Six Core Product Advantages
Mature Stable Power Performance
Equipped with world-famous Isuzu four-cylinder diesel engine, it delivers sufficient power reserve and strong low-speed torque. The engine runs stably under continuous excavation work with low fuel consumption. It adapts to long-hour outdoor operation and effectively cuts down overall operating costs.
Compact Body with Flexible Maneuverability
Compact overall dimension and flexible crawler walking design enable the excavator to work freely in narrow lanes, residential areas, farmland and confined construction zones. Small turning radius makes it highly adaptable for urban and rural complex working environments.
Powerful Excavation Capacity
High digging force and optimized working device design ensure excellent performance in trenching, earthmoving and material loading. The standard dozer blade assists in site leveling and backfilling, greatly improving comprehensive working efficiency.
Reinforced Durable Whole Vehicle Structure
Key structural parts including boom, arm, bucket and chassis are made of high-strength wear-resistant steel. Reinforced welding and thickened components effectively resist impact, abrasion and deformation, extending the whole machine service life under harsh working conditions.
Precise Hydraulic Control Experience
Advanced multi-pump combined hydraulic system realizes fast and smooth compound actions. Pilot control handles are light and easy to operate. Operators can master the operation quickly and finish fine excavation and shaping work accurately.
Low Maintenance Cost and Convenient Service
Reasonable component layout and large side opening engine hood make daily inspection, oil replacement and routine maintenance simple and fast. Standard spare parts are widely available worldwide, reducing maintenance difficulty and machine downtime.
