Calculators

Ground Bearing Pressure Calculator

Calculate ground pressure from equipment weight and track/tire dimensions. Check if your equipment is suitable for soft or sensitive ground conditions.

Pre-filled from: SANY SKT105

Enter track dimensions to calculate ground pressure, or use the custom area option.

Ground Bearing Capacity Guide

Typical Soil Bearing Capacities

  • Peat / Soft clay (wet)< 25 kPa
  • Soft clay / Silt25–50 kPa
  • Firm clay / Loose sand50–100 kPa
  • Stiff clay / Medium sand100–200 kPa
  • Dense sand / Gravel200–400 kPa
  • Rock / Concrete> 400 kPa

Typical Equipment Ground Pressure

  • Compact excavator (2–5t)20–35 kPa
  • Mid excavator (12–25t)35–55 kPa
  • Large excavator (30–50t)50–75 kPa
  • Crawler dozer (15–40t)40–70 kPa
  • Wheeled loader (10–30t)150–300 kPa

Disclaimer: This calculator provides estimates only. Actual ground pressure varies with load distribution, soil moisture, and operating conditions. Always conduct proper geotechnical assessment for critical applications.

Mitigation Strategies

  • 1.Bog mats / Timber mats: Distribute load over larger area, reduce pressure by 50–70%
  • 2.Wider tracks / Low ground pressure tracks: Factory or aftermarket options
  • 3.Temporary roadways: Geotextile + crushed rock or concrete panels
  • 4.Smaller equipment: Consider multiple passes with lighter machine
