Balance Crane Simulator (2D)

Side-view tower crane: payload mass, trolley radius, counterweight and wind drive a live load-moment vs counter-moment balance, with tipping risk shown as it happens.

This 2D companion drives the same load-moment vs counter-moment physics as the 3D tower crane through a plain side-view canvas: payload mass, trolley radius, counterweight, hoist height and crosswind combine into a net moment around the tower base, and the crane visibly leans toward whichever side — load or counterweight — currently dominates.

⚙ Under the hood

Load moment = mass × g × radius; counter moment = counterweight × g × fixed arm; wind adds a velocity-squared term. Utilization is the worse of the stability ratio and the rated-capacity ratio at the current radius.
