• 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.
