  • Engine RPM control system with auto deceleration
  • New variable transmission cut-off system
  • New dual-mode active working hydraulic system
  • Additional torque converter cooler
  • Increased hydraulic cooling capacity
  • Extended service intervals

Rolling Meadows, IL, September 8, 2010 - Komatsu America Corp. (KAC) today introduced its new WA1200-6 Wheel Loader for use in mining applications. Based on extensive customer input and feedback, the new loader includes environmental, technological and ergonomic enhancements for even greater productivity, while lowering operating costs.

The new WA1200-6 is powered by a highly-efficient Komatsu SAADA16V160E-2 engine that delivers 1892 Gross HP at 1800 RPM. With an operating weight of 477,100 lbs., the new loader offers increased fuel efficiency, while meeting all EPA Tier 2 emissions requirements.

Special features of the WA1200-6 include:

·         Productivity Performance

The engine net output of the WA1200-6 has been increased by 132 HP to 1765 HP at 1800 RPM.  The use of an electronic governor results in low fuel consumption, with quick throttle response to match the machine’s powerful tractive effort and fast hydraulic response.    

The new dual-mode active working hydraulic system allows the operator to select between normal and powerful loading, while the optimum oil flow in the working system increases efficiency and reduces cycle times. Increased engine output and the optimized hydraulic system provide outstanding production and performance.

·         Operator Enhancements

The engine RPM control system with auto deceleration allows the operator to set the engine RPM at the optimum work performance level and control speed smoothly with the accelerator. The variable transmission cut-off system for the left brake pedal is adjustable by a switch at the operator’s seat.  When loading, the low setting reduces brake impact to prevent spillage, while the high setting can be used for traveling.

·         Improved Reliability and Durability  

An additional torque converter cooler was added as standard equipment to reduce oil temperature and increase cooling capacity.  For hydraulic cooling, a new pump with increased oil capacity was added and the circulation was revised to lower oil temperature. Two additional air cleaners were added and the size of the elements increased to 15 inches for more capacity.
