We build the calculators we needed on site — and give them away. No login, no install, no vendor lock-in. Use them, share them, take them offshore.
The complete lift-planning dashboard we run our own studies on. Sling angle calculator, crane utilisation, offshore DAF, ALARP risk register, rigging register, exportable reports. Free to use.
Every tool below runs entirely in your browser — no server, no data leaves your device.
Sling tension, spreader beam sizing, crane utilisation, and rigging register — engineered inside your browser. Works offline once loaded.
