CT80-8B3 Excavator Introduction:
The CT80-8B3 Small Excavator redefines compact-class performance with its 8.08-ton frame and 0.32 m³ bucket, engineered to tackle the most demanding mining, construction, and earthmoving projects. Powered by the YANMAR 4TNV98T engine (56.5 kW, 273.7 N·m torque), it delivers industrial-grade force for heavy excavation and material handling, while its dual-pump hydraulic system (158.4 L/min total flow, 27.5 MPa pressure) ensures rapid cycle times and precision control. Crush through rock and compacted soil with 56 kN bucket force and 38 kN arm strength, while reaching heights up to 7.13 m, depths of 4.02 m, and a maximum reach of 6.39 m for large-scale applications. Built for rugged terrain, its reinforced undercarriage (450 mm track shoes, 70% climbing grade) and 39 kPa ground pressure ensure stability on steep slopes and uneven ground, while the 1.87 m tail swing radius maintains agility in confined worksites. Equipped with dual-speed travel (3.6/5.3 km/h) and an integrated dozer blade (330 mm height), it seamlessly transitions between excavation, grading, and backfilling tasks. The ROPS/FOPS-certified cab prioritizes operator comfort with ergonomic controls and panoramic visibility, making the CT80-8B3 the ultimate small excavator for contractors who demand uncompromised power, reach, and versatility in mining, quarrying, and heavy industrial environments.
