Cylinders of the domestic engine with a diameter of 110 mm are arranged vertically in a single row. The main components of the engine are connecting rods, pistons, cylinder block, cylinder head, flywheel, and crankshaft. All of these are serviced. A turbocharger is used to increase the powerplant’s output, increasing torque to its maximum value (386 Nm) and throttle response. The supercharger force is adjustable by the operator.
To start the engine in cold weather the German-made starting heater “Hydronic 10” is available.
Fuel consumption of EK-18 is 236 g/kW per hour of operation, and the diesel fuel tank has a capacity of 255 liters.
chassis
The undercarriage is represented by a wheeled chassis. The excavator is equipped with a hydrostatic transmission from German company ZF, which features high reliability, long service life, and efficiency in all working conditions. This transmission in combination with the engine allows the car to move at the speed of up to 20 km/h.
Movement of the TVEKS 18 excavator at the construction site is autonomous. To transport the equipment to the construction site it is necessary to use a tractor, with a maximum speed of 40 km/h.
The standard equipment includes a blade support and two outriggers, which give the machine stability.
hydraulic system
Customers have an opportunity to buy TVEKS EK-18 with different hydraulic systems, depending on the modification of the machine. Russian company Pnevmostroymashina is installed by default. It is characterized by power of 50 kW or 70 hp. The maximum pressure in the system is 28 MPa, and the pump that creates it pumps 248 liters of hydraulic fluid per minute. The hydraulic fluid tank has a capacity of 350 liters.
The versions are equipped with a Bosch and Rexroth hydraulic system.
driver’s cab
The advantages of the excavator cabin include improved safety and ease of operation. To operate the TVEKS EK-18 excavator became even easier, and all the attention of the driver is focused not on the controls, but on the work process.
The cabin was developed by a Russian production company. It has a large glazing area, excellent vibration isolation and standard heating. An optional air conditioner, a smaller adjustable steering wheel, an individually adjustable driver’s seat and joystick control system are available.
The position of the driver’s cab in relation to the chassis has changed slightly. Now the entire working area is in the field of view. This innovation allowed the EK-18 to become a competitor to foreign machines of the world brands. At the same time, the price to quality ratio of the domestic model is several times higher than that of the foreign optional equipment.
The dashboard includes controllers and controls, the location of which is carefully thought out. The cabin of the excavator TVEKS EK-18 has several compartments for the things – tools, first-aid kits, personal belongings, etc.
Appendix

Cost of new and used
Price of TVEKS EK-18 without mileage in standard configuration is 5.2 million rubles. The modifications are more expensive, the average price of EK-18-90 ranges from 5,5 mln. rub. to 5,7 mln. rub. To buy a used TVEKS EK-18 for at least 760 000 rub. The final price depends on the condition and production of the machine.
The lowest price for excavators made in 2009-2010 years, as they need major repairs or not all the parts of the equipment are installed. The model is versatile for construction work on large sites and the development of small areas. The advantage of the excavator is wheel configuration 4×4, but when it is necessary to work in conditions with weak soil or a large slope, it is not reasonable to use ЕK-18. Thanks to the low noise level and high-quality exhaust, the excavator can be used in urban areas and for work in agriculture, quarries and road construction.
equivalents
The TVEKS EK-18 excavator has several analogues, including EO-33211 and EO-4321.
