CROSS SHAFT INNOVATION

A semitrailer is not always parked on even ground, and therefore the loads carried by the two legs of a landing gear are not always equal, and the two legs of the landing gear are not always extending in perfect parallel alignment... Also, when a loaded trailer is raised on its landing gear, the leg on the far side of the crank lags behind the leg on the near side because of the torsion deflection in the cross shaft together with uneven parking surfaces contribute to cause an unbalance in the loads carried by the two legs of a landing legs and a deflection in the frame supporting the landing gear to the trailer... It is believed that when the legs of a landing gear do not extend in a perfect parallel alignment, an axial tension or a compression stress is generated in the cross shaft, causing gear friction inside the telescoping mechanisms of the legs.
