Abstract
A jack for a vehicle includes a tube configured to be coupled to a chassis, and a cylinder assembly supported by the tube. The cylinder assembly includes a barrel and a rod at least partially received within the barrel. Actuation of the cylinder assembly causes the barrel to move relative to the tube in a first direction parallel to a longitudinal axis of the tube while the rod remains stationary relative to the tube. In some aspects, the jack further includes a locking device selectively received within the tube in a locked position. The locking device intersects the barrel's path to inhibit movement of the barrel in a second direction opposite the first direction when the locking device is in the locked position.
