SEM630B Wheel Loader
Optimized for renting, construction sites and sand factories and other loose material applications.
–Transmission box, hydraulic parts and frame are made at CQL. Structures were validated by using Caterpillar FEA finite element analysis and extensive field follow to realize the best fit.
–The transmission design utilizes a robust countershaft design. The oil tube was put outside which is facilitate for maintenance, so the using life is extended.
–All-aluminum cooling system, which can make sure 24 hours continuously work.
–High efficiency double pump independent circuits, joint operation quick response, which is much more flexible than the single pump circuits.
–The SEM PS bucket, utilizes a Caterpillar Patented design, the bucket collecting angle is increased to 50 degree, allows 10% more material to be loaded into the bucket, with less possibility of material scattering.
–2630mm short wheel base , with small turning radius, suitable for narrow space work.
–Machine operation weight is 9.7 tons, with more flexible operation and better fuel efficiency.
• Turbocharged 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%.
• DIN standard high pressure hoses are made at Caterpillar’s Wuxi plant, and the pipeline layout is optimized.
• With enlarged bucket, the productivity is improved by 10%.
• Dump height is improved to 3.1m.
• Brand new design of cooling system meets the requirements for -20℃ ~ +43℃ ambient conditions.
• The electric system is upgraded and adopts high grade waterproof and dustproof plugins, which guarantees the safety and reliability.
• Large capacity battery greatly improves the start performance.
• Dual-brake booster design guarantees the safety and reliability of the brake system.
• The overall design meets China’s mandatory noise and safety standards.
