RTC Winching Load Calculator
Estimate winching forces
$4.99 · Designed for iPad
New: Stability modelling with CG projection, tipping direction, and real-time safety guidance.
Winching Load Calculator is a professional-grade calculation and planning tool designed for Fire & Rescue, recovery operators, and specialist rescue teams.
Built using real operational formulas, including the official RTC Resistance Card, this app helps you quickly calculate winching loads, mechanical advantage, stabilisation requirements, and safety margins — directly on scene.
Designed to support safer, faster, and more informed decision-making during vehicle recovery and rescue incidents.
