Quarry shovel EKG-10



The excavator is designed to excavate and load mineral products and overburden rock to transport facilities at open mine workings, for stacking and also for loading works at storage area.
Models EKG-5U and EKG-8Us were produced on the basis of excavator model EKG-10. Excavators with elongated working equipment may be used for digging basic trenches, and also for loading on transport facilities, located in overlying lifts.
EKG-10 and its modifications provide high productivity, good mobility, easy control and maintenance. Up-to-date design and high-strength materials applied in these excavators provide its reliable operation in any climatic conditions.

constructional peculiarities


The shovel is equipped with up-to-date electronic system on the basis of thruster converters providing independent stepless control of the main drives and formation of optimal static and dynamic characteristics according to “generator-motor” scheme. The system is provided with necessary blockings to ensure reliable and safety excavator operation. Block design of converters provides easy troubleshooting and repair.

A saddle bearing with adjustable side and upper rollers for directing of stick motion at crowdreturn is applied in the excavator. This enables to compensate wear and to reduce dynamic loads on the excavator working equipment.

Planetary gearboxes of the hoist and swing mechanisms in comparison with early used gearboxes are more compact, have larger load-carrying capacity, and are reliable and durable in work. Gear drives are made of high-alloyed steels with surface thermal hardening.

Single-beam stick is made of high-test punched tube. The dipper is flanged to the stick stationary with high-strength bolts providing easy replacement and high reliability (no gaps and mobility in connections).

The stick is unloaded from torsion, and is fitted with damping mechanism of duplex action, installed in the rear stick part. A removable recurring half block with high surface hardness is installed in the front part of the stick.

The shovel is fitted with electrically driven cable reel for reeling and unreeling of the cable when the excavator is moving and during its operation in the face. Cable reel capacity is 630 m.

The cabin elevated over machinery house provides good field of view during operation. The cabin is spacious, sealed, provided with heating, conditioning, ventilation, glass heating and also with vibroinsulated seat.
