🏗️ Tower Crane Anti-Sway Lab: Hook-Load Pendulum, Input Shaping, Load Chart and Wind

Operate a 3D tower crane that places precast columns, beams, a slab and wall panels. The hook load swings as a pendulum under trolley and slewing acceleration and wind; a load-moment chart and counterweight/ballast balance decide what may be lifted. Verify the pendulum period, the zero-swing ramp time (one pendulum period) and the tipping load against the equations.
