  • Airplane jack
    Patent number: 8960645
    Abstract: An airplane jack apparatus includes a jack and a strut-cradling jack pad (i.e., SCJP) for lifting a selected flat, spring-steel strut of an airplane landing gear in order to thereby raise the associated main landing gear assembly. Forward and rearward components of the SCJP define diametrically opposite, left-strut-cradling and right-strut-cradling sides of the SCJP. A jack-coupling axle extends between the forward and rearward components along an axle axis of rotation, while a jack-coupling component couples the upper end of the jack to the axle pivotally. As a result, a user can pivot the SCJP about the axle axis of rotation between a left-strut-cradling position of the SCJP, in which the left-strut-cradling side of the SCJP faces upwardly, and a right-strut-cradling position of the SCJP in which the right-strut-cradling side of the SCJP faces upwardly, all without strut-dependent readjustment of the SCJP.
