1. A lifting and lowering tool comprising:
a foot configured to be supported on a surface;
a bar extending from the foot; and
a movable assembly comprising:
a housing;
a movable platform 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;
wherein the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator; and
wherein the release actuator and the lowering actuator extend from a common face of the housing, with the release actuator above the lowering actuator relative to the foot, and the lowering actuator is further extended from the common face than the release actuator.
