Video about the EK-18 excavator
The EK-18 excavator is a wheeled vehicle manufactured by the Tver plant (known as TVEKS). This excavator is often used in various construction works, both large-scale objects and roads. Unlike its tracked counterparts, the EK-18 has a fairly high travel speed, at least for an excavator. And also it does not damage the area on which it works, thanks to which this excavator can be used on asphalt areas and other similar surfaces. It is worth noting that of the entire line of machines of this manufacturer, the EK-18 excavator is the most popular, since it differs from the others in its increased carrying capacity, reliability and durability. Equipped with base model diesel engine D-245, developed at the Minsk Motor Plant, which is often found in MTZ tractors. This engine is capable of delivering maximum power at certain rpm. crankshaft, 77.2 kilowatts or 105 horsepower. But on some modifications, a power unit from the manufacturer Perkins is installed, this engine is slightly more powerful than the previous one and is capable of delivering a maximum power of 90 kilowatts or 123 horsepower. An excavation bucket with a volume of one cubic meter is installed from the factory, but if necessary, it can be replaced with a larger one and vice versa.

Appointment
The main area of this excavator is construction. The EK-18 has proven itself quite well due to its versatility, since almost all construction and dismantling works can be performed using this machine. First of all, it is intended for carrying out earth-moving processes, namely, this is the digging of trenches and pits, as well as their filling (due to the presence of a hydraulic frontal blade). The standard cubic meter bucket can also be used for loading and unloading bulk cargo.
In order for it to be used in the process of dismantling work, special equipment is installed to it, with the help of which it performs such work as the destruction of brick and concrete structures, cutting scrap metal and much more.
Attachments
As we can see, the EK-18 excavator has a fairly wide purpose. This is due to the presence of additional equipment necessary to perform a certain job. This machine uses the following attachments:
As standard, the excavator is equipped with a front hydraulic blade, which is used to level the working area and fill various holes (including trenches). It also has an excavating bucket, the volume of which is one cubic meter, but if necessary, this bucket can be replaced with a larger one or vice versa, depending on the type of work.
When doing earthmoving, almost every technique needs high stability in order to avoid tipping the machine. For this, special hydraulic supports are installed as standard, usually located at the rear of the excavator, on the sides. Also, the EK-18 has these supports from the factory.
In addition to the basic equipment, this excavator also uses additional attachments, with which it mainly performs dismantling types of work. This set consists of the following hydraulic attachments:
- Hydraulic hammer model MG-300. It is the main unit used for the destruction of various road surfaces, both concrete and reinforced concrete. It can also be used for construction purposes, namely for loosening frozen soil, and for tamping soil with a loose structure. Installed on an excavator boom instead of a bucket.
- Hydraulic shears or concrete breaking equipment. There are only two models of these units, namely IG-811 and IG-821. It is also used for dismantling purposes, namely the destruction of brick structures and biting of scrap metal. It can also be used for the complete dismantling of railways, where an excavator with this equipment cuts the rails and moves them for further loading. The scissors have a rotator that allows you to turn not any required angle. They are installed in the same way on the excavator boom instead of the excavation bucket.
- Loosening equipment. It is used not only for dismantling purposes, but also in construction, where it loosens frozen soil for further operations. For any excavator, including the EK-18, there is only one-shank hydraulic ripper. The installation is exactly the same as with the previous units - on the boom instead of the bucket.
In forestry, the EK-18 excavator uses a hydraulic log gripper, which, like the shears, has a full-turn rotator. It is mainly used for loading and unloading operations, but also, using this equipment, the excavator is capable of stacking logs. It is installed on the boom instead of an excavating bucket without the use of a special adapter (however, other units do not need it either).
Modifications
The EK-18 excavator, like all other special equipment, has modified versions designed for a certain type of work. In total, six modified versions have been developed, such as:
- Modification EK-18-20. From the factory, this version of the excavator is equipped with an excavating bucket with a volume of one cubic meter. In contrast to the basic machine, this modification has increased productivity, and is also adapted for doing work with a fairly high load. This is due to the additional structural reinforcement of all excavator equipment. And also can be aggregated with all available additional attachments, which made it possible to expand the range of tasks performed by this model. Among all modifications, the EK-18-20 is a multifunctional and most powerful technique.
- Modification EK-18-30. In fact, this is a revision of the previous version of the excavator, in which an imported hydraulic system is installed, including its mechanisms. According to technical characteristics and appearance, the excavator of this model is completely identical to the previous one.
- Modification EK-18-40. It is a hydraulic pneumatic wheeled excavator, which has a special grab gripper from the factory. This model has found its application in all areas where loading of various materials is required, but mainly timber and scrap metal. Also, of the main differences of this version from the previous ones, it should be noted that a hydraulic lifting cabin and scrap equipment are installed on the EK-18-40. In technical terms, there are no changes.
- Modification EK-18-44. It is a special pneumatic modified version, which is equipped with a five-jaw grapple gripper model GP-554. This equipment has a volume of 650 cubic centimeters. The cab of this model is hydraulically lifted. There is a special full-revolving rotator for mounted hydraulic units. Scrap equipment is also installed, as in the previous modification,
- Modification EK-18-60. It differs from the previous ones in another power unit, namely this four-cylinder diesel from the manufacturer Perkins. There is a Bosch-Rexroth travel motor and a dedicated hydraulic pump. There are no more changes.
- Modification of the EK-18-90M. It is a deep revision of the EK-18-60 modification, in which the design of the working units of the excavator was changed and an improved engine was installed, which differs from other units with increased productivity (the manufacturer is the same - Perkins).
Specifications
The operating weight of the EK-18 excavator (basic model, as well as modified versions) is 18,000 kilograms. In length, this machine, taking into account the boom, has a value of 9400 millimeters. The width is 2500 millimeters. The height of the excavator is 3300 millimeters.
With a 2200 mm stick installed, the digging parameters have the following values:
The digging radius is 9100 millimeters when the radius at the parking level is 8850 millimeters. Digging depth (kinematic) has a value of 5770 millimeters. The height of unloading of various cargoes is 6240 mm, which is quite enough for a full-fledged earthmoving work. The angle of rotation of the digging bucket is 177 degrees. The maximum capacity of a standard excavating bucket (calculated in SAE) is exactly one cubic meter.
With a 2800mm stick installed, the digging parameters are as follows:
The digging radius has a value of 9650 millimeters. The digging radius at the parking level is 9420 millimeters. The kinematic digging depth is 6370 millimeters. The maximum unloading height has a value of 6500 millimeters. The angle of rotation of the excavating bucket is also 177 degrees. The bucket used with this stick has a volume of 770 cc.
With the largest, 3400mm stick installed, the digging values are as follows:
The maximum digging radius is 10,200 millimeters, at the parking level it is exactly 10,000 millimeters. The kinematic digging depth, it is also the maximum achievable, has a value of 6970 millimeters. The maximum unloading height is 6750 millimeters. The maximum bucket swing angle is 177 degrees. In this case, the standard bucket has a volume of 650 millimeters.
The base model and some modifications (EK-18-20, EK-18-30) are equipped with a four-cylinder diesel unit developed by the Minsk Motor Plant. This engine is named as D-245. It is capable of delivering rated power at a certain crankshaft speed, 77.2 kilowatts or 105 horsepower. Modifications such as EK-18-60 and EK-18-90M are equipped with a 1104C-44TA power plant developed by the manufacturer Perkins. This engine is capable of developing a rated power (also at certain crankshaft speeds) of 90 kilowatts or 123 horsepower. This machine can develop maximum speed at 20 kilometers per hour.
The base excavator is equipped with a hydraulic system of the PSM model. On the modifications (EK-18-60 and EK-18-90M), a German-made hydraulic system, the Bosch-Rexroth model, is installed. The maximum achievable pressure in the hydraulic system of the excavator is 28 megapascals.
Peculiarities
As described earlier, this excavator can be used on various surfaces (paved areas and similar areas), since it does not cause severe damage to the road surface, as, for example, tracked vehicles. Eco is explained by the wheeled chassis. The scope of the EK-18 is quite large, not only due to its high technical characteristics, but also the ability to use in the working process a large number of various additional attachments, with which the excavator is able to perform all necessary work, both for construction purposes and for dismantling. It should be noted that the EK-18 excavator was originally intended only for construction work, but later, with the advent of a log gripper (with a carrying capacity of 3000 kilograms), forestry also turned their attention to this machine.
The excavator is designed for tough work, as the auxiliary reinforcement will make the machine withstand the high loads that are common in the construction industry. It also has high reliability and durability of all units and mechanisms, which is an important parameter in any heavy equipment. But in case of detection of problems associated with the operation of any mechanisms, they can be eliminated in a short time without much effort, since the parts are arranged in a convenient order for the mechanic. Also, it is worth noting that on some modifications a special cabin is installed, which, if necessary, can be raised during work, while providing an even greater view. The cabin rises due to special hydraulics.
