Komatsu Excavators PC800LC-8

PC800LC-8 Hydraulic Excavator

Got mass quantities of material to move or tough conglomerate to dig through? The PC800LC-8 Hydraulic Excavator could be the answer you're looking for. Economy or power working modes, smooth or power boom modes and a shockless boom mode give the operator the tools he needs to optimize the production of his machine. In a Super Digger configuration, with two arm cylinders, digging force is increased by 19%.
