Excavator EO-3323 is a universal single-bucket machine used for various earthmoving or construction works. The unit owes its popularity to reliability and ease of maintenance. This tractor belongs to the "long-livers" successfully produced by the Tver Combine since 1983.

General information

Excavator EO-3323 is most often used for digging pits, trenches, loading rocky and frozen soil into a dump. The design of the equipment allows it to be used in urban conditions and in open areas. Serial production of this model has been discontinued, but it continues to be widely used.

Excavator EO-3323 is classified as a single-bucket dredge. The equipment moves on wheels, which simplifies the process of transportation to the workplace. One of the main positive qualities of the tractor is its durability. According to the technical documentation, the unit has a working resource of 8 thousand hours without capitalrepair. The machine can be operated in the most difficult conditions. According to statistics, the equipment is able to work up to 14 thousand hours without serious breakdowns.

Technical characteristics of excavator EO-3323

The following are the main parameters of the modification in question:

• Type of power unit - diesel engine type D-243.
• Power Rating - 81 hp s.
• The pressure in the hydraulic system is 28 MPa.
• Duration of the working cycle - 16 seconds.
• Movement speed - 20 km/h.
• The main working tool is a backhoe with a bucket with a capacity of 0.65 cubic meters.
• Weight with equipment - 12.4 t.
• Dumping height - 5.63 m.
• Frame - welded type.
• Stable platform on pneumatic wheels.

Pros and cons

Among the advantages of the EO-3323 excavator, the following points are noted:

• Operational reliability.
• Comfortable control of attachments.
• Special vibration protection.
• High precision hydraulic equipment.
• The presence of a special sensor that allows you to track the shift in the placement of devices while driving.
• A pair of hinged supports that guarantee complete stability of the equipment during operation, taking into account the large dimensions of the model.

Disadvantages include obsolete design, high fuel consumption, poor operator comfort, no cleaning systemair and air conditioner.

Design features

As standard, the Kalininets EO-3323 excavator is equipped with a diesel power plant located on the right side of the platform. For regions with a mild climate, a D-75P1 configuration motor is mounted with an electric drive, which makes it possible to start the unit directly.

Reinforced hydraulics excavator EO 3323 makes the management as simple as possible. The cabin is equipped with a pair of vertical racks, a conveniently located control panel, and a rounded steering wheel. This configuration ensures that the manipulation is carried out quickly and accurately.

Despite the fact that the engine power is only 75 "horses", the speed limit of the car reaches 20 km/h. Such parameters ensure the transportation of the tractor to the place of work on its own. Advanced modifications are equipped with a reinforced engine with a power of 81 liters. s.

Working Systems

On the EO-3323 excavator, the characteristics of which are given above, in the second generation, an improved design is provided, the elements of which have high productivity with low specific material consumption and increased comfort of the driver's cab.

The car received a significant improvement due to the introduction of updated systems. Hydraulics equipment includes several components and assemblies, namely:

• Hydraulic motors.
• Built-in pump.
• A pair of distributors with four spools.
• Optional one-piece synchronizer.
• Linearand refill filters with a processing level of 25 microns.
• Oil cooler.
• Metered hydraulic type steering.
• Pipelines.
• Reservoir.
• Protection automatic systems.

As a result of the modification of the design, the performance of the hydraulic system has increased, the ultimate pressure has increased to 28 MPa. The performance indicator was 60 liters per minute. Such parameters are considered high-performance for that period. All of these points have reduced the weight of the machine.

Chassis

The excavator under consideration is placed on a full-revolving platform with pneumatic wheels. The base has an elongated boom with a handle, which is connected to the working body. The platform rotates with the help of a hydraulic drive and a two-mode planetary gearbox.

The chassis is a welded metal structure with a 4x4 wheel formula. The front part of the front axle is controlled, two retractable supports are installed on the chassis. A bulldozer blade is placed in front, acting as the third support, the design of the machine allows it to be transported at a speed of 50 km / h.

Mounted and main equipment

Excavator standard attachments include a backhoe and a monobloc L-boom The main mechanisms are made of low alloy steel and are highly resistant to corrosion and wear.

Characteristicsstraight shovel:

• The cutting rate of the soil is 100 kN.
• Maximum digging radius/height - 6780/7660 mm.
• Unloading - 4200 mm.
• Ground cutting force (maximum) - 100 kN.
• Maximum processing depth - 5400 mm.
• Bucket capacity - from 0.5 to 0.8 cubic meters.

Among the additional accessories, the tractor can be equipped with an arrow stick of various lengths from 1900 to 3400 millimeters, a direct loading bucket with a capacity of 1.2 "cubes", which allows handling cargo with a density of up to 1.4 tons / cubic meters. m.

Other equipment:

• Hydraulic breaker with interchangeable tips.
• Ripper for frozen soils.
• Tamper plate.
• Auger and drilling equipment.
• Load lifting devices.

Cab

The workplace of the equipment in question is one of the most important elements of equipment. According to the new standards, it must comply with certain rules and requirements. The cab configuration features a rigid frame with increased torsion resistance. A pair of vertical posts act as fixing parts.

The driver's seat is adjustable horizontally and vertically, equipped with shock-absorbing system and seat belt. Rear-view mirrors are mounted outside the cab, analogues are additionally provided for fixing "dead" zones. Comfort is enhanced by a heater, modern control devices, sun visors, windshield wipers. Also availabletwo server consoles.

Dimensions and purpose

Key sizes:

• The weight of the excavator EO 3323 is 14 tons.
• Length/width/height - 7, 55/2, 5/3, 7 m.
• Destination - loading and unloading of bulk materials.
• Digging trenches, canals, pits, including soils of the fourth category.
• Quarrying and frozen soils.
• Building applications.

Summary

In 1983, the Kalinin excavator plant produced a completely new machine for that period. Universal single-bucket equipment was distinguished by the presence of a pneumatic wheel travel and a number of enhanced characteristics. The last manufacturer of this excavator was TVEKS Corporation. The unit is still actively used in various economic, mining and construction sectors.
