BUCKET WHEEL EXCAVATOR KWK-910 - SKW

SPECIFIC FEATURES OF THE MACHINE
A crawler drive mechanism is equipped with the wellproven
fixture of the movement wheels of long life type,
facilitating the lubricating system. The control with an
inverter ensures a smooth regulation of the drive speed and
enables driving at various speeds of particular crawlers,
which facilitates turning.
Three-point support for the carriage is based on ball-andsocket
joints with modern bronze lining of high durability.
The steering with a hydraulic cylinder provides a turning
radius R= 25 m, unique for 6-crawler machines, and secures
the support system and undercarriage structure against the
loads resulting from the interaction of passive forces from
the foundation.
The slewing mechanism consists of four drive systems with
hydraulic drives cooperating with a toothed ring of the
module m=27. Flexible support for the moment levers and
securing devices in the hydraulic system buffer the effects of
side impact loads from the digging organ.
The system of the bucket wheel boom lowering is equipped
with a modern hoisting winch with a double drive
controlled with an inverter. Such a solution ensures a fluent
speed and boom lowering regulation with an option of
changing the direction of lowering without pawling of the
hoisting winch brakes.
