Rigging and Load Handling: Lifting Loads Without Dropping Them
A dropped or shifting load kills riggers and crane operators alike. Safe rigging is a calculation, an inspection, and a communication discipline.
QUICK ANSWER
Safe rigging requires knowing the load weight and center of gravity, selecting slings and hardware rated above the load with the correct angle factor, inspecting all gear before use, and clear signaling between rigger and operator. Sling angle dramatically increases tension, so a sling rated for a load lifted vertically can fail at a shallow angle.
Weight, Center of Gravity, and Sling Angle
Rigging starts with the load: how much it weighs and where its center of gravity is. Then the sling angle, a shallow angle multiplies the tension in each leg, so a sling that holds a load vertically can be overloaded at 30 degrees. This math is the difference between a safe lift and a dropped load.
Inspect and Communicate
- Gear inspection: slings, shackles, and hooks checked for wear, cuts, and deformation before every lift.
- Rated capacity: hardware selected above the load including the angle factor.
- Signaling: one designated signal person, clear hand or radio signals with the operator.
Rigging and the Crane
Rigging pairs with crane signaling and connects to struck-by hazards from swinging loads.
WE BUILD THIS IN VR — THE PRIME VR
We build rigging into VR so riggers practice load calculation, sling-angle selection, gear inspection, and signaling on realistic lifts. The scoring layer catches an overloaded sling angle or an unqualified signal, the errors that drop loads.

Why does sling angle matter in rigging? +
As the sling angle gets shallower, the tension in each leg increases sharply. A sling that safely holds a load lifted straight up can be overloaded and fail at a low angle, so the angle factor must be included in every calculation.
What must be inspected before a lift? +
All rigging gear, slings, shackles, hooks, and hardware, checked for wear, cuts, kinks, and deformation. Any damaged component is removed from service before the lift.
Who directs a crane during a lift? +
One designated, qualified signal person communicates with the operator using standardized hand or radio signals, so there is never confusion about who is giving directions.
