Electric mining shovel
55 m³ | WK-55 Taiyuan Heavy Industry Co., Ltd.

Electric system adopts Rectifier/Regeneration to common DC Bus-bar and variable frequency speed adjustment. The electric control, taking PLC as the core, is a 3-stage system of up-position monitoring, field bus and frequency variable speed control. It is of futures of no disturbance to power grid allowing wider range of power voltage fluctuation and high power factor. The system is loaded with software to optimize the dig/cut curve and automatically optimization of hoist and dig power distribution. The system can realize self troubleshooting and running status display, electric power calculating and so on. This system has the advantages of state-of-art technology, reliable operation, high transmission efficiency and low power consumption.

WK-35 excavator is designed to match with mining trucks with capacity of 172MT to 326MT.

Technical characteristic:
Gear-rack crowding, powerful penetration, high efficiency;
Gear transmission uses gears of high hardness surface to have long life;
For swing and propel mechanism adopt planet reducer;
Propel adopts high hand drive to prolong life time;
Air release spring disk brakes are applied.
