| Increased comfort and performance in the new PC650LC-8  Depending on your point-of-view, the Komatsu PC650LC-8 hydraulic excavator is a large mid-size machine or a smallish large machine. Regardless of where it fits in your fleet, the approximately 143,000-lb., 429-hp unit is a productive, reliable piece of equipment that has improved upon the PC600LC-8. The most significant improvements of the PC650LC-8 center around 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 seven-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. Beyond these direct comfort and performance improvements, the PC650LC-8 has other features that owners and operators will appreciate. For example, the boom and arm have been strengthened; a fuel pre-filter with water separator is standard equipment; and the renowned Komatsu hydraulic system is protected with the most extensive filtration system available, including high-pressure in-line filters for each main pump. These features improve machine reliability and reduce the likelihood that the unit will break down on the job, resulting in costly downtime. The PC650LC-8 is also a class leader in terms of reducing fuel consumption and harmful emissions. It offers several operational modes that allow the operator to match engine output to the work at hand, thereby lowering fuel consumption. As with all Komatsu excavators, the PC650LC-8 comes with an industry-leading, low-noise, comfortable cab; easy access to maintenance and service functions; and the KOMTRAX machine monitoring and management system that allows your distributor to help you keep an eye on your machine to assure that it's running properly and to remind you about service intervals. write your comments about the article :: © 2011 Construction News :: home page |
