| New 1.5-ton Bobcat compact excavator  A redesigned work group allows the new Bobcat 324 compact excavator to reach farther, dig deeper and dump higher. The 324 excavator is a Conventional Tail Swing unit in the 1.5-ton operating class. Its boom cylinder is attached to the top of the boom instead of the bottom, giving it more protection from damage while digging. It also features a lighter-weight yet durable boom fabrication with cast pivot joints. As a result, the 324 offers a maximum dig depth of 8 feet 6 inches, reach at ground level of 14 feet, and dump height clearance of 8 feet 8 inches - all of which are best in class.The undercarriage on the 324 excavator hydraulically retracts to a width of just 38.6 inches for travel through gates and doorways, or alongside homes. It can then expand to 53.7 inches for greater performance. Overall height is just 85.5 inches. A 13.9-horsepower, Tier 4 water-cooled diesel engine powers the 324, and two travel speed ranges are standard. Equipped with a hydraulic system similar to the larger Bobcat excavators, the 324 has impressive cycle times and breakout forces to complete jobs faster. The system's torque-limiting piston pump is able to sense and react to hydraulic loads, for better utilization of the engine's torque curve. The standard dozer blade features two self-storing extensions that provide a working width of 54 inches. Auxiliary hydraulics with boom-mounted, flush-face quick couplers make changing attachments easy. Boom swing on the 324 excavator is 80 degrees to the left and 60 degrees to the right. Bobcat's exclusive in-track swing frame keeps the swing castings and cylinders within the width of the tracks when digging in an offset position, helping the operator dig flush against an obstacle. A TOPS/ROPS canopy with comfort seat, retractable seat belt, cup holder and armrests is standard. An enclosed cab with heat is optional. Available attachments include grading and trenching buckets, an augur, a hydraulic breaker and a hydraulic clamp. write your comments about the article :: © 2010 Construction News :: home page |
