1. Changchai 490 High Power Engine & Piston Pump Hydraulic System
Equipped with Changchai 490 water-cooled diesel engine of 34kW high power, sufficient torque for heavy breaking & deep digging without stall. Theoretical fuel consumption 1.8-2L/h, spare parts widely available worldwide. Piston main hydraulic pump delivers large flow & fast response for compound movements, dual pilot joysticks for smooth control. Integral forged hydraulic cylinders with imported Japan NOK oil seals, 4-layer steel wire explosion-proof hoses eliminate leakage during long continuous work, standard independent foot pedal breaker control valve.
2. Wide Heavy-Duty Crawler Travel Gear
Chassis width 1600mm, 230mm track shoe, 1600mm track ground contact length, large ground contact area prevents sinking on muddy construction sites, paddy fields and mountain land. Powerful 35° gradability ensures stable reclamation & steep slope work. Travel speed 3.5km/h for higher transfer efficiency than small tonnage models. Wide thick front dozer blade stabilizes machine while digging and completes backfilling & leveling simultaneously. Integrally stamped thickened chassis, robot fully welded boom & arm with multi-layer built-in reinforcing ribs for excellent impact resistance & anti-deformation under long heavy load.
3. Large Bucket & Wide Working Range For Heavy Earthwork
Standard 540mm digging bucket with 0.1m³ capacity greatly improves single digging volume. Boom length 2060mm, arm length 1180mm. Max digging height 3660mm, max dumping height 2530mm, max digging depth 2600mm with outstanding efficiency for municipal trenching & earth backfilling. Full 360° zero tail swing, counterweight never overhang tracks to avoid scratching walls and saplings in residential zones, factories and narrow sites. Quick coupler enables fast installation of hydraulic breaker, auger drill, log grab and rake for multi-work of digging, rock breaking, drilling & timber grabbing.
4. Open Cabin With Metal Sunshade Canopy
Detachable high-strength metal sunshade roof blocks sunlight and rain during outdoor construction. Open cabin delivers superior ventilation & heat dissipation, suitable for high-temperature summer open-air projects. Thickened shock-absorbing suspension seat reduces fatigue for all-day operation. Full unobstructed viewing window provides clear vision for deep digging & slope work. Overall dimension 370016002240mm, transportable by medium flat trailer as a whole unit to cut logistics cost.
5. Application Scenarios & Export Supply Advantages
