Abstract
A pneumatic monopod hoist that functions as a personal lifting aid. The hoist is light in weight to allow for hand transport and is sized to be used in constrained areas, such as within an aircraft fuselage. The hoist has operating controls located directly upon the housing and may be positioned at varying angles relative to a support surface, such as a floor, to provide optimum load support. The housing and the operating controls are further configured such that the housing can be held in an upright orientation with only a single hand, while the controls are activated with the same hand.
