As showing the reviews of the owners, the technique pays off pretty quickly. You can repair it almost in any service center. Among the disadvantages - the impossibility of the operation of the machine on weakly infant soils due to the characteristics of the wheel formula.

Officon and storage

Before commissioning a new excavator, it must be carried out its runoff. It lasts at least 30 hours. If you subjected the car at once with maximum loads, this will certainly lead to a premature deterioration in the technical condition of the equipment or excessive wear of the details. Nodes and mechanisms designed for certain temporary assembly of the unit should also roll up.

Immediately after running, a technical inspection of the excavator is carried out. This includes:

• checking cleanliness and oil level in turning mechanisms;
• pay attention to the condition of all fasteners and bolted compounds;
• change the filtering elements in the hydrorestervoire;
• remove and clean suction filters.

For long-term storage, the excavator is prepared in a special way. Follow the hydraulicum of the working fluid, the breather is wrapped with oiled paper. The fuel tank is fill in flammable with anti-corrosion additives. Machine washed, wipe dry, traces of rust clean up and tinted. Store equipment is recommended in a dry closed room or on special sites under a canopy.

On the video capabilities of the excavator TVex EK-18:

Single-line wheeled full-turn excavator EK-18 is a high-performance earthmoving specialist. It is used on the development of catlings, digging trenches in the ground of any category, from the first to fourth. EK-18 produces loading and unloading of cargo, loose rocks, bulk cargo. Apply this excavator and for the destruction / disassembly of old brick and reinforced concrete structures of high strength.

The manufacturer's enterprise determines temperature Rangein which the EK-18 excavator retains its performance as "from -40 to +40 degrees Celsius." The scope of application of this technique is expanding using a variety of replaceable work equipment. For a special order, this excavator can be equipped with a Bosch-Rexroth hydraulic approacher (hydraulic distributor, hydromotors, pumping unit and control blocks).

Currently, the manufacturer of the EK-18 - Tver Excavator Plant (TVEC) is part of the company "RM-Tereks", one of the leading machine-building in Russia. It specializes in building and road machinery and unites 4 plants: Tver Excavator, "Bryansk Arsenal", Chelyabinsk Plant of Construction and Road Machines and Zavolzhsky - Crawler Tractors.

Through 78. dealer centers In Russia and the CIS, "RM-Tereks" sells, serves and provides spare parts: Excavators-loaders, wheel and tracked excavators, automotive traders, tracked snow-banners, frontal and forklift, industrial overloaders. All manufactured equipment has the official status of "Made in Russia".

Tver Excavator Plant (during the USSR, he was called "Kalininsky", like the city itself) leads its history since 1943. Still before the final victory in the Great Patriotic War in Kalinin, the construction of a plant for the production of spare parts and components for excavators, saw shafts, multi-storey lifts, other peaceful techniques and consumer goods has begun.

Soon after the end of the war, the enterprise began the release of the first excavators in the country at a pneumopole move with a cable suspension (model E-255). In the 197th year, the plant mastered the production of hydraulic wheels and tracked excavators. In 1978, one of these models - EO-3322B was assigned a state-quality mark of quality. In March 1981, a fifty-year-old excavator came from the enterprise conveyor, and the plant for replenishing the national economy reliable and productive equipment was awarded the Order of the Red Banner of the Labor Banner.

Engines TVECs traditionally use Minsk. Most of the other nodes, aggregates and components of excavators are produced directly on Tver Excavator, even in our time. According to statistics, more than 90% of Specmashin manufactured at the factory are equipped with domestic production hydraulics and Belarusian diesel engines, and only about eight percent are manufactured with Bosch-Rexroth hydraulics and imported PERKINS engines.

Design and device excavator

The wheel excavator EK-18 from the following main component parts and SICTEM:

• pneumocole chassis,
• swivel platform
• hydraulic system,
• pneumorization system,
• electrical equipment
• working equipment.

The pneumatic society of the special machine is made on 2 leading bridges. It can provide a sufficiently high speed of movement on the workplace and on the roads between them, as well as, if necessary, a simple and safe towing of EK-18 tractor.

Managed is the front axle. Tires on it single; The bridge itself is balancing on the chassis. The rear axle is uncontrollable, double; Fastened to the chassis rumble. The drive of the bridges is made through the gear change box and cardan shafts, from a low hydromotor. Before earthworks, the excavator relies, to increase sustainability, on folding supports and support-dump.

The swivel platform is attached to the reverse tilt device, which is mounted on the chassis. On the Rotary Platform are fixed: force aggregate and a tank for diesel fuel, turning mechanism, operator cabin, installation of heating and ventilation, hydraulic equipment (Hydrobac, hydrocrators, oil cooler installation, etc.), elements of electrical and pneumatic equipment, as well as counterweight.

The EK-18 excavator operating equipment is installed in the tears of the rotary platform and secured with the help of fingers. The design of this specialist provides for the possibility of applying all kinds of replacement work equipment and working bodies. In addition to the reverse shovel, it is a grab, hydraulic hammer, ripper, hydronomy, logs, etc.

Additionally, the technological capabilities of EK-18 expands, increasing the degree of universality of this special equipment, frontal dump-support. They can fall asleep trenches, clean the surface of the soil, raking the steering garbage, to plan the working platform.

Drive of all movements by replaceable work equipment, as well as the management of the excavator and its executive bodies steering - hydraulic. Controlling brakes of wheels and parking brake, gear shift is pneumatic. EK-18 equipped with electrical systems Lighting, ventilation, alarm and dyel start, and ready to work at any time of the day and at any climate, while maintaining normal conditions for working in the cockpit.

In the composition of the EK-18 undercoming device: chassis with a reference device; folding supports + support-dump; Transmission Change Box, Front and Rear Bridges, which are connected cardanian treals; The turning mechanism of wheels and management of them; The central collector, which is connected by pipelines with a hydraulic drive of transmissions, reservoir hydraulic cylinders and hydraulic cylinders of dump support, as well as with components of a pneumatic control system: built-in air intended pecification, brakes of wheels, parking brake, gear mechanism.

The reverse rotary device on the excavators of this model is the rotary support of the bearing type: roller, single-row, with internal engagement teeth. The platform is rotated by means of a low-negle axial-piston hydraulic motor with a 2-speed planetary gearbox. It increases torque and reduces the frequency of rotation of the rotary platform.

The transmission (gearbox) of EK-18 is used to transmit torque from the hydraulic motor to the leading bridges; To switch gear, turn on / off front Bridge and preventing the spontaneous start of the movement of the excavator (use of the parking brake). As part of the flush changes - hydromotor, 2x-speed gear, gear shift mechanism, parking brake. In the excavator bridges, pneumatic brakes of the brake type are mounted.

Parking brake EK-18 is a constant-closed look, with pneumochlectric control. Gearing can only be performed after the excavator stops complete. The pneumatic system of specialists participates in brakes, in switching gearbox, in turning on / off the front axle.

Bridges

As part rear bridge Excavator of this model - main gear, Kaptep, hubs of wheels with details stretched in them (planetary transmission, semi-axis, bearings).

When EK-18 moves straight, on a flat road, the leading wheels on the right and on the left pass equal paths. When turning, as well as when driving on the uneven surface of the soil, the leading wheels of the excavator, which move along the inner radius and experience great resistance, rotate slower than wheels, which move along an external radius and are experiencing less resistance.

The mechanism of completing the turn of the wheels consists of a system of Phachgigs, ppodol and padded thrust, which ensure the rotation of specialists both in self-ride and when it is towed by tractor.

The absolute majority of excavators of this model are equipped with diesel engines of the Minsk Motor Plant. In the modification EK-18-20, this is MMZ D-245C, 105 horsepower (at 2200 rpm) and a maximum torque of 384 N.M. (at 1400 rpm). In the modification of EK-18-20 -MMM D-245.2S2, which develops capacity122 horsepower, at 2200 rpm and 501 N.m of the torque (at 1600 rpm).
