| Displacement | 6.37 L | 389 cu in | Robust displacement for consistent torque |
| Cooling System | Pressurized | Pressurized | Heavy-duty industrial radiator |
2. Weight, Capacities & Logistics Dimensions
These dimensions are critical for logistics planning, including ocean container stuffing (often requires track/blade breakdown) or RORO (Roll-On/Roll-Off) freight calculations.
| Parameter | Metric System | Imperial System | Shipping & Logistics Relevance |
| Operating Weight | 12,800 kg | 28,219 lbs | Standard configuration with cab/bucket |
| Transport Length | 7,610 mm | 24.97 ft | Standard shipping boom-down position |
| Transport Width | 2,490 mm | 8.17 ft | Optimized for standard flat-rack loading |
| Transport Height | 2,800 mm | 9.19 ft | Top of cab shipping clearance |
| Fuel Tank Capacity | 240 L | 63.4 gal | High-capacity tank for extended field time |
| Hydraulic Tank Cap. | 135 L | 35.7 gal | Core fluid reservoir volume declaration |
3. Hydraulic & Digging Performance
The 312C utilizes a traditional, high-pressure mechanical hydraulic system. This design provides direct, tactile operator feedback and is renowned for ease of service in remote regions.
| Parameter | Metric System | Imperial System | Field Performance Indicator |
| Max System Flow | 228 L/min | 60.2 gal/min | Dual variable-displacement piston pumps |
| Operating Pressure | 30,500 kPa | 4,424 psi | Main implement relief circuit threshold |
| Swing Speed | 11.5 rpm | 11.5 rpm | High-torque rotation for rapid cycling |
| Bucket Breakout Force | 89.0 kN | 20,000 lbf | Strong penetration for 13-ton class |
| Stick Digging Force | 67.0 kN | 15,060 lbf | Reliable trenching and lifting force |
4. Undercarriage & Mobility
Built on a proven X-frame chassis, the 312C offers excellent side-slope stability and long-term durability in abrasive soil conditions.
| Parameter | Metric System | Imperial System | Underfoot Mobility |
| Standard Shoe Width | 500 mm | 20 in | Triple grouser standard track pads |
| Max Travel Speed | 5.5 km/h | 3.4 mph | Dual-speed auto-shift travel drives |
| Max Traction Force | 118 kN | 26,530 lbf | Robust drawbar pull for backfilling/climbing |
| Ground Pressure | 38.0 kPa | 5.51 psi | Low-impact footprint for soft ground |
5. Professional Logistics Note
The CAT 312C remains one of the most sought-after assets in the secondary international market due to its “mechanical-first” design. Lacking complex emission after-treatment and extensive electronic control modules, it is an ideal choice for operations in Africa, the Middle East, and Southeast Asia. Its global availability of spare parts (both genuine and high-quality aftermarket) ensures a low total cost of ownership and high resale liquidity for international traders.
