Ground Bearing Pressure Formula:
| From: | To: |
Ground Bearing Pressure (GBP) is the pressure exerted by a crane or heavy equipment on the ground surface. It's a critical factor in determining the stability of the equipment and preventing ground failure during lifting operations.
The calculator uses the Ground Bearing Pressure formula:
Where:
Explanation: The formula calculates the pressure distribution by dividing the total weight by the contact area between the crane and the ground surface.
Details: Accurate GBP calculation is crucial for ensuring crane stability, preventing ground settlement or failure, and maintaining safe working conditions on various soil types.
Tips: Enter total weight in kilograms, contact area in square meters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: Why is GBP important for Terex cranes?
A: GBP determines if the ground can support the crane's weight during lifting operations, preventing accidents and equipment damage.
Q2: What are typical GBP values for different soil types?
A: Different soil types have different bearing capacities. Firm ground: 100-200 kPa, soft ground: 50-100 kPa, very soft ground: less than 50 kPa.
Q3: How do I measure contact area accurately?
A: Contact area should include the entire surface area of outrigger pads, tracks, or tires that are in direct contact with the ground surface.
Q4: Does the calculated GBP include safety factors?
A: This calculator provides the theoretical GBP. Actual working conditions may require additional safety factors based on soil conditions and load dynamics.
Q5: When should GBP be recalculated?
A: GBP should be recalculated whenever the crane configuration changes, load weight changes, or when moving to different ground conditions.
