier - from 2.8 million rubles;
• cargo-passenger version - from 3.1 million rubles.

There are relatively few used Ural 4320s available. Here prices range from 0.3 to 1.8 million rubles. The cost is influenced by the condition of the car, year of manufacture, area of ​​use and equipment.

Suspension

The excellent technical characteristics of the Ural 63685 are largely determined by the front and rear suspensions of the dump truck, which have a similar design. At the front, twin semi-elliptic springs are used, working in conjunction with telescopic shock absorbers on both sides simultaneously.

As for the rear suspension, its structure is similar, but the difference is that it is reinforced with springs.

With such basic equipment, the Ural 63685 easily overcomes off-road conditions, and in the cabin the driver and passengers do not feel any significant inconvenience or discomfort.

Dump truck URAL-63685

The main difference between this dump truck model and others produced at the same enterprise is that it is not the fruit of a conversion, that is, it was originally developed as a civilian, and not a combat vehicle adapted for civilian use. Hence the cabover layout, which is unusual for the Urals.

The fact is that the military mainly takes only “kapotniki”. After all, if a mine goes off under the front wheel of a truck with a hood, then the crew has a much better chance of surviving than in the case of a cabover. But for a civilian vehicle this is completely irrelevant, but better maneuverability and other advantages of the cabin over the engine will come in handy.

The truck was often used for military purposes

Description of the machine

Instead of the old cabin, which first appeared on the Ural-375D model in the early sixties, the URAL-63685 is equipped with a completely new one. It is not the fruit of its own development - this unit is completely borrowed from the Italians from IVECO. There is no talk of any theft, everything is completely legal. After all, at one time IVECO and UralAZ collaborated closely and had a joint venture. But gradually the partnership faded away.

Instead of the “basic” false radiator grille, over time, our own “Ural” one became available for order. However, this option was not in demand, since plastic decor is of very little importance to customers.

The interior is well thought out. Both seats are manufactured by the famous company Pilot. The steering wheel is adjustable, and the rear-view mirrors are heated. And reviews of the Ural 63685 indicate that the standard heater can quickly provide a comfortable temperature, in addition, there is also “autonomy”.

There are also complaints. For example, various buttons with a total of about ten control various on-board systems. Instead of the front panel, these keys were placed on a raised platform on the central panel. Therefore, it is very uncomfortable to reach for them - you have to twist your hand.

Some modifications have a small sleeping area behind the cab. Dump trucks are almost never used for long-distance combat, but the driver can rest normally during the day's break in the shift.

Truck device

Ural-63685 does not have an all-wheel drive system. This is a purely road car with a 6x4 wheel arrangement. However, there are still differential locks, there are three of them. The bridges come from China, they are manufactured by FAW and have performed well even in difficult operating conditions.

There is a protective bar installed on the left and right. Behind it are fuel tanks, batteries and brake cylinders. Behind the car is an underrun beam. It's mandatory now.

Driver's cabin

Brakes

The creators of the Ural 63685 car equipped their brainchild with a working and parking brake system. They are independent and have well-insulated hydraulic circuits. Such a solution allows us to speak about a high level of safety in the operation of the truck, because if the circuit of one of these systems leaks, then this will not affect the operation of the second system in any way. Therefore, for an emergency stop and/or reduction of speed, it will be possible to use the undamaged operating mechanism.

The standard equipment of the brake system, represented by drum mechanisms, includes:

• four spring batteries
• governance mechanisms;
• hydraulic drives and brake pads.

For normal operation of the system, a pressure of 8 kg/cm2 is required.

ADVANTAGES AND DISADVANTAGES

• New European appearance of the car;
• High ground clearance;
• The car is not difficult to operate and repair;
• You can easily purchase various parts and spare parts;
• Relatively low price of a dump truck;
• Powerful power unit;
• Quite a good stove;
• Seat adjustments (driver's seat with air cushion);
• Reliability;
• Practicality;
• Good braking system;
• Large tonnage;
• Good dynamic qualities.

Disadvantages of this plan:

• Not very comfortable seats;
• A lot of free space is simply useless;
• There are questions about the quality and assembly of the interior itself;
• The quality of the materials used is still very low;
• No all-wheel drive;
• There is a lack of comfort inside the cabin.

Cabin

Previously, the Ural Plant actively collaborated with Iveco, and for the Ural 63685 dump truck, the cabin of this manufacturer was borrowed. It is distinguished by a fairly high level of comfort, modern design and European content.

The large windshield provides excellent visibility, and the front optics are protected by grilles from damage by stones. As options, it is possible to install side fairings and a sun visor, which are not included in the basic configuration.

The salon is quite spacious. Inside, all metal surfaces are covered with plastic, and there is fabric drapery on the ceiling. The rearview mirrors can be adjusted electrically. There is also a heating system that prevents them from freezing. The cabin has autonomous heating, which provides a decent level of comfort and guarantees reliable engine starting.

​

Dimensions and weight

Despite the fact that it is positioned as a truck for transporting large tonnage, it has relatively modest overall dimensions:

• length from the front bumper to the rear of the platform, mm – 7,703;
• length from front bumper to rear bumper, mm – 7,404;
• distance between the middle and rear axles, mm – 1,440;
• distance between the front and middle axles, mm – 3,465;
• height from the bottom of the tread to the top of the cabin, mm – 3,148;
• height from the bottom of the tread to the top of the cabin in the tilted position, mm – 3,842.

The load on the front axle is 7,500 kg, on the rear - 26,000 kg. The weight of the fully loaded vehicle is 13,350 kg, with a full rated load - 33,500 kg.

"Ural-63685" can transport cargo whose weight reaches as much as 20,000 kg. If necessary, it is possible to briefly exceed this limit.

Salon and cabin

The salon is quite utilitarian, however, it is not deprived of its advantages. The cabin is quite spacious and has a large glass area. The interior of the Urals is such that it is no longer possible to find uncovered “iron”; everything was closed, and the ceiling was covered with fabric material. The huge rear-view mirrors have an electric drive and a heating system, which is very useful, given that these cars are often used where the temperature drops very low, which increases comfort. To make work in winter more comfortable, and to ensure a confident start of the power unit, the standard equipment of the road dump truck has an autonomous heater system.

The driver's seat has a Pilot air suspension. Moreover, there is a mechanical adjustment of the steering column tilt. There is so much free space that it could be used to place auxiliary glove compartments and drawers for things. However, sadly, there is only one box, which, anyway, looks more decorative than actually practical.

There is a problem with ergonomics. The layout of the dashboard, if you can call it that, was not entirely successful. Although the analogue dials are easy to read, they are placed in a chaotic manner, which is a bit confusing. Similar shortcomings are observed with the switches of the vehicle’s on-board systems, which were placed in a high place between the seats. It seems that a more convenient place for them would be on the front panel, but here they could install, for example, a drawer for things. Generally speaking, the interior of the cabin looks spartan.

Although, when you look at it from the outside, you get the feeling that various changes have also taken place inside. The cabin has a fairly good stove, which in a short time can raise the temperature in the cabin to 18 degrees. All seats located inside can be adjusted in height. In addition to rear-view mirrors, there are also curb mirrors, which will allow you to carry out your work more accurately without possible problems.

Platform

• The platform used to construct the car in question is all-metal.
• That is why with its help you can transport even very large and heavy cargo without any difficulty - the strength of the sides is extremely high, they can withstand very high pressure.
• The tailgate is hinged; if necessary, it can be opened for unloading either automatically or manually.
• The platform has the following technical characteristics:
• loading volume – 12 m3;
• The tilting angle is 50°.

There are modifications from which unloading is carried out not only through the rear side, but also on the sides.

There are special locking mechanisms on each side of the platform. They can be opened either manually or remotely from the cab.

This design is especially convenient when using a truck on a construction site.

The platform is tilted using a hydraulic telescopic cylinder.

For its manufacture, high-strength alloy steel with high density is used. This metal is not subject to corrosion and can easily withstand even extreme loads.

An important advantage of the lifting mechanism used on the Ural-63685 is that it can be controlled from the cabin. This is especially important if work is carried out in bad weather or during rain - the operator does not need to get out of the warm cab to unload.

Wheels

The wheels that the Ural-63685 is equipped with from the factory enable it to move even over difficult terrain without any difficulty. They are disk (8.5-20), equipped with tires of type 12.00 R-20 154/149J.

An important feature of the tires is a very deep, aggressive tread.

It is thanks to it that when the wheels come into contact with any soil, a fairly large friction force arises, preventing slipping.

Also, the deep tread makes it easy to move on icy surfaces without chains or other additional equipment. The wheel formula of "Ural-63685" is 6x4.

Price

The excellent operational and technical characteristics of the Ural 63685 truck make it very in demand and popular. However, the price of a dump truck directly depends on the year of manufacture of the car, the condition of the units, equipment and mileage.

Today, cars manufactured in 2005 are valued at approximately 350 thousand rubles. Models of 2006 cost 100 thousand more, and the price of cars of 2007 starts at 950 thousand.

For a completely new truck in the basic configuration you will have to pay at least 1.85 million rubles, which is quite a bit when compared with its closest competitors.

As for the configuration, the modern Ural 63685 boasts the presence of such options as:

• ICD and MRD;
• PTO and ABS;
• platform heating by exhaust system.

preheater; automatic unloading function; heated and electric side mirrors; sun visor and fairings. Most of these options require additional payment, and therefore their presence automatically increases the cost of the vehicle.

Exterior and interior

The truck received an appearance different from the traditional layout of Ural vehicles. The machine uses a cabin developed by Iveco, mounted above the engine. The abandonment of the hood design made it possible to reduce the length of the car. To improve visibility, a one-piece windshield with 2 cleaning brushes is used. A sun visor is available upon request. To reduce contamination, decorative plastic linings are installed above the wheel arches.

The cabin has a liquid heater connected to the cooling system. Additionally, an autonomous “stove” is installed that supplies heated air to the cabin. Separate seats are installed to accommodate the driver and passenger. A regular sleeping place is equipped behind the backrests. The driver's seat is equipped with pneumatic support and is adjustable in several directions.

The headlights are rectangular in shape and installed in the bumper. On the side of the side members there is a fuel tank, batteries and pneumatic system cylinders. The units are protected by a steel frame, and an underrun guard is installed at the rear.

Wheels

The wheels that the Ural-63685 is equipped with from the factory enable it to move even over difficult terrain without any difficulty. They are disk (8.5-20), equipped with tires of type 12.00 R-20 154/149J.

An important feature of the tires is a very deep, aggressive tread.

It is thanks to it that when the wheels come into contact with any soil, a fairly large friction force arises, preventing slipping.

Also, the deep tread makes it easy to move on icy surfaces without chains or other additional equipment. The wheel formula of "Ural-63685" is 6x4.

Brake systems

The truck in question is equipped with two brake systems:

• parking,
• working

The hydraulic circuits of these systems are isolated, which is why Ural-63685 is considered extremely safe during operation.

Important! If a leak appears in one of the circuits, the second remains operational and can be used to reduce speed and make an emergency stop.

The parking brake system consists of the following main parts:

• spring batteries (4 pcs.);
• brake pads;
• hydraulic drives;
• control mechanisms.

This truck uses a drum type service brake system. It includes a double-circuit pneumatic drive. Part of it is an air preparation unit, as well as an anti-lock braking system.

The pressure required for the normal functioning of the service brake system is 8 kg/cm2.

The brake system requires a minimum of attention: it is enough to carry out a scheduled replacement of brake fluid, pads and other rubbing parts of the mechanisms.

In addition, it is necessary to periodically inspect the hoses and pipes through which the fluid is supplied (especially for front brake mechanisms), since various types of problems and leaks most often arise in this area.
