    • An invalid hoist comprises a lifting arm 12, a sling hanger support 13 angularly displaceable relative to the lifting arm about a vertical or substantially vertical axis and a sling hanger 14 which is of unitary construction pivotable about a horizontal axis relative to the sling hanger support and which presents two spaced sling attachment points 32 on one side of the horizontal axis and at least one sling attachment point 33 on the other side of the horizontal axis. A rotary drive mechanism 31 is provided for pivoting the sling hanger about said horizontal axis relative to the sling hanger support and switch means are provided for selectively rotating the rotary drive means in one or other of two opposite directions. The sling hanger support is of generally inverted U-shape configuration having a cross member 22 and two parallel or substantially parallel limbs 23 and 24 depending from the cross member. The sling hanger is pivotably connected to the lower ends of the depending limbs and the rotary drive mechanism comprises a power unit 34 supported by the sling hanger support at or adjacent to the cross member and a transmission system 37 connecting the power unit to the sling hanger for pivoting the sling hanger relative to the sling hanger support.
