• Engine conforming to National Stage II emission standards, optimal power system, improved lifting capability, higher productivity and fuel efficiency.
• 19MPa hydraulic system pressure provides high efficiency and energy saving; single lever enables less efforts and convenient operation.
• Heavier counterweight, higher load capacity, and rear-mounted fuel tank, provides higher stability and the refueling is more convenient.
• Electronic controlled fixed axle type transmission produced with Caterpillar technology brings industry leading reliability and durability.
• Front and rear axle independently made by CQL features high brake efficiency, high reliability and durability.
• Brand new design of cooling system meets the requirements for -20℃ ~ +43℃ ambient conditions. Optional cooling system for 50℃ ambient conditions is also available.
• Increased steering pressure makes 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.
• Luxurious cab, seat, air conditioner and optimized operation control system.
