ABSTRACT:
A landing gear for semitrailers includes a two-speed single reduction gear assembly having fewer, smaller, and simpler parts, resulting in a compact single reduction gear assembly and cost efficient landing gear unit with a unique clutch-shifting mechanism to provide for shifting from one ratio to another. The single reduction gear assembly is disposed on and about vertically offset input and output shafts further resulting in an easy to crank and shift landing gear unit capable of achieving standard crank handle turn to vertical leg travel distance ratios. The low gear or low speed ratio of the landing gear unit can be varied within a broad range during manufacture, if desired, generally without increasing the overall size or complexity of the two-speed single reduction gear assembly. The landing gear can further include a universal mounting feature and is durable and simple to use.
