It can be done with cage attachments. There is a two legged lower cage under the base and the legs extend upward past the end of the ram to an attachment point. There is also an upper two legged cage whose legs extend downward from the ram past the base to another attachment point. The two cages are turned 90º from each other so that they can pass by each other as the ram extends. The legs must be long enough for full jack extension before coming together to form the attachment points.
