The Komatsu PC490LC-11 MH (Material Handler) is a heavy-duty, purpose-built variant of the standard 50-ton PC490 excavator class. When equipped with specialized long-front material handling configurations, full heavy-counterweights, and protective structural guarding (often distributed or co-branded in specific regional partnerships such as Lonking’s network in certain markets), its total operational configuration scales up to the 57-ton class.
The full, master technical specifications for the PC490LC-11 MH material handling layout are detailed below.
1. Engine & Powertrain
The heart of the machine is the heavy-duty Komatsu SAA6D125E-7 engine, optimized for steady hydraulic demands during intensive swinging and lifting cycles.
| Parameter | Specification |

| Track Rollers | 8 track rollers & 2 carrier rollers per side |
| Ground Pressure | Approx. 0.65–0.74 kg/cm² (depending on shoe width chosen) |
3. Specialized Material Handling Performance
Unlike a standard digging arm, the MH design utilizes specialized geometric reach profiles optimized for scrap yards, port logistics, and processing feeding.
| Operational Metric | Industrial Rating |
| Maximum Horizontal Reach | 16 to 17 meters (54 to 55 ft) |
| Standard Grapple Capacity | 1.5 m³ (2.0 yd³) |
| Hydraulic Flow Output | 780 L/min (206 US gal/min) |
| Hydraulic Relief Setting | 37.3 MPa (5,400 psi) for implement & travel |
| Swing Speed | 9.0 rpm |
| Swing Torque | 13,414 kg-m (97,024 ft-lbs) |
4. Operational Dimensions & Mobility
| Dimension | Metric / Imperial |
| Max Travel Speed (High) | 5.5 km/h (3.4 mph) |
| Max Travel Speed (Low) | 3.0 km/h (1.9 mph) |
| Transport Length (Approx.) | ~11.93 meters (39.1 ft) |
| Transport Width (Variable Gauge Extended) | Up to 3.49 meters (11.4 ft) |
