OK Bob,
I concede, yes, in no way does operating a forklift, compare with a crane.
However, it is up to the operator of either machine as to what is carried with it.
So we are clear this is the type of machine I mean.
Oh yeah, not a worry there mate!.
The signals you would use controlling a fork lift are pretty basic. No winches or rotation etc.
I uesd to have a wall-chart at work that gave all the common signs and hand gestures used for both cranes and forklifts, one of the night-shift people pinched it!.
