Automated jackstand systems and methods deploy a jackstand to support a front end of a trailer parked at an automated loading dock. The jackstand prevents collapse of the trailer's landing gear and prevents upending of the trailer during loading and unloading. Advantageously, by deploying the jackstand automatically, presence of personnel in the yard where tractors and trailers are moving is not required.

A main body including a front portion and a rear portion; a ground engaging device configured for rotation about a substantially horizontal axis A; a drive member for driving the at least one ground engaging device; and a transmission member operably connected to the drive member and the ground engaging device for transmitting drive from the drive member to the ground engaging device for rotating the device about the axis A; wherein the axis A lies on a substantially vertical plane X, said plane X positioned between the front portion and the rear portion; and wherein the drive member is positioned in the rear portion of the main body.
