Landing gears for semi-trailers or the like are disclosed in which the telescoping outer and inner legs of the landing gear are formed as a pair of identical, generally U-shaped sheet metal members which are welded along overlapping seams to form generally box sections. The inner legs are formed with vertical inwardly indented corrugations formed in the end and side walls thereof for added strength. In another embodiment, the outer leg is also formed with corrugations which interfit within the corrugations formed in the inner leg.

Semi-trailer landing gear

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.
