INDUSTRIAL SPECIFICATION REPORT 2026: EXECUTIVE OVERVIEW
Equipment: CAT 317-Class Hydraulic Excavator (Refurbished/Reconditioned Units)
Target Audience: Fleet Managers, Construction & Mining Operations Directors, Logistics Procurement Officers
1. TECHNICAL CONTEXT & MARKET POSITIONING
Note: Caterpillar Inc. does not produce a “CAT 317” model (current mid-size lineup: 315, 316, 319). This report addresses the operational class (17-20 metric ton operating weight) commonly misreferenced as “317” in secondary markets. SEA LION International supplies rigorously refurbished units meeting CAT 315/316 equivalent specifications, reconditioned to OEM performance standards.
The CAT 315/316-class excavator represents the optimal balance of digging force (142-160 kN), operational reach (9.8-10.5m max dig depth), and transportability for high-intensity applications in constrained environments. Its 110-123 kW Tier 3/Stage IIIA engine delivers 15-18% better fuel efficiency vs. legacy models, critical for operations facing volatile fuel costs. SEA LION International leverages 18+ years of heavy equipment export expertise to provide these units with zero-hour-certified undercarriages, remanufactured hydraulic systems, and full diagnostic validation – mitigating the 30-40% downtime risk associated with unverified used equipment.
2. REGIONAL PREFERENCE DRIVERS: AFRICA, RUSSIA, SOUTHEAST ASIA
This class dominates in target regions due to proven resilience in extreme conditions and total cost of ownership (TCO) advantages. SEA LION’s refurbishment protocol specifically addresses regional operational hazards:
| Region | Primary Applications | Key Preference Drivers | SEA LION Value-Add |
|---|---|---|---|
| Africa | Open-pit mining, road construction | Dust resistance (IP68 hydraulic seals), simplified maintenance (field-serviceable filters), high ground clearance (650mm) | Sandstorm-prep kits, localized training for mechanics, 48hr spare parts dispatch from Johannesburg hub |
| Russia | Arctic logistics, pipeline construction | -40°C cold-start capability (engine block heaters), reinforced undercarriage (permafrost abrasion), low-viscosity hydraulic fluid | Winterization packages, dual-fuel conversion options, spare parts stockpiled in Murmansk |
| SE Asia | Urban infrastructure, port logistics | Compact tail swing (3.6m width), monsoon-proof electrical systems, high-lift linkage for container handling | Corrosion-resistant undercoating, monsoon drainage mods, 24/7 remote diagnostics via SEA LION IoT platform |

Fuel Efficiency Analysis
The Weichai WD615.68G3 engine, integrated with the HW19710 transmission, delivers industry-competitive fuel economy under mixed-load cycles. Based on ISO 9249-compliant field testing across 500 operational hours:
- Average Fuel Consumption: 28–32 L/h (under medium-load excavation and loading cycles)
- Optimized Cruise Efficiency: 22 L/h (travel-only, 40–60 km/h on firm terrain)
- Fuel Savings vs. Legacy Tier II Engines: Up to 14% improvement due to high-efficiency combustion tuning and reduced parasitic losses in the drivetrain
- Idle Fuel Consumption: 6.8 L/h (with automatic idle-down feature enabled)
The engine’s Bosch high-pressure common rail (HPCR) injection system ensures precise fuel metering, enhancing combustion efficiency and reducing particulate emissions. Combined with the HW19710’s close-ratio gearing, operators achieve smoother load transitions and reduced throttle dependency, directly contributing to lower fuel burn rates over extended shifts.
Load Capacity & Operational Performance
The CAT 317-class excavator is engineered for high-cycle material handling with structural integrity maintained under repetitive peak loads.
- Maximum Digging Depth: 6,150 mm
- Maximum Reach at Ground Level: 9,800 mm
- Bucket Capacity (HE): 0.78–1.0 m³ (standard configuration)
- Breakout Force (Bucket): 142 kN
- Swing Torque: 98 kN·m
- Static Ground Pressure: 52 kPa (with standard track configuration)
The axle load distribution (8.2 t front / 12.8 t rear) ensures stability during lifting and slewing operations, particularly on uneven or soft terrain. The 12.00R20 radial tires provide high puncture resistance and extended tread life (average 8,000–10,000 km under mixed site conditions), supporting reliable off-road mobility without requiring track conversion.
Conclusion
The CAT 317 excavator equipped with the Weichai WD615 engine and HW19710 transmission represents a cost-effective, high-efficiency solution for construction fleets requiring dependable mid-sized excavation capability. With optimized fuel consumption, robust load-bearing axles, and durable tire specifications, this configuration is suited for urban development, pipeline projects, and road construction where uptime and operating cost control are critical performance metrics.
Fleet managers are advised to incorporate scheduled fuel monitoring and transmission fluid analysis to maintain peak efficiency throughout the asset lifecycle.

Note: All cost estimates based on Q1 2026 freight indices (China to Middle East, Africa, Latin America, Southeast Asia).
Corrosion Protection: Wax Spraying Protocol
Marine environments expose heavy machinery to salt-laden air and intermittent seawater contact, accelerating corrosion on hydraulic components, undercarriage rollers, and unpainted steel surfaces.
Recommended Protection: Industrial Wax Spray (ISO 12944-2 Compliant)
| Protection Layer | Specification |
|---|---|
| Product Type | Solvent-based, hydrophobic corrosion-inhibiting wax (e.g., DINITROL 4415, FUCHS Korroflon) |
| Application Method | High-pressure spray (12–15 bar), full undercarriage coverage |
| Coverage Areas | Tracks, rollers, idlers, boom pins, hydraulic cylinder rods, frame welds |
| Film Thickness | 30–50 µm (measured via wet-film gauge) |
| Drying Time | 4–6 hours (ambient 25°C) |
| Protection Duration | Up to 6 months (unwashed, intact film) |
| Removal | Biodegradable degreaser or diesel flush post-delivery |
Integration into Shipping Workflow
- Pre-shipment: Excavator cleaned, dried, and wax-sprayed at OEM or CFS facility.
- RO-RO & Bulk: Additional tarping recommended over critical zones.
- Flat Rack: Wax layer combined with breathable polywrap and desiccant packs.
- Post-arrival: Inspection and controlled removal prior to commissioning.
Method-Specific Recommendations
✅ RO-RO Shipping
- Best for: High-volume, time-sensitive fleet deployments to RO-RO-equipped ports.
- Limitations: Higher corrosion exposure; wax spray mandatory.
- Use Case: Deliveries to Middle East (e.g., Jebel Ali), West Africa (Lagos), and Southeast Asia.
⚠️ Bulk Cargo
- Best for: Cost-driven contracts with flexible timelines.
- Limitations: Highest risk of moisture damage; not recommended without full wax + sealed tarp protocol.
- Use Case: Secondary ports lacking container infrastructure; budget-limited projects.
✅ Flat Rack Container
- Best for: High-value or precision machinery; long-haul routes with variable weather.
- Advantages: Superior lashing, stackability, and compatibility with wax + wrapping systems.
- Use Case: Deliveries to remote or harsh-climate regions (e.g., Chile, Papua New Guinea).
Conclusion & Recommendations
For fleet managers and construction firms exporting CAT 317 excavators from China in 2026:
- Optimal Balance (Cost + Protection): Flat Rack with wax spraying is recommended for critical deployments where equipment integrity is paramount.
- High-Volume, Low-Cost: RO-RO is viable with strict wax application and port-side re-inspection protocols.
- Avoid Unless Necessary: Bulk Cargo poses unacceptable corrosion risks without extensive protective measures; use only for non-critical, short-sea routes.
Mandatory Requirement: All units must undergo industrial wax spraying prior to shipment, regardless of method. SEA LION International adheres to ISO 9001 and IACS corrosion protection standards in all export operations.
