Note:
The Load per Anchor During Transport Calculator is used to determine the load each anchor must bear during the transportation or mounting phase of precast elements. This calculation is vital to ensure safe handling and prevent overloading of anchors, which can lead to catastrophic accidents and structural failures.
Parameters Explained:
- Weight (G) in kN: The total weight of the element being transported. It must be greater than zero as a zero or negative weight is physically meaningless. A negative weight implies a force pulling the object upwards, which is not applicable in this lifting scenario.
- Lifting Coefficient (f): A factor that accounts for dynamic forces during lifting, typically 1.3 for transportation. It must be greater than zero as a zero or negative coefficient implies no load or a negative safety margin, which is not applicable. A negative coefficient would suggest a lifting operation that reduces load, which is not physically sensible.
- Spread Angle Factor (z): A factor based on the spread angle of the lifting cables, typically 1.16 for a 30° spread angle. It must be greater than zero as a zero or negative angle factor implies no force transfer or an inverted force transfer, which is not physically meaningful. A negative spread angle factor would suggest lifting cables that push inwards, which is not applicable in standard lifting procedures.
- Number of Anchors (n): The number of anchors supporting the load. It must be at least 1, as a zero or negative number of anchors is not possible. A negative number of anchors implies an impossible physical scenario.

Real-Life Applications:
- Construction: Safely transporting and mounting precast concrete elements on-site, such as beams, columns, and panels.
- Manufacturing: Moving heavy machinery and equipment during setup and relocation within a factory or plant.
- Marine Industry: Hoisting heavy loads on ships and docks, including large containers and equipment.
Importance of Accurate Calculations:
Accurate calculation of the load per anchor is crucial for ensuring the safety and structural integrity of transportation and mounting operations. Incorrect calculations can lead to overloading of anchors, which may result in:
- Anchor failure
- Dropped loads
- Structural damage
- Serious injuries or fatalities
Conclusion:
This calculator provides a vital tool for ensuring the safe handling of precast elements. By accurately determining the load per anchor, it helps prevent accidents and ensures compliance with safety standards in various industries.
