Komatsu PC650LC-8 hydraulic excavator boasts improvements over the PC600LC-8. The approximately 143,000-pound, 429-horsepower unit includs an improved operator environment that provides better operator comfort and control. The new, highly rigid cab includes a heated, high-back, air-suspension seat; a 7-inch LCD color monitor panel; and a standard rearview camera that gives the operator the visibility and control to maximize productivity. Additionally, an Arm Quick Return Circuit on the PC650LC-8 returns a portion of oil flow to the hydraulic tank at arm dumping to reduce hydraulic pressure loss. Combined with a new Arm Regeneration Valve, the work equipment speed has increased, enabling faster truck loading.
