Semi-Trailer Tandem Slide Estimator

Use a scale ticket and your trailer-specific pounds-per-hole estimate to plan an adjustment before reweighing.

Saved setup values are applied automatically when available.

Always reweigh

Weight transfer per hole varies by trailer geometry, hole spacing and load position. Use a value established for your equipment when possible.

Practical use

Tandem movement is an estimate, not a final scale weight

The amount transferred per hole varies by trailer, suspension, hole spacing and load position. Use the estimator as a starting point, make the adjustment, then reweigh before relying on the new axle weights.
