How to run the shift

Bring the hook over the load, lower it, let it settle, then hook on. Ease the levers on and off — a load that is already swinging will not settle in a hurry. Land it inside the green ring with the swing off it, then release.

Desktop: A/D slew · W/S trolley · Q/E hoist · Space hook on / land · C camera · M sound. Phone: left stick slews and trolleys, right stick hoists, drag the scene to look around.

What the game is modelling

  • Radius beats weight. The rated capacity falls away as the trolley runs out. The moment limiter cuts outward trolley and hoist when you exceed it.
  • The load is a pendulum. Accelerating the slew or trolley drives it; stopping does not stop the load. Anti-sway is all in the lever technique.
  • Wind acts on sail area, not mass. The stillage and the precast panel behave nothing alike in the same gust.
  • Shape changes everything. A round load rolls, an uneven load hangs off level and swings unevenly, and a load over half the crane's capacity has to stay in close.
  • Never over people, never released in the air. Both are scored as incidents.

The four loads mirror the load types named in the performance evidence for CPCCLTC4001 Licence to operate a tower crane — a load over half the crane's capacity, a stillage of scaffolding standards, an uneven load and a round load — each moved through at least a 90° slew.

The capacity chart and the wind limit in this game belong to this fictional training crane and this fictional site. Always work to the chart on the machine you are operating and your own site's procedures. A tower crane licence is assessed on full-scale plant with an accredited assessor — never on a simulator.
