Operating principle and technical characteristics of the UAZ dump truck

Many people say that a UAZ dump truck is of no use, they say the carrying capacity is not the same, and the box is quite small - it can be loaded and unloaded by hand without any problems. I don’t argue, the eyes are afraid, but the hands do the work. But having loaded and unloaded 5-6 UAZs a day, You’ll already be thinking differently. Now I’ve already put enough work into my hands, especially since the moment of purchase the goal was to make a dump truck, so I’ll start implementing my plans! I don’t know why everyone calls it a subframe - after all, it’s on the frame, which means there will be a subframe. So the subframe was originally I wanted to make it from a bent 120 channel, after all, it is light, and after all, the subframe will twist at least a little together with the frame - I think that the frame on the UAZ should work to twist - this compensates for the very small strokes of the spring suspension - which is very important in off-road conditions. But It was not possible to find a bent channel in our glorious Kurgan, so for production I bought a 100*50 profile pipe with a 3mm wall.

I cut off all the old-style body mounting plates, the area under the subframe turned out to be flat except for the attachment points for the box and another jumper - they are welded overlapping the frame.

These steps were compensated by cutouts in the rubber laid along the entire length of the frame.

The products of the Ulyanovsk Automobile Plant have always been famous for their cross-country ability and wide functionality. The model of this plant - UAZ-452, released back in 1965, gave rise to a whole family of small multifunctional off-road vehicles, including the UAZ-3303 model.

UAZ 3303 Ural rascal › Logbook › Hydraulics

Hi all!
It all happened - I assembled full-fledged hydraulics for the tadpole. Everything is of a classic design: reservoir, pump, hydraulic distributor, cylinder. Everything works great! I'll write everything down in more detail. 1. Pump. Replaced the NSh-10 right rotation www.drive2.ru/l/4517398/. (I’ll get ahead of myself - the pump needs to be changed, because the one loaded with hot oil does not want to unload). It’s comfortable, I can screw on the hoses without any problems. Doesn't interfere with anything. I was most worried that the belt would slip; after all, the pulley on the drive is a B profile. But so far everything is ok. In principle, you can install a short crankshaft-pump belt, then the contact area of ​​the belt will be the floor of the pulley, most likely I will do so.

2. Hydraulic distributor. In the stash there was a tractor hydraulic distributor R-80 with YuMZ-6l.

It has three sections. One for the dump truck, the other two will power the front and rear hydraulic winches (although they don’t exist yet, we’ll come up with them). Initially, I wanted to install the distributor in the cabin, on the tunnel between the gear shift knobs. But he assumed that if something happened, there would be a viper in the cabin in the form of splashed oil. And my ceiling is white...). Then I installed a hydraulic distributor in the tunnel on the cabin side member. To do this, I welded two sections of 20/20 square pipe onto the spar and secured the spreader.

Then I made a cut on top of the cabin and made a power handle from some kind of rod.

3. Tank. I decided earlier on where to mount the tank - on the cab, at the back. After a short search, a 12 liter round tank was found at a scrap metal collection point. I don’t know what unit it comes from. But inside it was a solarium. Didn't wash it much. I cut in a ball valve and welded a fitting for the return line.

4. Lifting cylinder. Initially I was looking for a double-sided cylinder to lift the body. I really wanted a forced lowering of the body. For this purpose, I found (at the same collection point) the working cylinder of the DT-75 blade, and in place with fasteners, which made it easier for me to install it. The cylinder stroke is one meter.

After several fittings (about 15 times), I made fastenings in the subframe and in the base of the body from 100 channels. The cylinder is tilted at 30 degrees.

“UAZ Profi”: truck crane, dump truck, tower and other unusual versions of Ulyanovsk SUVs

This sometimes happens - a car plant invites you to inspect not its products, but the add-ons installed on its cars. The Ulyanovsk Automobile Plant showed a van, a refrigerator, a hydraulic lift, a platform with a hydraulic lift, and even a dump truck. And all this, as well as much more, is based on the UAZ Profi family.

It was almost a fairy-tale plot, but in reverse: hut, hut, stand with your front to the forest and your back to me - I told myself, looking at the line of cars lined up in front not with cabs, but with bodies, vans and all the other installed goods. A sort of review of the basis and superstructures, if you remember historical materialism from your institute days. And there was something to look at - the factory workers showed the entire serial range of add-ons produced on the basis of the “Pro” family. Both our own production and from third-party authors.

An onboard platform with a CMU is one of the trends in the modern commercial automotive industry.
The UAZ Pro family appeared in 2022 and almost immediately showed a good start. Single- and double-row cabs, rear- and all-wheel drive - good potential for expanding the range of add-ons. In addition, UAZ had to move, since the niche of banal tilt LCVs was tightly occupied by another Russian manufacturer of light trucks.

"Tadpole" is a dump truck.
Unloading on three sides will not work for safety reasons. First, about what the plant itself does: flatbed platforms, manufactured goods vans, refrigerators. The big advantage of such machines is that they can be supplied with either a gasoline engine or the ability to run on gas. It is known that gas equipment installed somewhere on the side does not always work correctly, and questions arise with warranty, maintenance, etc.

A promising dump truck on the Profi chassis will hit the market early next year.
A van from UAZ is not just an average box, but an opportunity to choose components during its manufacture. As a standard, the outer frame of the van is surrounded by corners made of aluminum alloy. In “Optimum” this will already be a galvanized semicircular corner with a coating. It's the same with seals. In the standard it is rubber-plastic, in “Comfort” it is polymer. Even the internal volume can vary: 10.8 and 11.3 m3. If a client orders an “Optimum” van, then the warranty period for the superstructure is 4 years or 150 thousand km. Solid. The refrigerator uses a Nizhny Novgorod refrigeration unit.

The bread truck from TTM Center is designed for 112 trays of bakery products.
Trays can be plastic or wooden. Naturally, the plant does not provide its chassis to everyone, but after a comprehensive assessment of the technological and financial potential of the superstructure manufacturer. It just so happens that most of them are located not far from Ulyanovsk, 400 kilometers away.

The location of the gas cylinder is across the frame for flatbed platforms, along the frame for vans.
Perhaps the most interesting car, as well as technically rich, was the auto hydraulic lift from. The base is the five-seater “Pro” version, all-wheel drive. Behind the cabin, on a special subframe, there is a lever-hydraulic installation of the AGP-15 RT lift. Working height - 14.2 m, reach - over 5 m. Electrical insulation of the working platform - 1000 V. Lifting equipment is Italian, the control panel is located on the installation, with dubbing in the basket. The advantages of this arrangement are the minimum space occupied by the machine during operation. The downside is that the lift is cranked, not telescopic. It provides slightly fewer possibilities than the telescopic one - in order to “craw” close to the object, you will have to try. However, machines with such units are convenient not only in dense urban areas, but also anywhere where the work front is not so high.

DIY dump truck UAZ-3303

UAZ-3303 is a small truck with good all-terrain qualities due to the presence of all-wheel drive. It has a frame structure, with a cabin installed on it, under which the engine is located, and two boxes - a transfer case and a gearbox. Behind the cabin there is a cargo hog platform that allows you to transport up to 1200 kg of payload.

This vehicle has become quite popular in agriculture, but its owners complain about the lack of equipment for dump unloading, since the manufacturer of this vehicle does not equip it with such equipment. Owners often do not agree with this decision of the plant and remake the UAZ-3303 with their own hands, creating a dump truck on its basis.

Those owners who have converted their cars indicate a significant increase in functionality and a decrease in the time for unloading the body from cargo. At the same time, the carrying capacity of the car itself does not decrease, since it is not very high anyway. But the installed lifting equipment makes the driver’s life easier, especially if the car is used to transport work loads.

The principle of operation and technical characteristics of the UAZ dump truck - we consider it in detail

The products of the Ulyanovsk Automobile Plant have always been famous for their cross-country ability and wide functionality. The model of this plant - UAZ-452, released back in 1965, gave rise to a whole family of small multifunctional off-road vehicles, including the UAZ-3303 model.

Specifications

The UAZ Profi dump truck has a simple design and ease of operation. This transport is designed to work in any climatic conditions and on any terrain. All the main elements of the car are mounted on a welded support frame, which is made of high-strength steel. This unit can be repaired in the field; all components and mechanisms are easily accessible.

It has an 8-cylinder gasoline engine, manufactured in accordance with the international environmental standard Euro-1, and a manual 5-speed gearbox. Brakes are disc, dry, equipped with a mechanical drive.

Transmission ratios:

The gearbox is equipped with 2 cardan shafts, which are connected to the drive axles of the vehicle. The intermediate shaft is located between the manual transmission and the transfer case. The front and rear axles have a single bevel type final drive with spiral teeth.

Technical characteristics and indicators of the factory truck model:

How to make it yourself

In order to equip a UAZ with a dump truck, it is necessary to prepare drawings.

You can lay a square beam under the front side of the car, attach a long cable to it, which needs to be wound around the entire body part. To unload, you need to open the side of the vehicle, pull out the cable and attach it to some support, for example, a tree or pole. After this, you should start the engine and start moving forward. Moving along the body, the wooden beam will pull the load together.

Another method is to install a hydraulic lifting mechanism, which consists of a half-frame, a hydraulic pump element equipped with an electric drive, a hydraulic crane, an oil tank, a hydraulic cylinder, and high-pressure lines.

Step-by-step instructions for making dumping equipment:

Useful tips

It is recommended to secure one end of the semi-frame with pin hinges on the loading platform, this will help facilitate the operation of the installation. The top of the cross member should be equipped with cross bars to provide support for the entire perimeter of the loading platform.

To connect the semi-frame body to the car, it is necessary to use a welding machine for greater structural reliability.

The hydraulic cylinder can also be taken from the GAZ-53, because it is long enough to tip the body part, and the ends have ball-type tips.

The subframe should be made in the form of a bracket. This shape will allow the hydraulic cylindrical element, when folded, not to interfere with the body tipping over and the installation of the upper part of the semi-frame on the lower one. Parameters and fasteners must be selected experimentally.

After connecting the pumping element lines to the electrical circuit, it is recommended to install hydraulic crane equipment. When the body is raised, it will facilitate the flow of oil fluid in one direction. When the valve turns, the oil will flow back into the tank.

During installation and manufacture of a dump truck installation, safety precautions must be observed. The vehicle must stand on a flat surface, and the wheel mechanisms must be secured with special locking devices. The car needs to be put on handbrake. When making parts, you should wear a protective mask and goggles.

Popular manufacturing options

The UAZ-3303 truck has a two-seater solid metal cabin with two side single-leaf doors. In the front part of the structure, under the removable hood cover, the engine is located. Behind the cabin there is a cargo platform with folding sides. Depending on the model, it is made of wood or metal. The body can transport cargo weighing up to 1200 kg.

Dimensions of UAZ –3303

The technical characteristics of the car are designed for operation in different conditions, including in rural areas. Many people working in the agricultural sector note that despite all the advantages of the truck, it does not have equipment for unloading materials using a dump truck. However, it is possible to solve this problem if you construct a dump truck from an UAZ with your own hands.

Re-equipping a vehicle with a lifting mechanism will increase its functionality and save time on unloading the body. At the same time, the carrying capacity of the vehicle remains at the same level.

There are two options for making a dump truck convenient for use from a UAZ-3303.

Option #1

The easiest way is to lay a square beam under the front side of the body and attach a long cable to it, laid along the entire length of the platform. In this case, the truck will be unloaded as follows:

• When opening the side of the machine, the cable is pulled out and attached to some stable support, for example, a tree or pole.
• As the car moves forward, the beam moves along the body and pulls the load.

This method, although simple, is far from perfect, since the load may end up in an unstable position.

Device for installing springs - drawing

Option No. 2

When constructing a dump truck yourself, a more reliable way is to install the hydraulic system on the platform frame. Despite the fact that some companies offer ready-made kits for lifting the body, you can make such a device yourself.

Step-by-step instruction

The hydraulic lift required for upgrading a UAZ-3303 car with your own hands consists of a supporting semi-frame, a subframe, a hydraulic pump, a control valve, an oil tank, a hydraulic cylinder and an oil system.

Remaking the half frame, hydraulic cylinder and subframe

The semi-frame is necessary to fix the body and change its position. It consists of two parts: the first is firmly attached to the frame of the vehicle, the second to the loading platform. Pin hinges connect the elements to each other. In such a design, it is advisable to use I-beams or T-beams.

The top of the semi-frame is reinforced with a crossbar and side protrusions to support the body; only crossbars are installed at the bottom. At the locations of the pin hinges, special holes are made to ensure reliable fixation of the fasteners.

The half-frame base can also be held together by welding and bolting at the bottom.

Principle of operation

During unloading, the driver must move the crane equipment to a position in which the oil fluid will flow in only one direction. After this, the power to the drive of the pumping mechanism is turned on, which takes part of the oil and transfers it under pressure to the body of the hydraulic cylinder.

When the body part is fully raised, the power to the hydraulic pump drive is turned off. The body will not be lowered thanks to the crane.

In order for the body to lower, the crane must be turned. After this, the oil fluid will begin to flow in the opposite direction, the pressure level in the hydraulic cylinder will begin to drop, and the loading platform, under the pressure of its own weight, will return to its original position.

Operating principle of the design

The installed equipment on a homemade dump truck works like this:

Dump truck from UAZ-3303

• If it is necessary to raise the body, the car owner turns the control valve so that the oil is supplied in one direction.
• After this, the driver turns on the power to the pump drive.
• The pressure pump system supplies working fluid to the hydraulic motor.
• After the body is completely raised, the pump is turned off.
• In this process, an important role is played by the valve, which does not allow oil to flow back, so the body does not fall under its own weight.
• The controlled platform takes its initial position during the return movement of the working fluid, when the pressure in the hydraulic cylinder decreases.

Conversion into a dump truck

The dump truck is fully equipped; you don’t need to purchase anything additional. For installation you will need a grinder and a welding machine.

We send dump trucks to other regions of the TC.

Our company is engaged in the conversion of onboard vehicles of domestic and imported production with a carrying capacity of up to 4 tons into dump trucks.

Unfortunately, the domestic industry does not offer a large selection of light-duty dump trucks, and the price of imported vehicles is very high. The demand for the services of dump trucks of such carrying capacity is growing every year. This is due, first of all, to the development of low-rise construction in Russia, when many people go to live outside the city, and low-tonnage dump trucks are in demand for delivering coal, firewood, humus and other materials.

We offer to professionally and completely legally convert your flatbed vehicle into a dump truck. Work completion time : 7 days

– Low cost of conversion – Registration with the State Traffic Safety Inspectorate – Entering a market where there is no competition – Increasing your income – Increasing the value and liquidity of your car

Modification 330364

In 1997, the Russian light-duty flatbed truck changed its name to UAZ-330364 and also improved its technical characteristics.

In addition to qualitatively new engines, this car differs from its predecessors in a longer wheelbase. She increased by as much as 25 centimeters. Other technical characteristics of the UAZ-3303 modification are as follows:

1. The vehicle's carrying capacity increased by 200-300 kg and amounted to 1,200-1,500 kg.
2. The geometric dimensions of “330364” are 4,535x1,974x2,355 mm.
3. The wheelbase has increased to 2,550 mm.

• The track remains the same – 1,445 mm both front and rear.
• The volume of the fuel tank has increased - 112 liters.
• The installed engines are of two brands – UMZ-4218 and ZMZ-409. These engines show power of 98 and 117 hp. With. respectively.
• The equipment of the braking system has changed - disc brakes were installed on the front wheels, while the rear wheels remained drum brakes.
• The cabin has become more comfortable. Soft adjustable seats are installed. The interior is upholstered and has a plastic instrument panel.
  The steering wheel was replaced with a more comfortable one. Power steering can be installed upon request.

  The cargo platform is made of metal, with folding sides.

  There are two double seats near the front side to accommodate passengers in the back. The platform is lowered by ten centimeters for more convenient loading or unloading.

Recommendations

What is the load capacity? Is COM standard or homemade? Is the PTO installed in the transfer case with NSh-10?

Sorry for the long silence - I was sick. Load capacity 1000 kg. The lump was specially developed (with forced lubrication). Placed on the distributor.

When driving, can you turn it off and then turn it on? Who is installed instead of the top cover of the transfer case?

The elevation angle is too small. What should you do if what you were transporting stuck to the body and won’t slide off?

Cylinder on ball joints Ф50mm. And this is more of a construction option. For peasants there is a slightly different model - with side unloading. For the distributor in the cabin, I can duplicate it with buttons (install an electric valve). But no one has canceled the FSA yet
