Crawler excavator EK 270 KRANEKS technical characteristics and description

In 2003, the domestic manufacturer of special equipment KRANEKS launched the serial production of advanced 05 series excavators. It is worth noting that the manufacturer planned to make this transition a long time ago, but due to the deep refinement and improvement of the 03 series, this process was delayed. New machines have excellent technical and operational characteristics, which allows the equipment to be used in almost all areas, including mining. This equipment is also famous for its versatility, which is explained by the presence of a large number of additional equipment, including clamshell buckets, hydraulic breakers, a variety of earth-moving buckets, and auger drilling units.

Description and features

KRANEKS was founded in the late 1990s by taking over a well-known state-owned enterprise. In a fairly short time, the company has become one of the leading companies in Russia. In addition to special equipment, KRANEKS also specializes in the production of various industrial and construction equipment. All products are of high quality and reliability, which is what allowed us to gain great popularity in the market.

One of the most popular excavators from this manufacturer is the EK 270, which has a tracked platform and a lot of modern technologies that can both increase productivity and simplify management.

This crawler excavator has the following advantages:

1. Huge service life of the entire structure.
2. Affordable cost of parts and wide distribution of spare parts.
3. Increased performance of the power plant and hydraulic system.
4. Simple and comfortable control.
5. Spacious cabin with all the necessary equipment for comfortable and long work.
6. Versatility.

The design of the EK 270 uses many different elements manufactured by foreign manufacturers, which significantly increased the reliability and reliability of the equipment. The entire control system here is used from Bosch. It is worth noting that most modern excavators are equipped with Bosch hydraulics, since this system functions properly even under the most severe operating conditions. In order to reduce the level of vibration vibrations in the operator's cabin, as well as on the excavator frame itself, special hydraulic supports manufactured by the manufacturer Simrit were used.

The excavator has a lot of positive reviews. The main qualities of this technology, which have created great demand, are high performance and strength of the entire structure. Moreover, with all this, the machine has a very affordable price, due to which the operation of the model is often observed in small companies.

High reliability and quality of all excavator elements was achieved through modern design methods, the use of modern equipment, the use of high-quality components, as well as through strict control throughout the entire production process. These elements themselves are made of low-alloy steel, which is characterized by increased durability and strength. The design also uses steel 10 HSND, but it is not used everywhere, but only in those elements that experience increased load. The basic digging bucket is made from Hardox steel.

Welding work is carried out using Kemppi semi-automatic welding machines. Esab materials are used, which are of high quality. All this, combined with modern technologies and advanced welding methods, has made it possible to significantly increase the strength of welds, which also affects the service life of the excavator.

The characteristic features of this model are high efficiency and increased reliability. Rotations of the entire superstructure are carried out using hydraulic pumps from the manufacturer Bosch and a planetary gearbox, which, by the way, for the EK 270 is manufactured by the Italian company Trasmital.

The undercarriage is traditionally an X-shaped frame to which the tracks are attached. A special feature of this frame design is its high resistance to torsion and bending, which provides increased stability when performing any work. The caterpillar beams have a gable surface, due to which soil practically does not clog in the platform elements. In addition, the track beams are also equipped with guide rails that prevent the tracks from accidentally jumping off the rollers. Speaking of rollers, support and tension rollers have a large margin of safety, thanks to which the equipment can operate under high loads for quite a long time.

The structures of the excavator handle and boom are also made by welding, but have a box-shaped section and special stiffeners that provide the working parts with high performance. It is worth noting that the stiffeners are located in places most subject to maximum loads. Thanks to all this, the equipment is capable of performing various operations in difficult operating conditions without failure and with maximum efficiency.

The hydraulic system of the EK 270 crawler excavator has been modernized, which made it possible to achieve high speed, smoothness, and precision movement of the working parts. Also, by improving the hydraulics, it was possible to significantly reduce fuel consumption. In addition to imported elements, domestic ones are also used in the hydraulic system, which reduces repair costs. Hydraulic cylinders are the basic elements of the entire system. It is worth noting that the manufacturer chose their location extremely well, which ensured a significantly increased service life of the hydraulic system. Hydraulic pumps have automatic recognizers that allow you to adjust hydraulic parameters in real time.

Separately, it is worth highlighting the cabin of this model, which is distinguished by its high strength and spacious workplace. Just like other elements of the machine, the cabin has a number of advantages:

1. Cabin doors and hatches have rubber seals that provide additional thermal insulation and noise absorption during operation.
2. All operating equipment control levers are located as ergonomically as possible and do not require much operator effort when performing any tasks.
3. The cab windows have large flat glass, which provides excellent visibility from the workplace.
4. Thanks to Simrit's hydraulic bearings, vibrations generated during the working process have been significantly reduced.
5. Inside there is a comfortable Grammer seat, which has a large range of adjustment and an ergonomic profile.
6. The Webasto preheater is equipped with its own timer.
7. The basic equipment includes a modern Eberspecher heating system, which provides an increased level of comfort when working at low ambient temperatures.

As additional equipment, the manufacturer offers the installation of air conditioning, a stereo radio and a fairly good sound system.

Even an inexperienced operator can handle this model, since the control system is as simple and convenient as possible. The controls are sensitive, allowing the operator to perform operations accurately and quickly.

The cabin is also equipped with a color multifunction monitor, which displays most of the most important parameters, namely fuel level, engine temperature, oil pressure, hydraulic pressure and much more. A special feature of this monitor is the ability to carry out pre-start diagnostics of all machine systems. All indicators and sensors were quite conveniently grouped, which has a positive effect on ease of operation.

The excavator is equipped with a domestically produced engine, namely a diesel power plant with the index YaMZ-236M2. The choice of this unit was made for a reason. Yaroslavl Motor Plant is one of the leading manufacturers in Russia, due to its high reliability and impeccable quality. Moreover, this motor is famous for its unpretentiousness, power and enormous service life, which is exactly what is necessary for any special equipment. An improved fuel combustion system was used here, which made it possible to achieve excellent power and economical performance.
