Why the Center of Gravity Matters

If you’ve ever tried to lift a load that suddenly tilts, you know how fast things can go wrong.
The center of gravity (CoG) determines where your lifting point should be placed so that the load stays balanced during a lift.
Get it right, and the load comes up smoothly. Get it wrong, and the load can swing, twist, or even tip, putting both people and equipment at risk.

That’s where our Center of Gravity Calculator comes in. It helps you calculate the horizontal center of gravity for loads with two known weights positioned at fixed distances from a reference point, ideal for beams, containers, and uneven equipment.

How the Calculator Works

The tool calculates the horizontal center of gravity for a load with two weight points — one on the left (Side A) and one on the right (Side B).
Here’s how to use it:

1. Enter the weights for Side A and Side B (in kilograms).

2. Enter the distances from a chosen reference point.

   • Side A is always on the left of the reference point.

   • Side B is always on the right.

   • Use positive numbers only for both distances.

3. Click “Calculate Center of Gravity.”

The tool will instantly tell you where the balance point lies:

• To the Left or To the Right of your reference point (and by how many meters)

• It also displays the total weight and net moment for quick checks.

Important Notes

• The reference point (0,0) can be anywhere you choose, typically a lifting point, a beam end, or the corner of your load.

• Both sides must have non-negative distances from the reference.

• This calculator assumes fixed left/right positioning to keep results consistent.

• The result helps you know exactly where to position your lifting point for balance.

Safety Reminder:
This calculator is for educational and planning purposes only. Always confirm calculations with a qualified lifting engineer or competent person before performing an actual lift.

Why Center of Gravity Calculations Matter

Finding the CoG is a real-world safety step. It helps you:

• Avoid unintended load rotation during lifts.

• Prevent overloading one side of a beam or lifting point.

• Improve stability when rigging with multiple slings or spreader bars.

• Reduce the risk of equipment damage or off-center lifting accidents.

In short: balanced loads mean safer lifts.
