Dolly for support of aircraft landing gear

A dolly for support of an aircraft's landing gear, comprising:

• a one-piece rigid and planar plate lying in a single plane, said plate including opposing mirror-imaged longitudinal planar sides, each of said planar sides including a first planar portion that is continuous and a second planar portion of spaced-apart fingers contiguous with said first planar portion;
• a longitudinal rigid support disposed at each of said planar sides, each said support including
• a tube of triangular cross-section, said tube having a first leg extending along and rigidly coupled directly to said first planar portion of said plate, a second leg extending along and rigidly coupled directly to said first planar portion of said plate inboard of said first leg and rigidly coupled directly to said first leg, and a third leg consisting of said first planar portion extending between said first leg and said second leg,
• a horizontal member extending along and rigidly coupled to said tube, said horizontal member extending over said fingers, and
• a set of bracing members, each of said bracing members rigidly coupled directly to one of said fingers and said horizontal member;
• a set of casters coupled to each said horizontal member with each one of said casters disposed between two adjacent ones of said fingers;
• one of said casters at each of said sides being spring-biased away from said horizontal member associated therewith;
• and
• a rigid ramp operable to engage said plate, wherein said ramp includes an edge adapted to engage a ground surface.

• a one-piece rigid and planar plate lying in a single plane, said plate including opposing mirror-imaged longitudinal planar sides, each of said planar sides including a first planar portion that is continuous and a second planar portion of spaced-apart fingers contiguous with said first planar portion, said plate having a channel in a surface of said plate that is perpendicular to said planar sides;
• a longitudinal rigid support disposed at each of said planar sides, each said support including
• a tube of triangular cross-section, said tube having a first leg extending along and rigidly coupled directly to said first planar portion of said plate, a second leg extending along and rigidly coupled directly to said first planar portion of said plate inboard of said first leg and rigidly coupled directly to said first leg, and a third leg consisting of said first planar portion extending between said first leg and said second leg,
• a horizontal member extending along and rigidly coupled to said tube, said horizontal member extending over said fingers,
• a bar rigidly coupled to said horizontal member, said bar having openings distributed along a length of said bar, and
• a set of bracing members, each of said bracing members rigidly coupled directly to one of said fingers and said horizontal member;
• a set of casters coupled to each said horizontal member with each one of said casters disposed between two adjacent ones of said fingers;
• one of said casters at each of said sides being spring-biased away from said horizontal member associated therewith;
• and
• a rigid ramp having a tab operable to engage said channel, said ramp including an edge adapted to engage a ground surface.
