The Komatsu “-8” series excavators continue to uphold Komatsu's excellent performance while incorporating improvements and upgrades. They adopt a new high-pressure common rail electronically injected engine that enables more complete fuel combustion and achieves reduced fuel consumption while meeting Tier 3 emission standards; they feature a 7-inch large LCD monitor; the newly designed tubular-structure cab further enhances operator safety; and reinforced booms and reinforced arms are adopted for the Chinese market.

 

　　The high-pressure common rail electronically injected engine of the Komatsu PC200-8 hydraulic excavator achieves low consumption and high efficiency; high durability ensures long-term stable operation of the machine; it provides a comfortable operating environment that makes long hours of operation less tiring; the high-rigidity cab fully protects operator safety; and it is equipped with an environmentally friendly engine that complies with EPA Tier 3 and EU Stage 3A emission standards. The machine's operating weight is 19,900–21,990 kg, with a standard bucket capacity of 0.8 m3.

 

　　Consistently high-standard Komatsu quality

 

　　Komatsu has long been renowned in the industry for its extremely high equipment quality. The PC200-8 model embodies Komatsu's consistent high quality to the fullest extent. Equipped with the latest technology and giving full attention to equipment safety, high efficiency and high productivity—this is the Komatsu quality embodied by the PC200-8 model.

 

　　The high-pressure common rail electronically injected engine achieves low consumption and high efficiency, and the outstanding pressure-compensating CLSS hydraulic system minimizes the power loss of the new SAA6D107E-1 engine. The perfect combination of the two, together with the work-priority fast mode that enables large workloads and the economy mode that automatically lowers engine speed and prioritizes fuel savings, achieves high work efficiency while reducing fuel consumption. At the same time, the newly developed Komatsu SAAD107E-1 [ecot3] engine significantly reduces nitrogen oxide emissions and complies with EPA Tier 3 and EU Stage 3A emission standards.

 

　　Precise multi-stage fuel injection is controlled by the engine so that fuel is fully burned. The high-pressure fuel injection system developed specifically for construction machinery provides overall engine durability. Efficient matching technology between the engine and hydraulic devices is adopted. Through the above technologies, the excavator's fuel consumption per unit time is significantly reduced, and it also features functions that promote energy-saving operation, such as E mode and an economy operation indicator light. To prevent unnecessary fuel consumption, if the engine idles for more than 5 minutes, an idle warning is displayed on the monitor to remind the operator to save fuel.

 

　　Advanced total machine control

 

　　The engine, hydraulic devices, the electrical system that highly controls the engine and hydraulic devices, and major components are all researched, developed and produced by Komatsu itself. With this “essence of Komatsu technology,” and through “face-to-face” communication with users, “Komatsu technology” continues to advance and accumulate, thereby reaching extraordinary heights.

 

　　Total machine control is achieved through the engine controller, enabling high fuel pressure and high-precision multi-stage injection, and combining the machine's major components with operating conditions to perform control of control valves, main pump oil pressure and flow, etc. While maximizing the machine's potential, it also greatly reduces fuel consumption. Through total control, the machine reduces hydraulic losses and lowers fuel consumption per unit time, fully demonstrating its energy-saving operation functions, thus giving birth to an environmentally friendly new generation of equipment with outstanding performance.
