Note:

The Lifting Force per Anchor (Pitching) Calculator is used to determine the lifting force each anchor must bear during the pitching process of precast elements. This calculation is crucial for ensuring safe handling and preventing overloading of anchors, which can lead to accidents.

Parameters Explained:

• Half Weight (G/2) in kN: Half of the total weight of the element during pitching. It must be greater than zero as a zero or negative weight is physically meaningless.
• Lifting Coefficient (f): A factor that accounts for dynamic forces during lifting, typically 1.3. It must be greater than zero as a zero or negative coefficient implies no load or a negative safety margin, which is not applicable.
• Spread Angle Factor (z): A factor based on the spread angle of the lifting cables, typically 1.0 for a 0° 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.
• Number of Anchors (n): The number of anchors supporting the load, fixed at 2 for this calculation.

Key Parameters Table:

Parameter	Value	Description
G/2	25 kN	Half weight during pitching
f	1.3	Lifting coefficient
z	1.0	Spread angle factor (0°)
n	2	Number of anchors

Real-Life Applications:

• Precast Factories: Ensuring safe lifting of precast elements during the pitching process.
• Construction Sites: Handling precast elements during installation.

Importance of Accurate Calculations:

Accurate calculation of the lifting force per anchor is crucial for ensuring the safety and structural integrity of pitching 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 during pitching. By accurately determining the lifting force per anchor, it helps prevent accidents and ensures compliance with safety standards.
