Abstract

A landing gear assembly for a semitrailer includes a pair of legs that may be simultaneously raised or lowered by turning a single crank. Each of the legs is configured to be able to be mounted in either an inboard or outboard configuration. This is achieved by providing both sides of each leg with no protrusions that extend beyond the space provided in the mounting bracket and the mounting hole used to connect the landing gear to the semitrailer. The gear assembly of the landing gear includes a unique floor base that receives and supports the input shaft. A cover is used to support the input ends of the input shaft and the output shaft. The cover is connected to the input side of the upper tube of the leg and allows the gear assembly to be easily assembled within the perimeter of the upper leg.
