Enable riggers to safely connect loads to cranes.



To properly identify immediate and potential hazards and prescribe corrective actions.



Reduce employers liability exposure through training and certification.

Rigging Safety 2

Origin and Art of Rigging The earliest rigging was used to raise and lower sails and lift large blocks in the construction of pyramids.

Rigging Safety 3

Definition of Rigging Rigging is part of the lifting operation which forms the link between the crane and the load.

Rigging Safety 4

SAFETY The act or process designed to eliminate risk or danger from an environment.

Standards

Without a standard for straightness, this flag pole could be called straight.

Definition of a standard:

...set up and established by authority as the rule for the measure of quantity, weight, extent, value or quality.

Calculating Sling Loading

Steps: 1. Determine sling angles. (45°) 2. Go to 2-leg bridle capacity column at 45° 3. Select 2-leg bridle with capacity equal to or greater than load to be lifted. (½ inch rope diameter at 3.6 tons)

Rigging Safety

RB 50

56

Calculating Sling Loading

Steps: 1. Determine sling angles. (45°) 2. Select corresponding Load Angle Factor. (1.414) 3. Multiply load weight by Load Angle Factor to get total load on sling legs. (2000 lbs x 1.414 = 2828) 4. Divide total load by the number of sling legs. (2828 lbs ÷ 2 = 1414 lbs per sling leg) 5. Select slings from the single vertical leg column within the sling capacity table.

Rigging Safety

RB 51

57

Calculating Sling Loading

Steps:

1. Divide length by height to get Load Angle Factor. ( 6 ft ÷ 4 ft = 1.5) 2. Multiply Load Angle Factor by load weight to get total load on sling legs. ( 1.5 x 2000 lbs = 3000 lbs) 3. Divide total load by number of sling legs to get load on each sling leg. ( 3000 lbs ÷ 2 = 1500 lbs per sling leg) 4. Select slings from the single vertical leg column within the sling capacity table.
