RTM652B
Series: C Series Wheel Loader
Work Conditions: Heavy Work Conditions
Capacity: 5t

Features
• Engine conforming to National Stage II emission standards, optimal power system, improved lifting capability, higher productivity and fuel efficiency.
• Front and rear axle of unique design and SI axle Caterpillar technology, and wet brake system, featuring high reliability and durability.
• 19MPa hydraulic system pressure provides high efficiency and energy saving; single lever enables less efforts and convenient operation.
• Caterpillar PS bucket has small resistance and high load factor, which improves the production efficiency by 12%.
• Lengthened wheelbase, heavier counterweight, higher load capacity, and rear-mounted fuel tank, provides higher stability and the refueling is more convenient.
• Working pump and steering pump made by Caterpillar’s Wuxi plant, SAE/DIN standard high pressure hoses and optimized pipelines.
• 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.
• The electric system is upgraded and adopts high grade waterproof and dustproof plugin guarantee system, which is more safe and reliable. The overall design meets the mandatory noise and safety standards in China.
