| New excavator from Liebherr  Liebherr introduced a new 250-tonne class excavator. The R 9250 Litronic is the successor to the R 994 Litronic. The R 9250 is powered by a 12-cylinder Cummins turbo-charged diesel engine rated at 960 kW. The standard version of this new large excavator is equipped with a 9m gooseneck boom, a 4m stick and a 15m³ backhoe bucket. With a 15% larger bucket capacity than the R 994 which it supersedes, 42% higher swing torque and high digging capabilities, the 250 tonnes R 9250 Litronic is set to deliver even greater productivity. Only three bucket loads are required to load an 80 tonnes dump truck, or four to five bucket loads for a 120 tonnes dump truck.The driver's cab on the R 9250 Litronic is identical to the R 996 Litronic as far as size, specification and ergonomic design are concerned. It is fully air-conditioned and the driver is protected against sunlight and noise by blinds, tinted windows and high quality sound insulation. The driver's seat can be adjusted to cater for the individual size and weight of the driver. The generously dimensioned glazing provides an excellent view of the work area and, because of its comfort and ergonomic layout, the cab provides ideal conditions for maintaining maximum operator efficiency throughout the day. The electro-hydraulic control system in the R 9250 Litronic ensures optimum response and precision and makes the machine easy and safe to operate. The driver can obtain up-to-the-minute operational data via the ergonomically designed monitoring display. Improved serviceability was another important goal in the development of the new R 9250 Litronic. The engine and pump compartment is spacious, allowing service personnel access in a standing position and offering easy access to the drive components for maintenance. The passageway between the engine compartment and the counterweight also cuts down service time. All service points on the R 9250 Litronic are arranged for easy access and - where possible - are assembled at a central point. write your comments about the article :: © 2006 Construction News :: home page |
