Key Outcome: 40% reduction in thermal shock failures vs. MY2024 baseline; validated in Middle East desert trials (55°C ambient).

---

2. PRE-DELIVERY INSPECTION (PDI) PROTOCOL

All EoW units undergo a 17-point PDI checklist prior to customer handover. Non-compliance halts shipment. Critical checks for rough-terrain reliability:

2.1 Chassis & Undercarriage Verification

• Frame Alignment: Laser measurement of kingpin-to-axle centers (max. deviation: ±1.5mm).
• Suspension Integrity: Dynamic load test (5,000 kg payload) on 15° articulation; verify no binding in oscillation joints.
• Wheel Hub Torque: Retorqued to 1,850 Nm (±5%) after 50-hr simulated operation.
• Crack Detection: Dye penetrant inspection on high-stress nodes (e.g., boom pivot brackets, rear axle mounts).

2.2 Engine & Hydraulic System Validation

• Cold Start Verification: -25°C simulated start; monitor oil pressure stabilization (<8 sec to 25 psi).
• Hydraulic Pressure Bleed Test: Hold 10% above rated pressure (38 MPa) for 10 min; zero leakage at fittings.
• Coolant Flow Rate: Verified at 180 L/min @ 2,200 RPM (infrared thermography confirms uniform radiator temp).
• Exhaust Gas Analysis: NOx ≤ 0.2 g/kWh; particulate matter ≤ 0.01 g/kWh (under ISO 8178-C1 cycle).

2.3 Rough-Terrain Functional Test

Conducted on SEA LION’s proprietary proving ground (2.5 km mixed-terrain circuit):
1. 30° side-slope traversal (loaded/unloaded) – monitor frame twist via strain gauges.
2. 400-mm vertical obstacle negotiation at 8 km/h – verify suspension travel limits.
3. Continuous 15° grade climb/descent (6 cycles) – engine torque response logged.
Pass Requirement: Zero structural anomalies; hydraulic system temp rise ≤ 15°C.

---

3. OPERATIONAL IMPACT FOR FLEET MANAGEMENT

• Chassis Longevity: Field data indicates 12,500+ operational hours before structural refurbishment (vs. industry avg. 9,200 hrs).
• Engine Uptime: 98.7% mission readiness in 12-month fleet trials; mean time between overhauls (MTBO) extended to 18,000 hrs.
• PDI Compliance: Units passing full PDI show 63% lower warranty claims in first 500 hours vs. partial-PDI units.

SEA LION ENGINEERING NOTE: Chassis strength and engine durability are non-negotiable in EoW design. Our manufacturing tolerances and PDI rigor ensure operational resilience in quarry, pipeline, and remote infrastructure sites where unplanned downtime incurs >$1,200/hr in lost productivity.
