Zusammenfassung:	A lifting and lowering tool system includes a lifting and lowering tool (2520) and a support extension (2510). The lifting and lowering tool includes a foot (2555) configured to be supported on a surface; a bar (2550) extending from the foot; and a movable assembly (2540). The movable assembly includes a housing (2530); a movable platform (2570) shaped to support a load thereon; a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot; a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot; and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. The support extension (2510) is configured to support a load thereon and is further configured to couple to the lifting and lowering tool such that movement of the movable assembly along the bar raises or lowers the support extension.
