Two Point Two Hook Spreader Bar Lift App

This Excel sheet helps you calculate the Lift Point and Sling Loads for a two hook, two point lift using a spreader bar
It calculates the design load, the Dynamic Amplification Factor (DAF), and point loads for slings above and below spreader
It checks the crane lifting capacity, tilt angle, and calculates the lift point load
The resulting forces and angles can be used to design/check the pad-eye for lifting
It also provides an elaborate sling design sheet based on DNV-ST-N-001
Sling Design can be done for Vertical Hitch, Choker Hitch or Basket Hitch
