| Abstract: |
A semitrailer landing gear shoe for reducing pits, cracks, marks and depressions in pavements and extending the lives of pavements at truck terminals and delivery sites. In a first aspect of the invention, the average stress of a landing gear on a pavement is reduced by attaching enlarged plates to existing landing gear shoe with pairs of brackets and pairs of threaded fasteners. Concentrated stresses are reduced by bonding a compressible pad to lower surface of the enlarged plate. In a second aspect of the invention, average and concentrated stresses are reduced by replacing an existing landing gear shoe with a shoe having an enlarged lower portion and a compressible pad bonded or otherwise attached to the lower portion. Alternate constructions for the improved landing gear shoe and the compressible pad are disclosed.
