Excavator Drum Cutter Description
The Excavator drum cutter is composed of a hydraulic motor, out body, and one or two drums equipped with some number picks on it. One drum is a vertical hydraulic drum cutter, two drums are horizontal. When the excavator hydraulic system offers hydraulic power to the drum cutter motor, it would drive the drums to rotate. Then those picks start to rotate at a high frequency to deal with demolition work (rock, concrete), milling, tunneling, softening the frozen ground and etc.
