The Electric Shovel’s electric system features rectifier/regeneration to communal 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. They cause no disturbance to the power grid allowing a wider range of power voltage fluctuation and high power factor. Their systems are loaded with software which optimizes dig/cut curves and automatically optimizes hoist and dig power distribution. This system automatically troubleshoots, displays running status, and calculates electric power. Using state-of-the-art technology, this system is highly reliable, highly effective, and energy efficient.
