The machine is able to operate efficiently in temperature modes from -40 ° C to + 40 ° C, which allows its use in virtually all regions of the country. Having dimensions 8200x2500x3140 mm (length-width-height), weight of 13400 kg, can develop speed up to 25 km / hour.
  Considering the excavator EK 14 specifications  it is more convenient to provide in the form of a table:

The capacity of the fuel tank is 255 liters. Fuel supply is regulated by means of a lever in the cabin. The noise level is reduced by the sound attenuator on the exhaust manifold of the power plant.

Controls located in the cockpit

The work of the excavator systems and mechanisms is displayed on the electronic panel, which includes:
  1. Display - shows the numerical parameters of the operating parameters
  2. Indicators - indicate the operational processes carried out by the machinery
  3. Lamps of control - notify about the functioning of various devices or a violation in their work.
  In the cockpit there are also pedals and control levers, switches, switches of various systems and units, handles for fixing.
  The direction of movement of the entire machine is changed by means of the steering wheel. The general structure and equipment of the cabin is very convenient. Additional comfort gives good visibility, created due to large glass front and sides.

  Fuel consumption

Such an indicator as fuel consumption can not be unambiguous and depends on some parameters: engine type, EC modification 14 (20, 30, 60), soil category.
  So, with the engine D243, the fuel consumption is 6.9 l / h, with the engine D245 and the hardness of the soil of 1-2 categories - 8.4 l / h, and the modification of the excavator EK 14 20, for which D245C is installed, the flow rate increases to 9, 5 l / hour.
  There are other modifications: EC 14 30, EC 14 60, EC 14 90, on which the foreign hydraulic systems Bosch-Rexroth

Earth-moving equipment

The length of changeable handles has 4 indicators. Accordingly, some characteristics change, for example, bucket volume, range and depth of digging, height (ceiling) of loading.
  The engine is mounted using rubber shock absorbers, which reduces the impact of vibration. Chassis frame and working tool, have reinforced construction. The equipment has good maneuverability and can be used in hard-to-reach areas due to the small turning radius of the platform.

Advantages and disadvantages

This technique has a lot of indisputable advantages, among which it should be noted:

• the possibility of multi-purpose use (due to the completion of additional removable equipment);
• increased working life, due to the strengthened running frame, increased power reserve of metal structures;
• high performance, easy management, availability of maintenance;
• convenient working place, comfortable arrangement of devices in the cabin.

TO shortcomings  The design can include the mains voltage, which is 12 volts. When working in the conditions of frost, this voltage is not always enough to start the equipment and often have to resort to the services of other vehicles ("light up"), or have a spare battery.

  Completion of the excavator with additional equipment

In addition to the handles of different lengths, the EK 14 is equipped with replaceable units:

• canine-ripper, with which you can tear down frozen layers or asphalt concrete;
• greyfer (sometimes with a hydro rotator);
• hydraulic hammer, intended for the destruction of solid bases, as well as for ramming or crushing.

Thus, the functionality of the excavator is expanded with new available operations.
