BlueCollarSling-angle effect
As the sling angle gets flatter, leg tension rises quickly. Never select rigging from angle math alone.
RIGGERS
Rigging
Sling geometry, load math and rigging reminders. Use the tabs below to switch between working calculators and quick field-reference material.
Field-reference aid. Use approved drawings, current codes/standards, manufacturer data and job-specific procedures for final decisions—especially for lifting, electrical, pressure, fire-protection and life-safety work.
Center of gravity
A load will hang with its center of gravity directly below the hook when free to rotate.
Hardware
Use the manufacturer’s rated capacity, hitch factors, inspection criteria and current rigging plan.
Critical lift note
Calculators are planning aids only; engineered/critical lifts require the approved lift plan and qualified personnel.
