Crawler rope shovel 4100C AC

for mining

Overview
The 4100C electric rope shovel delivers reliable high-capacity loading for large-scale mining operations. With a nominal payload example of 81.6 mt (90 st) and a typical dipper capacity of 45.9 m3, the 4100C is an evolution of the proven 4100A platform.
