Häufig gestellte Fragen

What is the safe load capacity?

It is an estimate of the maximum load the crane can safely lift at a given boom angle and length, based on the rated capacity.

Why does the angle affect capacity?

A higher boom angle increases the vertical component of the lifting force, allowing a greater safe load.

Is this calculator a substitute for professional engineering?

No, it provides a rough estimate. Always consult the crane's load chart and a qualified engineer for actual operations.

Formeln

Die Mathematik hinter diesem Rechner, aufgeschrieben, damit Sie das Ergebnis überprüfen können.

Safe Load Capacity

Safe Load = Rated Capacity × sin(Boom Angle) × (10 / Boom Length)

This formula adjusts the rated capacity based on the boom angle and length to estimate the safe lifting capacity.

Example:

Input: Rated = 50 t, Angle = 60°, Length = 30 m

Calculation: 50 × sin(60°) × (10/30) = 50 × 0.866 × 0.333

Result: ≈ 14.43 tons

Anwendungsfälle im Alltag

Wo diese Berechnung im täglichen Leben vorkommt.

Pre-lift planning

Quickly estimate if a crane can handle a load before consulting the full load chart.

Example: Check if a 20-ton load is feasible with a 50-ton crane at 60° and 30 m boom.

Comparing configurations

See how changing boom length or angle affects capacity.

Example: Compare capacity at 45° vs 60° for the same crane.

Training and education

Help crane operators understand the relationship between angle, length, and capacity.

Example: Demonstrate that capacity decreases as boom length increases.

Tipps und häufige Fehler

Tips

  • Always use the crane's load chart for actual lifts.
  • The formula assumes ideal conditions; real-world factors like wind and ground stability matter.
  • Keep the boom angle within the manufacturer's recommended range.
  • Regularly calibrate crane instruments for accurate angle readings.

Common Mistakes to Avoid

  • Using the rated capacity without adjusting for boom length and angle.
  • Ignoring the effect of boom angle on the horizontal reach.
  • Assuming the safe load is the same for all boom lengths.

Annahmen und Einschränkungen

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
