Abstract

Engine loader and transporter apparatus and methods are disclosed. In one embodiment, an engine handling assembly includes a motorized drive assembly engageable with a floor surface, and an engagement unit positioned proximate the drive assembly and partially surrounding a working space. The engagement unit includes a pair of coupling assemblies positioned on opposing lateral sides of the working space that are adapted to be selectively coupleable to the aircraft engine assembly when the aircraft engine assembly is positioned at least partially within the working space. A lifting assembly is operatively coupled to the drive assembly and to the engagement unit and is operable to selectively raise and lower the engagement unit and the aircraft engine assembly with respect to the floor surface.
