A hoist apparatus for use with a hoist for lifting a load is described. The hoist apparatus includes an elongate load bearing member having a longitudinal axis and at least two support points spaced apart along the longitudinal axis. An intermediate support member includes a hoist connection element for connecting the intermediate support member to a hoist, and at least first and second support point connection elements each connecting the intermediate support member to a respective support point of the elongate load bearing member. The first support point connection element is spaced a first distance from the hoist connection element, and the second support point connection element is spaced a second distance from the hoist connection element. Adjustment means adjusts at least one of the first and second distances so as to adjust the orientation of the longitudinal axis of the elongate load bearing member relative to the horizontal. |
