  • CAT 314D LCR Track Excavator

    If your work space is restricted, the 314E CR makes an ideal choice because it can get up close to new residential construction, buildings, fences, hillsides, or any other “crowded” environment with ease. When rotated 90 degrees and working over the side, the 314E CR’s counterweight extends only a bit beyond the track width and doesn’t exceed the length of the track at all. This significantly reduces the risk of your operator damaging the machine and surrounding structures in full swing, which makes for a safer work environment and lower owning and operating costs for your business.
