Abstract

A pneumatic system for automatically extending or retracting a semi-trailer's landing gear to support, raise or lower the trailer, such system utilizing a pneumatic gear motor attached to the gear reduction box assembly's inboard shaft through a coupling, allowing axial movement of the inboard shaft, such pneumatic gear motor interconnected to dual air lines selectively activated by a landing gear control, valve receiving air from a valve disposed on the semi-trailer's air brake line.
