CAB

The EK 330 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.

ENGINE

The EK 240LC 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 250 hp (183 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.

The EK 330 excavator features an engine control mode selection system. In the Autogas mode engine speed is limited to a preset value irrespective of load for a maximum of 10 seconds. In the event of no-load or small load continuing for more than 10 seconds, the system automatically reduces engine speed to the original preset level, which permits maximum fuel economy. In the Autodiesel mode preset engine speed is constantly maintained irrespective of load, with no reduction during operation. This mode is used when the operator requires maximum engine power during the work period.

The multiple fuel cleaning system for removing dirt and water ensures long trouble-free operation of the high-pressure fuel pump and nozzles.

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 330 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.

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 330 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 330 excavator versatility and high output.
