Driving past a construction site got me looking at the
heavy crane.
Segways are a clever device at staying balanced under
nervous inputs.
<some cellular chemistry>
Can an attachable device be made for craned items so
that they can be quickly stabilised after/while under an
unwanted
motion? A computable angular momentum, as
needed. device. Realtime actors of opposite vector. Of
course the bigger the item, the bigger or more bricks of a
dynamic still are needed.
Quicker production, higher winds. safer.
Let the construction of the immense towers, that have
space for the gentler lift curve engines, begin.

The quicker the attachment/deattachment, the more
realistic this idea is. |

Of course, anything can be done manually with trained
monkeys. |

A Segway Tower Crane would get my vote [+] |

A crane generally lifts via cables. That being the case correcting load swing can't be done without having something to pull against. A crane using a stiff elevator contraption would be able to use a gyroscope as a counter-torque, but that design would be less likely to go wide in the first place. |

I don't think attaching a device to the load would be
effective, but you could program a computer to control all
the dynamic movements of a crane. I would imagine that
the crane operator would designate several pickup-landing
sites and routes between them. The computer could then
make an optimally efficient movement following those
routes, taking into account wind and load. Put some sway
sensors at the top to make sure it doesn't sway any more
than expected based on the load and winds. There will
still be manual control with each lift, for example pulling up
the slack as the load is attached, and easing it to the
ground while a worker spins it to the correct orientation. |

Without something to pull against, it would be hard. But
you probably could program the crane to vision track the
load and dynamically damp moves. Of course you're very
likely to end up with a motion sick operator. |

I was thinking a reaction wheel but because of weight
constraint, swarm drones might be another, better
method. |
