CAB

The EK 240 excavator’s robust and reliable cab has everything needed to ensure maximum operator output and comfort.

  • Simrit, hydraulic mounts reduce vibration;
  • Rubber seals on doors and hatches ensure sound and heat insulation;
  • Ergonomically designed Grammer seat adjustable for a wide range of positions;
  • Conveniently located controls from Bosch Rexroth requiring minimal effort with levers and pedals;
  • Additional comfort provided by Eberspacher heater;
  • Good visibility provided by large cab windows with flat glass for quick replacement in case of damage;
  • At customer’s request, an acoustic stereo recorder may be provided as an agreeable further option, also an air conditioner for comfortable operation in hot climates.

CONTROLS

The EK-24- excavator’s new state-of-the art ergonomic design and multifunctional control panel performs prestart and current diagnostics of excavator systems, warns the operator of any malfunction or operation exceeding critical parameters, with flexible choice of excavator operating modes and hydraulic system and engine control.

The control panel’s LCD, featuring four indicators and four annunciators permits total control of engine temperature and pressure, hydraulic fluid and coolant temperature, fuel level, and their critical parameters.

The multifunctional STOP indicator warns the operator of emergencies, giving coded information on excavator unit malfunctioning during prestart diagnostics. Многофункциональный индикатор «STOP» информирует оператора о возникновении аварийных ситуаций, высвечивает информацию в виде кода о неисправности узлов экскаватора в период предпусковой диагностики.

A system for automatically changing indicator illumination intensity and highlighting depending on outdoor lighting, together with non-reflective front panel surface ensure maximum operator comfort at all times of the day.

Active protection against operation in excess of critical parameters, STOP indicator and buzzer significantly simplify excavator system control and enable the operator to fully concentrate his attention on his job, resulting in higher labour efficiency.

ENGINE

The EK-240 features a Deutz 6-cylinder turbocharged diesel engine with charged air cooling, characterised by high reliability, economy and low maintenance requirements. The Deutz diesel engine develops 172 hp (127 kW), complies with EURO 3 emission standard requirements and ensures high excavator power, output and long service life in all operating conditions.

An optional Webasto prestart heater may be installed for efficient engine starting at low ambient temperatures.

HYDRAULIC SYSTEM

The EK-240 excavator’s hydraulic system ensures rational power consumption, smooth, precise and rapid performance depending on operating conditions and the nature of the work performed.

The hydraulic system is easy to operate and versatile (suitable for all attachments), and develops operating pressure of 37.5 MPa permitting maximum output with reduced downtime.

All excavators are equipped with a complete set of imported hydraulic equipment from Bosch Rexroth, cushioned hydraulic cylinders from Hydrauto and rotary distributors from Haldex.

The EK 240 features a system permitting selection of operating modes (six modes in all) to adjust engine and pump speed and hydraulic system pressure to the nature of the job. This system enables equipment characteristics to be adapted to specific job requirements and, resulting in flexible machine operation. The Power Boost hydraulic system mode permits a 10% increase in maximum attachments power for about 8 seconds, if required by the current task.

METAL STRUCTURES

Modern CAD technologies, high-quality materials, equipment from the world’s leading manufacturers, stringent quality control at all production process stages guarantee consistent quality, high precision and reliability of EK 240 excavator metal structures.

All metal structure parts are made from low-alloy steel, ensuring enhanced robustness and reliability. Parts subjected to particularly heavy loads during operation are made from high-tensile grade 10CrSiNiCu steel. Buckets are made from high strength and wear resistant Hardox steel.

Welding is performed using Esab materials and semiautomatic welding machines from Kempi with carbon dioxide-argon mixtures. Innovative welding techniques and modern equipment ensure high weld durability, and thus consistently high metal structure quality.

Butt welding of pipes is performed using computerised Esab equipment, which ensures enhanced reliability and durability. Ultrasonic weld inspection precludes internal defects.

CRAWLER UNIT

KRANEKS crawler units are characterised by high reliability and durability, ensuring efficient operation in all soils.

Track assemblies, rollers and tensioners from Valuepart, track drive gearboxes from Bonfiglioli ensure enhanced excavator reliability during travel, and also the required traction along inclines and during excavator turning.

The X-shaped crawler frame ensures high resistance to bending and torsion forces. The crawlers beams’ convex surface reinforces structural strength and prevents soil build-up.

Guide rails along the crawler beams prevent slipping of lower rollers from track belts.

ATTACHMENTS

Booms and arms are welded box section structures provided with special stiffening ribs (webs) in areas subjected to maximum stress. They are designed for efficient, trouble-free operation of EK 240 excavators even in the toughest conditions. Buckets reinforced with Hardox steel are provided as standard equipment.

A wide range of optional attachments (buckets of various shapes and capacities, hydraulic breakers, rippers, twisted augers, clamshells) facilitate EK 240 excavator versatility and high output.

 

The policy of the MG KRANEKS is aimed at constant improvement of the products, so MG KRANEKS reserves the right to modify the specifications of its machines without prior notice and without incurring obligations relating to such changes.
