Abstract:

A device is provided for hoisting a module for mounting into an overhead space, such as the crown of an aircraft fuselage. The device includes a frame that supports the module, and a lifting device that lifts the first frame to properly place the module. The lifting device includes a frame, attachment devices that attach the frame of the lifting device to overhead support frames, and a driving device that moves the frame of the lifting device up the attachment devices. The frame of the lifting device receives the frame that supports the module as the frame of the lifting device is moved by the driving device.

Abstract:

An engine uplift loader includes a frame assembly having generally parallel first and second frame members spaced apart by a distance enabling the shipping cradle and engine to be positioned between the first and second frame members. A plurality of lifting devices are supported on the frame assembly extending upwardly therefrom, each lifting device being operable to raise and lower an upper end of the lifting device relative to the frame assembly along a generally vertical lifting axis. An attachment assembly is mounted to the upper end of each lifting device, each attachment assembly being structured and arranged to attach to the shipping cradle such that raising the upper ends of the lifting devices causes the shipping cradle and engine to be lifted upwardly. At least one of the attachment assemblies is movably mounted on the respective lifting device such that the attachment assembly can be selectively positioned in various positions relative to the lifting axis of the lifting device so as to accommodate different configurations of shipping cradles. Thus, the engine can be lifted while still in its shipping cradle, and the engine uplift loader can accommodate more than one configuration of engine and cradle.
