Over the years I have been lucky enough to have been involved in a few house lifting & moving operations, some heavy overhead rigging operations, and rigged few machines overhead solo. Agreed that is is simple & basic stuff along with basic fundamental safety procedures, knowing & understanding balance points, etc. But, if one does not know how & is not comfortable moving a load, even a 900 load, IMHO, they are wise & prudent not to attempt it. Far lesser loads handled improperly can cause serious injury & damage. A machine will not by much use to the purchaser if an injury obtaining it prevents them from being able to use & enjoy it.
