A hammerhead tower crane builds a 40-storey tower: core pour → steel → floor deck → glass curtain wall. The crane climbs itself with new mast sections as the building grows. Trucks deliver loads to the laydown bays.
| Autopilot | Crane runs pick → slew → trolley → lower → place → return using a task queue, with anti-sway control. Stops in wind > 14 m/s. |
| Manual | You operate the crane. A pulsing ring marks the next load; a cyan marker shows where the carried load goes. |
