Abstract
A full-gear four-way shuttle, including a two-direction travel servo motor planetary reducer, a jacking reversing servo motor planetary reducer, a jacking reversing gearbox, a jacking reversing drive shaft, a Y-direction travel gearbox and an X-direction travel gearbox. The disclosure also includes a method to operate the full-gear four-way shuttle, in which a jacking reversing servo motor planetary reducer drives a jacking reversing drive shaft to rotate through a jacking reversing gearbox and to move with a cam swing arm; the cam swing arm moves synchronously and drives the full-gear four-way shuttle to move in a reverse direction.
