TubeLoad
On-set structural calculator
$3.99 · Designed for iPad. Not verified for macOS.
Calculate deflection, bending moment, stress, and load capacity for aluminium and steel tubes. Built for film-set riggers, scaffolders, and structural designers.
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.
