Optimized for ports, mines, steel mills, hard rock earthmoving applications
High Reliability
•Robust countershaft with oil passage outside design prolongs the life
•Caterpillar patented design aluminum cooling package guarantee 24 hours continuous operation.
•Main components designed and manufactured in house made at CQL, achieve best matching.
High Productivity
•The SEM PS bucket, utilizes a Caterpillar patented design, allowing 10% more material to be loaded into the bucket.
•Single pump hydraulic system, saving energy and improving efficiency.
•2700mm wheel base delivers bigger tipping loader and stability.
•Operating weight is 9900kg, more flexible.
• Engine conforms to National Stage II emission standards and torque converter is optimized, meanwhile it greatly improves traction force and reduces fuel consumption by 5%.
• With enlarged bucket, the productivity is improved by 12%.
• 18MPa hydraulic system pressure provides high efficiency and energy saving.
• Heavier counterweight provides larger load capacity.
• Rear-mounted fuel tank provides higher stability.
• Dump height is improved to 3.05m, which is the same as ZL50 loader.
• Brand new design of cooling system meets the requirements for -20℃ ~ +43℃ ambient conditions.
• Vibration absorption device is mounted with the engine, which further improves the seal performance and reduces vibration and noise.
• Working pump and SAE/DIN standard high pressure hoses are made at Caterpillar’s Wuxi plant, and the pipeline layout is optimized.
• Brand new electric system and circuit layout design and newly-added low pressure brake alarm improve the reliability and safety.
• The overall design meets the mandatory noise and safety standards in China.
