Abstract
A hoist for lifting and weighing a disabled person comprises a chassis supporting an upstanding column from which a lifting arm projects. The arm can be raised and lowered by means of elevating mechanism associated with the column, and a patient to be lifted, transported and/or weighed can be supported by a patient support member fitted at the end of the arm remote from the column. Weighing means fitted at the top of the column are responsive during weighing to the weight of the arm, including the supported load, at the column.
