Abstract

A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, 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. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

First claim

What is claimed is:

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.

2. The lifting and lowering tool of claim 1 , wherein
the movable platform is coupled to the housing by a flange;
the movable assembly engages the bar through locking plates that are selectively disengaged from the bar through actuation of the lowering actuator; and
the locking plates extend through the flange.

3. The lifting and lowering tool of claim 1 , wherein the movable platform extends above the bar away from the foot when the movable assembly is adjacent to the foot.

4. The lifting and lowering tool of claim 3 , wherein the movable platform comprises a spreader or a clamp.

5. The lifting and lowering tool of claim 1 , wherein the movable platform extends from the housing and includes a flange extending from the movable platform and surrounding the bar.

6. The lifting and lowering tool of claim 1 , wherein a portion of the housing is between the release actuator and the lowering actuator.
