SANDSHOE, Abstract of the Disclosure, A sandshoe for a semi-trailer landing gear is formed with an inverted V-shaped support member the, depending legs of which are attached to a bottom platform. The apex of the support member is received within a generally conforming, transversely oriented yoke carried on the bottom of the landing gear, and is attached thereto by bolts as well as by auxiliary retainer clips. The improved sandshoe is relatively light in weight yet provides high strength as compared to conventional sandshoes, in that the arrangement of the support member places the bottom platform in tension in the region between the legs of the support member.
