## What is TubeLoad?

TubeCalc is a fast structural calculator for aluminium and steel tubes, designed for film-set riggers, grips, scaffolders, and anyone who needs to verify load limits in the field.

Four loading configurations:
• Simple — single point load on a simply-supported tube
• Two Loads — two independent loads, anywhere along the span
• Cantilever — fixed at one end, load at the free end
• Boom — overhanging beam with counterweight and adjustable support

Calculates:
• Deflection (with L/120 serviceability limit)
• Bending moment and bending stress
• Maximum safe point load
• Shear force and bending moment diagrams
• Support reactions

Material library includes 6000-series aluminium alloys (6060, 6061-T6, 6082) and structural steel grades (S235–S420) — both EU and US variants.

Other features:
• Adjustable design factor (1:1 to 7:1, or custom)
• Metric and imperial units
• Save tube presets for quick recall across all calculators
• Interactive beam diagrams — drag loads to see live updates
• Works offline

Important: TubeCalc is an engineering aid, not a substitute for a qualified structural engineer. Always have rigging verified for safety-critical applications.
