EKG12

Crawler-mounted shovel EKG-12 is a new model designed for mining and loading overburden rock and resources into transport facilities or into the mined-out space. Main engineering features of excavator are double-leg dipper handle, rack crowd, double crawler with individual drive for each crawler. It provides mobile activity of a shovel in the most high-gravity pit-faces and climatic conditions. aclinal bracket, provide easiness of erection, centering adjustment and execution of repair works. The forced air-cooling of the propel motors provides unlimited practically drive operating regime at travel along prepared route at the velocity up to 1.1 km/h. Two-axis hand-worked command-apparatuses, the devices for vibration insulation of operator seat and air-conditioning system create the comfortable conditions for excavator driving. Electric drive of the shovel main mechanisms is made as the motor-generator system, controlled by thyristor energizers. Electric driver control system provides optimal mechanical characteristics of drive at high efficiency. Electric drive system is easy to maintain, reliable and provides low operation expenses. omz mining equipment and engineering

constructional peculiarities

excavators

The front-end equipment is manufactured of high-strength steels, ensuring trouble-free operation under high dynamic loads. A specific geometry of dipper allows to load rocks into the trucks with 75 -120 t capacity, and also into the railway dumpcars.

Rotation gears are planetary. They are more compact and reliable in comparison with cylindric ones. The equally-spaced location of gears excludes a radial loading on bearing of king journal.

The boom is hold in the operative position with four guys, ensuring reliability in operation.

The crawler is with open large rollers, with arranged above the ground tumbler sprockets, equipped with replaceable driven teeth. Driven electric motors, located on
