WK-12 Forward Excavator

Product Detailed

WK-12 Forward Excavator: Gear-rack crowding, powerful penetration, high efficiency. Air release spring disk brakes are applied

WK-12C excavator is suitable for 10 million MT mining use, to match with 80-154MT dumper or 100MT dumping train.

Technical characteristic:

·Gear-rack crowding, powerful penetration, high efficiency

·The propel mechanism adopts independent drive of planetary reducer;

·Gear transmission uses gears of high hardness surface to have long life;

·Propel adopts high hand drive to prolong life time;

·Air release spring disk brakes are applied(exclude hoist brake);

·AC IGBT drive.
