Excavator Tatra UDS 114: technical characteristics, model features, analogues

Excavator purpose

This car is special. Truck crane and earth mover in one. A successful solution was to place the excavator unit on a vehicle base, in this case a Tatra. These excavators began to be produced more than 20 years ago in Slovakia. The result was mobile, powerful special equipment. The Tatra planner excavator can make embankments up to 15 meters high. Due to the fact that the unit is located on the machine, it arrives at the work site under its own power at high speed. Can work on steep slopes. Where other technology cannot work. The UDS 114 excavator is more powerful than a conventional construction excavator. A platform with a boom or bucket (replaceable equipment) can be installed on other machines, not only on Tatra - on Kamaz, MAZ, Ural.

It is used in road construction in preparation for laying roads. Levels the soil before adding crushed stone. It is used to improve the terrain before building bridges. Works exactly. Where it is necessary to deeply open the soil with already laid communications. To avoid touching the pipelines, this excavator is used. It can dig deep pits and trenches at an angle of 90%. It has proven itself well in the Far North and can work in permafrost conditions.

Excavator-planner Tatra UDS

The technical characteristics of the Tatra UDS 114 are such that this machine has found application not only in construction. Works in the oil and gas industry, geological exploration and other places where work is needed in hard-to-reach places. Can be used as a forklift and stacker. Its analogues are the Belarusian excavators “ANTEY” and “SVYATOVIT”.

Purchase of excavator UDS-411

Today, you can buy Tatra UDS-114 only on the secondary market, since the TATRA 815 model has been officially discontinued for a long time. However, in terms of spare parts, the situation is quite stable; the manufacturer systematically sells many repair kits and spare parts all over the world. During the purchase, you need to pay attention to all the main components for the car: engine, transmission, chassis, suspension, condition of the body and frame. Very often, this special equipment exhibits curvature of the supporting structure, which can be easily detected by placing the vehicle on a flat surface.

TATRA 815 chassis distinctive qualities

The Tatra 815 UDS-114 was equipped with several types of pneumatic-wheeled chassis, with 4x4, 6x6 and 12x12 drive. The most common are smooth, road tires, which are mounted with metal wheels on a base with 2 drive axles. The peculiarity of the suspension is that it is equipped with special air springs and transverse stabilizers, thanks to which it was possible to achieve high cross-country ability and stability during various works. The reliability of the chassis allows the vehicle to be used without repair for 250 thousand km, depending on the weight of the cargo being transported.

Repair options

The highly efficient Ttatra UDS-114 excavator, which has a relatively low price, is capable of performing various types of repair work. Thanks to the leveling excavator, it is possible to construct road embankments for further laying of asphalt pavement, laying a base of crushed stone, developing pits, as well as cutting off old asphalt. In road construction, a road milling machine at MTZ is also indispensable. TATRA 815 is also used for public works, when penetration into hard-to-reach areas is required without compromising the integrity of highways.

General technical specifications

The all-wheel drive planer excavator Tatra UDS 114 weighs 22 tons 300 kg. Has the following parameters:

digs to a depth of 6 meters 60 cm;
develops slopes up to a height of 7 meters 70 cm;
treats the soil around itself with a diameter of up to 10 meters;
digging force – 85 Kn.;
has two drive axles, rear wheels are paired;
can produce soil 108 m3/h;
two fuel tanks hold 400 kg. diesel fuel.

When working as a crane with the boom extended to maximum, it lifts a maximum weight of 2,600 kg. When the boom reaches its minimum, it lifts 7 tons. Excavator attachments have many functions and are therefore varied. These are all kinds of knives, buckets (with and without teeth), pliers, grippers, grabs, asphalt cutters, arrows of different sections, hydraulic hammers and mowers. Diesel fuel consumption during operation of a tower (crane, excavator, etc.) is 10 liters per hour.

Engine characteristics

The excavator platform has a John Deere 4045 HF 275 motor, its parameters:

4 cylinders;
holds 4.5 liters of diesel fuel;
rotates 2000 rpm;
has a voltage of 24 V;

The diesel platform in question operates separately from the machine on which it is installed.

Advantages and disadvantages

Now the Tatra UDS 114 has not been produced for a long time. Instead, UDS 214 are produced. But there are still a lot of spare parts for the old modification of the car. In addition, the manufacturing plant continues to produce spare parts and provides countries operating the machines with new spare parts.

There are also disadvantages . Often the structure of this car becomes bent due to difficult working conditions. This is easy to detect; you just need to look closely at the car standing on a flat surface. If there is one, then, after straightening the structure, you need to strengthen the frame with additional rods, weld additional cross members and corners. Another drawback: when moving, during hauls, a lot of fuel is spent - 40 liters per 100 km. But with everything else, the technical characteristics of the Tatra 815 UDS 114 greatly distinguish the car from other diesel engines in its power and mobility.

Excavator device

The excavator platform can be installed on any powerful vehicle. Initially installed on the Slovak Tatra car. A platform that, together with attached working equipment, rotates 360 degrees. Thanks to this, the excavator gained popularity among road workers and representatives of other industrial professions. The power of the excavator is provided by a power unit with hydraulic drives and other working units. There is a special hydraulic tank that holds 150 liters of oil.

The driver's cabin is spacious, comfortable for work, and has air conditioning and ventilation. The machine has a boom driven by two powerful hydraulic pumps located on the sides below.

Tatra UDS 114 trucks have a high-power propulsion unit. The first production of cars had 3 drive axles. Subsequently we moved to 2 bridges. The car has a 6-cylinder diesel unit with a capacity of 12.7 liters. diesel fuel. The car was equipped with smooth wheels. There is no rear heating, since the car was originally prepared as a base for a crane and excavator. In the northern versions of the vehicle, the design provided for additional heating of the diesel engine, the vehicle cabin, and the driver’s cabin.

UDS-114 on TATRA chassis features

The universal installation UDS-114 based on the Tatra vehicle is a special excavator-type structure, which is attached to the load-bearing frame of the truck using a welded metal frame. At the same time, the car frame is necessarily strengthened in all main places where the maximum load is observed. Most often, the frame has transverse struts that are welded directly into the supporting frame itself. Thanks to the spacers, the excavator does not deform the vehicle base during its work. UDS-114 has a rotating telescopic boom, which is driven by powerful hydraulic cylinders located under the main frame and inside the boom. This installation based on a TATRA vehicle has great potential for performing a different range of work, in particular, the equipment can be used as an excavator or a crane. The special design of the boom allows the excavator to develop pits at 90 degrees, as well as to undermine the soil under already installed communications, facilitating the work of technical personnel. The equipment has much greater capabilities than a conventional construction excavator.

Technical component

Tatra UDS-114 trucks are equipped with an increased power engine, as well as high-performance hydraulic pumps. In its model range, the TATRA 815 initially occupied the place of off-road trucks. The first cars were produced with all-wheel drive and 3 drive axles, but in the latest versions the developers limited the number of drive axles to 2. UDS-114 units are most often mounted on city cars that have a chassis with smooth tires. Under the hood of the truck is a 320-horsepower six-cylinder diesel unit (some versions had engines of about 500 hp) with a volume of 12.7 liters. Very often, cars of this brand were equipped with a “northern package”, which included an additional heating system for the engine, cabin and body. Versions with a crane installation do not have a body, so they are deprived of rear heating in advance. The machines have proven themselves to be excellent in domestic operating conditions, just like wheeled excavators.

Performance characteristics

The technical characteristics of the Tatra UDS-114 truck, which still allow it to carry out many complex excavation works, has good performance in terms of operation in different climatic conditions.

Features of operation

The unique Tatra UDS-114 equipment is used to develop different types of soil, including in permafrost conditions. Installation with the vehicle during operation is quite unpretentious, but periodically it is recommended to check the main working components, in particular hydraulic supports, boom hydraulic cylinders, turntable mount, chassis drive, condition of the engine and hydraulic pump. Thanks to the pneumatic wheels, the leveling excavator has the ability to be quickly transported to any construction site.

Reviews

The car has proven itself on the most positive side. Drivers speak very highly of it. The planner can drive onto any slope. Stops. The operator of the rotating tower with attachments extends the supports. Fastens. Starts working. Hence the name - planner. Sets the terrain plan. And if something is wrong, he corrects it. Few units can have so many options for attachments. It is for this multifaceted versatility that people value this car and dream of purchasing it. When acquired, they treasure it like a treasure. Because this one machine replaces a dozen others.

For clarity, as an excavator it processes the soil both below and above with the same speed and force. Down - 7 meters, up the same 7. Changing a bucket with teeth to a toothless one allows you to adapt to the ground. Depending, in some places the soil is loose and in others it is hard. Hour after hour, the machine changes the environment around itself. Changing your location from time to time. These excavators rarely break down.

Guys, I will sell the UDS-114 unit inexpensively in St. Petersburg. I wanted to keep it for myself, but I need money... It is already without a chassis - I sold the Tatra, but the UDSku can be installed on any chassis (Maz, Kraz, Kamaz), it is completely autonomous, with with your engine...

you can move without sitting in the cabin and turn around, you just raise your paws, of course the handbrake should not be on and then you either push off with a bucket or pull yourself up or lift yourself up on the bucket and turn around one trench around the oil pipe (to install a patch) we have a table 3 years ago 5000 rubles then a person who did this sold the Tatra and bought a trawl with a caterpillar excavator, it transports itself and the tracks have better cross-country ability, so you won’t regret taking it

My friends, I have these units in my garage, left over from my father, he is gone now, and I still don’t know what they are. The only thing I know is that it’s from a Tatra car, maybe someone knows what it’s called correctly, or maybe someone needs it. Suddenly someone is looking for something and can’t find it, but it’s just taking up space for me.

In the third photo is the NSh Tatrovsky that is on the box, in the other photos there are spare parts from the installations

for posting on the mixer topic

Max would pay how much for it!? So that you don’t mind!? I would put it on the shelf as a reserve, maybe it will come in handy.

Georgy, why did the topic fade away?

Hello, Sergey! They dissuaded me, probably envious people :))) I dialed after the manipulators, plus I started building a house, it seemed like I was busy with something, and the thought was lost. Now my thoughts are again tormenting me: should I buy another all-terrain vehicle or should I throw all my energy into decorating the house?

The topic is old and may not be relevant, but I’ll get in.

There is only one company, a huge one, a road company, which until recently was widely used. In short, gradually, as they became worn out, they were written off. Until recently there were 5-6 pieces. Many people I heard talked about the stupidity of using them in our conditions. The only place where they are very good is on the slopes of roads. And then. If you have black soil, then an excavator will do much more. And you won’t find a decent excavator driver. Everywhere they were abandoned and wheelers switched to full turns. They are more versatile and less fragile, unpretentious to the conditions.

Regarding the relocation, I haven’t heard either, but on the contrary, that all control is from a birdhouse.

Here. From 01-55. watch further.

In the summer, the car's engine hit 370 thousand kilometers, we bought a new knee for 0.5 rubles.

You're probably right, in our layout near the road it's easier to use a large trawl for a large volume.
