Komatsu Excavators PC2000-8

PC2000-8 Hydraulic Excavator

Komatsu’s “Operator First” design concept is exemplified in the PC2000-8 Hydraulic Excavator. The cab is designed for mining with 30% more cab volume, a full front window with two wipers, OPG level 2 top cab guard, extensive exterior lighting, a 7" LCD color monitor with Eco-gauge and an air suspension seat. The operator can tailor his machine performance using the Economy, Power or Heavy Lift modes for maximizing efficiency.
