ABSTRACT:
An invalid hoist has a lifting arm, a sling hanger support mounted to turn about a rigid vertical bearing axis at the outer end of the arm and a sling hanger which is a unitary construction pivotable about a horizontal axis relative to the sling hanger support. The sling hanger presents spaced sling attachment points on both sides of the horizontal axis for connection of one pair of sling attachments to one side of the horizontal axis and for connection of a second pair of sling attachments to the opposite side of the horizontal axis. Thus the disposition of a sling-suspended invalid can be changed, while suspended on the hoist, by pivotal movement of the sling hanger about the horizontal axis.
