Abstract
An invalid hoist has a wheeled chassis with a rear mounting for an upstanding column and lifting arm. The chassis comprises a cross member with main load-carrying wheels adjacent the ends thereof and three fore-and-aft wheel-carrying arms projecting from the cross member. Two of the arms extend forwardly in spaced relation to leave an opening between them and the third arm extends rearwardly to support the column.
