Rigging & CG · JobKit

Lift / piece description Date

Distances in feet: type 12.5, 12-6 or 12'-6 1/2". Weights in lbs.

Rigging

Drag the lugs, hook and weights. Shift = fine snap. Arrow keys nudge the selected item.

Hook height above lugs

Load & center of gravity

Each part's weight and CG. X along the piece (same axis as the lugs), Y across it, Z up, from any datum (end A, centerline, bottom). The weights are also the round markers on the drawing.

Item	Weight (lb)	X (ft)	Y (ft)	Z (ft)

Piece outline for the drawing (optional)

Starts at X (ft) Length (ft) Top of piece Z (ft) Depth (ft) Width, for plan view (ft)

Rigging hardware

Pick from the presets or type the WLL off the tag. Leg capacity = the weaker of sling × hitch factor and shackle. Presets are typical WSTDA round-sling and Crosby G-209 shackle ratings — always go by the tag.

Notes

A planning aid, not an engineered lift plan. Critical picks still need the crane chart, rigging certs and the engineer/lift director sign-off your project requires.
