In order to raise infirm or disabled persons from a sitting to a generally standing position, a hoist comprises a mast, a carrier movable along the mast, and a U-shaped lifting member which is connected at its closed end to an upper end of the mast for pivotable movement about a horizontal axis and which at its open part provides laterally spaced attachment points for the attachment of a body sling. The hoist also includes a U-shaped strut pivotably connected at its closed end to the carrier and at its open part to the open part of the lifting member, and an operating mechanism for raising and lowering the carrier along the mast to thereby move the attachment points along an arcuate path. The operating mechanism is self-locking at any chosen position. Such a hoist is capable of being used for lifting of persons of widely differing heights and builds.
