Product Description
The XE550G is a 55-ton heavy-duty hydraulic crawler excavator built for mining, quarrying, and large-scale earthmoving projects. It combines a high-torque diesel engine, energy-efficient hydraulic system, and reinforced structural design to deliver maximum productivity, durability, and fuel economy under continuous heavy loads. Designed for harsh environments, it ensures stable performance in open-pit mining, rock excavation, and major infrastructure developments.
Product Advantages
Powerful & Fuel-Efficient
Equipped with a high-performance diesel engine (320 kW / 1,800 rpm) meeting international emission standards. Matched with an optimized hydraulic system, it delivers 35 MPa system pressure and strong digging force while lowering fuel consumption by up to 12% vs. conventional models.
Heavy-Duty Reinforced Structure
Boom, arm, and bucket use high-strength wear-resistant steel with precision welding and heat treatment. Heavy-duty undercarriage with reinforced track frame and 600 mm track shoes provides superior stability and long service life in rocky, muddy terrain.
High Digging Performance
Max. digging depth 7,800 mm, max. reach 11,900 mm, bucket capacity 2.5–3.5 m³. Fast cycle times and strong breakout force ensure efficient loading and mass earthmoving.
Intelligent & Comfortable Cab
Ergonomic suspension seat, fully adjustable controls, and large LCD monitor. Soundproof, dust-proof, shock-absorbing cabin reduces operator fatigue during long shifts.
Easy Maintenance & High Reliability
Centralized maintenance points, wide-opening service doors, and extended oil change intervals. Integrated self-diagnosis system quickly identifies faults, minimizing downtime.
Versatile Attachment Compatibility
Supports standard bucket, heavy rock bucket, hydraulic breaker, grapple, ripper, and more—suitable for excavation, demolition, rock breaking, and material handling.

Product Operation Guide
1 .Pre-Operation Inspection
Check machine exterior: boom, arm, bucket, tracks for cracks, deformation, or loose bolts.
Verify fluid levels: fuel, engine oil, hydraulic oil, coolant; check for leaks.
Inspect electrical system: battery connections, lights, horn, and instrument panel.
Check attachments: bucket/breaker pins, bolts, and hydraulic hoses for damage.
Start engine and idle 3–5 minutes; monitor oil pressure, water temperature, and abnormal noise.
2 .Basic Operation
Moving: Left joystick forward = forward; back = reverse; left/right = turn. Slow on uneven ground.
Digging: Right joystick forward = lower bucket; back = lift; left = curl; right = dump. Avoid overloading.
Loading: Lift bucket, swing to truck, align, dump, then return.
Stopping: Park on flat ground, lower bucket to soil, idle 2 minutes, shut off engine, engage parking brake.
3. Safety Precautions
Only trained, certified operators allowed.
No operation on slopes >30°; avoid sudden turns.
Keep personnel clear of swing radius and under boom/arm.
Do not touch hot engine/exhaust parts during or after operation.
Stop immediately if abnormal noise, vibration, or leakage occurs.
