| New Bobcat M-Series excavator design  Bobcat once again brings innovation to compact equipment with the introduction of the new M-Series excavators. The new compact excavators are re-engineered to deliver increased performance in a lighter machine. Throughout each model are enhancements that save precious time and labor, make operators more comfortable and provide peace of mind. The new E32 and E35 M-Series excavators are in the popular 3-to-4-ton weight class. These two machines follow the introduction of the new M-Series E80, which is in the larger 6-to-8-ton weight class. With the M-Series introduction, Bobcat is instituting a new numbering system for excavators. The new machine numbers now correspond to the excavator's weight in metric tons. For example, the "32" in E32 is for 3.2 metric tons.Bobcat has completely re-engineered the design of M-Series excavators, reducing the weight to create a lighter machine. A new load-sensing piston pump and closed center-valve system deliver exceptional metering for smooth control of machine functions. With the new advanced hydraulic system, Bobcat was able to increase the arm breakout force by 10 percent over previous models. The E32 is a Conventional Tail Swing excavator, and the re-engineered house has reduced the overhang by 45 percent from previous excavators of comparable size. The E35 is a Zero Tail Swing excavator that excels at working on space-constrained jobsites, such as next to buildings or other obstacles. Bobcat designed the M-Series excavators to use X-frame undercarriages. This new undercarriage has increased ground clearance and enables better shedding of debris for easier cleanup when work is finished. Dirt and other debris easily pass through this undercarriage, making cleanup faster and leaving less debris on the trailers. The new Auto-Shift travel on the E32 and E35 boost the machines' productivity. Backfill work goes faster with an accurate, productive angle blade. The E32 and E35 also include an Auto-Idle feature. The Auto-Idle feature, which can be enabled at the operator's discretion, automatically causes the engine to return to idle if the excavator's functions are not used for a period of four seconds. The machine automatically returns to the preset throttle position after the operator starts working again. The new engine, air intake, cooling and exhaust systems, along with an entirely new pump and valve system lower sound levels, resulting in a more comfortable, quieter machine. The overall sound levels have been reduced by more than 50 percent. A significant contributor to excavator productivity is the comfort of the operator. Bobcat has designed the cab so the operator is comfortable in the machine, whether spending one hour or a whole day at the controls. New adjustable armrests allow the operator to move the rests to a more comfortable position. The new E32 and E35 excavators also feature an integrated slew brake. The brake eliminates the need to manually engage a slew brake when transporting the machine, and provides infinite brake positioning. write your comments about the article :: © 2009 Construction News :: home page |
