• Engine conforming to National Stage II emission standards, optimal power system, improved lifting capability, higher productivity and fuel efficiency.
• With enlarged bucket, the productivity is improved by 12%.
• 18MPa hydraulic system pressure provides high efficiency and energy saving; single lever enables less efforts and convenient operation.
• Enlarged wheelbase, heavier counterweight, higher load capacity, and rear-mounted fuel tank, provides higher stability and the refueling is more convenient.
• Reliability of transmission and front and rear axle is improved; the service and maintenance is convenient.
• Brand new design of cooling system meets the requirements for -20℃ ~ +43℃ ambient conditions. Optional cooling system for 50℃ ambient conditions is also available.
• Full hydraulic coaxial flow amplification steering system improves steering pressure and enables more quick and easy steering.
• Vibration absorption device is mounted with the engine, which further improves the seal performance and reduces vibration and noise.
• Working pump steering pump, and SAE/DIN standard high pressure hoses are made at Caterpillar’s Wuxi plant, and the pipeline layout is optimized.
• Brake booster and brake chamber are moved to the central left service section of the machine, which is more convenient for service and maintenance.
