OUTRIGGER REACTION SIMULATOR

What hits
the ground?

Pick a machine, set the load and radius, and see the estimated worst-case reaction on a single outrigger - then check the resulting ground pressure against your surface and size the right pads or cribbing before the crane shows up.

WORST CASE · BOOM SLEWED OVER ONE OUTRIGGER

The heaviest reaction lands on the outrigger under the boom. Estimated split at this load and radius:

PAD UNDER BOOM5,490 lbs
ADJACENT PADS (EACH)485 lbs
OPPOSITE PAD306 lbs

Reactions rotate with the boom - every pad sees the max as you slew. Crib all four the same.
