Amkodor front loader, tractor characteristics

Purpose

The front-end loader Amkodor-342V has a fairly broad purpose, namely, it is capable of performing the necessary tasks of industry, construction, enterprises, as well as public utilities.

In the construction of any objects or in the process of laying roads, it is used for leveling work sites, creating embankments, loading loose and lump soil, as well as transporting it over short distances.

Also, by equipping the machine with special equipment, it is possible to lift any loads whose weight does not exceed 4000 kilograms. With a basic bucket, the equipment is capable of performing various earthmoving-type works (digging trenches and foundation pits).

Without loosening, the loader is able to cope with soil of the first, second and third density categories, when the fourth category is available after loosening.

Enterprises and industries also use this machine for loading and moving bulk and lump materials. In addition, Amkodor loads various pallet cargo. A crane boom can also be used for lifting.

Utilities, as a rule, use this machine to clear highways, streets and many other areas (including the courtyards of large organizations) from large snow masses. In this case, the loader can use both standard front-end equipment and special additional equipment designed exclusively for cleaning.

KUHN loader

The Russian company produces the KUN-10 AND KUN-08 front loader. It was founded in 1934 on the basis of the Gigant state farm, when the central workshop was reorganized into an automobile repair plant. After the war, production was concentrated only on the production of machine tools. Since 1960, the orientation has completely changed to agricultural products. But already in 1973, the production of the famous KUN-10 began, which, through modifications and changing chassis, has reached the present day and continues to remain in service.

Now the KUHN 10 front loader is a mounted loader boom that can be installed on modern tractors with its own hydraulic system.

The manufacturer offers the sale of the unit both with the tractor and separately, which will help to save significantly if the customer has suitable equipment. Photo of KUN-10 loader

This loader can also be used as an excavator, bulldozer, and leveler. However, quite often several more units are attached to the tractor, which allows the loader to be used entirely for its intended purpose with maximum efficiency.

Advantages of KUN-10:

• Can be used as an attachment for a wide range of tractors;
• The manufacturer offers a wide range of replaceable working parts for front loaders;
• More than 50 years of operation of this unit have proven its high technical characteristics, as well as reliability.

Specifications

Equipment of such dimensions is not always maneuverable, which limits its scope of application. But for Amkodor 342V this is not a problem, because The turning radius in small spaces is 6 m.

The machine's lifting capacity is 4 tons, the standard bucket holds 2 or 3 m3 of lump or bulk materials. The power of the equipment is determined by the breaking force, in this case it is 12 tons.

Parameter Meaning

Dimensions Amkodor 342V:

• length - 7.5 m (including the length of the bucket),
• height - 3.45 m,
• width – 2.5 m.

The main characteristics of Amkodor 342V are:

• bucket edge length – 2.5 m;
• lifting height of the bucket during unloading – 3.1 m;
• tipping load – 120 kN.

Thanks to such indicators and technological features of the equipment (the cutting edge is quite long and quite sharp), the loader can operate with clay and stone materials. Combined with the breaking force, even in such conditions, the equipment has high productivity.

The vehicle speed is 6.6-37 km/h, which is provided by a four-speed gearbox.

The weight of the entire structure is 11.5 tons, of which the front axle weighs 4.75 tons, and the rear axle weighs 6.75 tons.

Engine

The D-260.1 model runs on diesel fuel. This is a four-stroke six-row power plant equipped with gas turbine supercharging. Cooling of the unit occurs passively and using a coolant-liquid.

Parameter Meaning

The system has high pressure, so high-strength materials for the engine were selected. The unit is intended to be used under severe operating conditions (including temperature changes or extreme values), so its service life is quite impressive.

Characteristics of the D-260.1 engine:

Absolutely any engine has its own characteristics, the most interesting being the volume of the unit. For D-260.1 it is 7.12 liters, and its rotation speed is 2100 rpm.

Next, you should pay attention to the engine power – 155 horsepower, as well as the maximum torque – 622 Nm. An important indicator of the quality and performance of the engine is the cylinder diameter, which is 11 cm.

Additional information includes weight with capacitive elements - 0.7 tons and compression ratio - 16.

Fuel consumption

An important feature of the loader can be considered low fuel consumption, despite the presence of a very powerful engine. The reasons for this are:

• hydromechanical transmission;
• gas turbine supercharging.

The hydromechanical transmission minimizes power loss, which is why all fuel is used with maximum efficiency.

Gas turbine supercharging also increases engine power by increasing efficiency, without increasing consumption.

Amkodor-342V has many advantages that make it extremely popular in construction and other work related to transportation and loading.

Most dealers sell this equipment for no more than 2.3 million rubles.

Design

Compact and powerful, the loader features a Z-type linkage system that provides excellent functionality during earthmoving and quarrying operations. The lifting height of the bucket is more than three meters, and the reach of its edge is about a meter. The six-meter turning radius is an excellent indicator. The twelve-ton breaking force is also impressive.

The frame that controls the steering wheel moves using a hydraulic drive and hydraulic feedback. Hydraulics - two-pump, with a two-spool hydraulic distributor. The loading equipment has one hydraulic cylinder that controls the rotation of the bucket.

After unloading is completed, the kinematics of the working mechanisms lowers the bucket down.

The diesel engine has a power of 155 horsepower. The fuel consumption of the loader is quite economical - this is achieved by the hydromechanical volumetric transmission.

The hydraulic tank holds 110 liters of fuel, the fuel tank – 215 liters. The formula for determining fuel consumption looks like this:

P=0.7xRxN (units of measurement - kg/hour).

Here R (measured in gkW/hour) is an indicator of specific fuel consumption, N (measured in horsepower) is engine power.

Transmission and chassis, steering

"Amkodor-342V" is equipped with a reliable gearbox. Her work has its own specifics. For forward movement there are as many as four speeds:

• speed in first gear – 6.6 km/h;
• speed in second gear – 12.2 km/h;
• speed in third gear – 22.6 km/h;
• speed in fourth gear is 37 km/h.

Reverse movement is also possible at first and second speeds:

• first gear – 6.9 km/h;
• second gear – 22.3 km/h.

The design includes a limited slip differential. Its presence allows you to move over rough terrain, and even heavy dirt will not become a serious obstacle for the loader.

It is this, as well as the aggressive and very deep tread, which allows the wheels to easily cling even to liquid mud, that is the secret of its good cross-country ability.

The transmission is hydromechanical. It regulates engine torque automatically. Special sensors send corresponding signals to the control unit, which regulates the fuel supply.

Control is carried out using a hydraulic booster. The hydraulic system of the loader is equipped with a special priority valve. It is he who makes operating the equipment simple and easy.

The steering mechanism consists of the following main components:

• articulated frame;
• hydraulic drive with feedback;
• emergency pump.

The wheels are steel rims with standard 21.3-24 (530R610) rubber tractor tires. At the factory, the loader is equipped with reliable tires from well-established manufacturers (Continental and others like them).

Braking and parking systems

The braking system is typical for this type of equipment. It consists of discs located in wheel hubs.

There is an oil bath inside the hubs, which increases the service life of the brake mechanisms. It quickly removes heat from the rubbing parts of the brake system.

The brakes are operated by a special hydraulic drive. It is separate, each bridge is equipped with its own drive device.

The design has a parking brake - single disc, dry. It is driven by a mechanical drive, which is a rigid spring connected to a lever in the cabin by a steel cable.

The release of the brakes is carried out using a hydraulic drive. It is very difficult to do this manually.

Refill tanks

The operation of the main bucket is always carried out in accordance with the hydraulic cycles:

• bucket lifting time – 5.6 seconds;
• unloading time, tipping – 1.2 seconds;
• lowering the bucket – 3.3 sec.

It is thanks to this speed of operation that Amkodor-342V is extremely productive. It is positioned as commercial equipment (professional).

Initially, this model was designed for use on construction sites, in quarries and other similar places where it is very important to perform a large amount of work in a short period of time.

The fuel tank can simultaneously hold about 215 liters. This reserve makes it possible to save a lot of time by not having to refuel frequently.

The hydraulic system also requires a fairly large amount of special fluid - as much as 110 liters.

Device

The Amkodor 342B front loader has increased maneuverability due to the deep tread on the wheels, which are made of steel wheels and rubber tires. This allows the loader to move over any type of terrain without wasting time. The limited slip differential has the same effect.

The fuel supply depends on the signals received by the control unit. And the hydromechanical transmission automatically regulates engine torque.

The equipment is controlled by means of an emergency pump, an articulated frame and a hydraulic drive, the signal to which is received from the operator through special devices.

The operator's cabin of the Amkodor 342B loader, although small in size, is functional and comfortable. The ergonomic arrangement of controls and an adjustable seat to suit the individual characteristics of the person allows the operator not to be overloaded during work.

Lighting devices in the cab are installed to allow work to be carried out in the dark, and rear-view mirrors ensure the safety of work. Regardless of the season, the cabin microclimate can always be adjusted so that the operator feels comfortable. This is ensured by the presence of a heating and ventilation system.

Safety systems of international standards make it possible to limit the operator from emergency situations and health risks.

The Amkodor 342B drum brake system is an everyday solution for front loaders. The hydraulic drive allows you to stop the car smoothly and comfortably, and it can operate the axles separately. The parking brake is a dry single-disc brake that operates mechanically, without a hydraulic drive. In this case, the brake release is performed using hydraulics.

Driver's cabin

The driver's cabin of the loader is distinguished by its modest overall dimensions. Despite this, being in it is quite comfortable. This is possible due to the thoughtful placement of the driver's seat, as well as all controls.

If necessary, it can be very easily adjusted in height. Therefore, any driver, regardless of height, can comfortably operate the equipment in question.

The cabin has a large number of various lighting fixtures, allowing you to work even in the dark. Rear view mirrors have a wide viewing angle, capturing everything that happens behind the driver.

Attachments

The most popular models of mounted functional organs are:

• various dumps for snow removal, excavation work, etc.;
• loading forks for work in warehouses or in agriculture;
• extended boom for working with limited access equipment;
• The hay thrower is used for stacking hay or straw in agriculture;
• “paw” gripper for transporting folded flat loads;
• jaw gripper is primarily used for transporting pipes, logs and similar elements;
• buckets with a volume of 1.5, 2.3, 3 m3 to increase productivity during work;
• crane boom (truck crane principle).

Engine power does not affect fuel consumption, so the model is economical with high performance. This effect is achieved by installing a gas turbine supercharging and hydraulic drive. This and other advantages led the model to increased demand, and the manufacturer received greater profits.

Design Features

It is a boomerang-shaped boom, which is controlled by 4 hydraulic cylinders - two of them are used to lift the boom itself, and the rest directly control the tilt of the bucket. The entire system receives its power from the common hydraulic system of the chassis on which it is installed. The universal mount allows the use of a variety of replacement equipment. At the same time, control remains the same and is carried out from the chassis cab.

In addition to the KUN-10 loader, the plant also produces the KUN-08, which differs from the base model only in the bucket capacity.

Front loader diagram KUN-08

The manufacturer proposes to install the following replacement equipment:

• Buckets of various capacities, which can range from 0.35 square meters to 1.5 m3.

As the power increases, the maximum load on the bucket also changes, so larger ones are suitable only for working with light loads with a specific gravity of up to 5 kN/m2, which is suitable, for example, for sawdust, but the smallest one can cope even with a specific gravity of 15-25 kN/m3 and is perfect for sand, crushed stone or fertilizer.

• Fork for loading manure, silage and so on;
• Forklift equipment for handling cargo on pallets;
• Rake grid for transporting hay to various distances;
• Log grabber for logging operations, as well as simply for transporting logs;
• Fork device, as well as gripper for loading and transporting bales and rolls;
• Jaw blade, which can simultaneously serve as a bulldozer blade and a bucket for working with light, loose materials.

Advantages and disadvantages

The positive characteristics of the Belarusian forklift are:

• high performance;
• good maneuverability;
• excellent maneuverability;
• small sizes;
• decent operational reliability;
• simple controls;
• moderate fuel consumption;
• comfortable and safe operator’s workplace;
• affordable price.

If we consider the negative aspects of the machine, then it is necessary to dwell on the following points: a weak hydraulic system, lack of quality service and difficulties with the supply of spare parts.
