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.

A jacking tool capable of achieving up-down fine adjustment is provided, and belongs to the technical field of jacking tools. The jacking tool includes a fixed portion and a lifting portion; the fixed portion includes a base and a guide rod arranged on the base; the lifting portion is provided with a lifting plate, a climbing mechanism, and an adjustment grip for controlling the climbing mechanism; the adjustment grip is pressed to actuate the climbing mechanism, to control the lifting portion and the lifting plate to move up along the guide rod; the lifting portion is further provided with a locking mechanism clamped to the guide rod; the locking mechanism restricts the lifting portion from moving down; the lifting plate is slidably arranged on the lifting portion.

An underground pipe in-situ relocation mechanism including a casement pipe, a lifting member and a lifting member moving device. The casement pipe, having upper and lower ends, is insertable into the soil of the ground alongside of the underground pipe. The lifting member being insertable into the casement pipe, the lifting member having a lifting arm pivotally coupled to an end of the lifting member. The lifting member moving device positioned on the upper end of the casement pipe and coupled to an end of the lifting member opposite the lifting arm. The lifting member moving device being configured to move the lifting member relative to the casement pipe to secure the lifting arm against a bottom of the casement pipe after the lifting arm is extended beyond the lower end of the casement pipe and the lifting arm has pivoted from an aligned position in the casement pipe.

An apparatus for removing a battery cell from a rigid housing containing a plurality of contiguous battery cells. The apparatus bridges the housing with a jack that ratchets up a selected battery cell by attachment to undercuts in the terminals. The jack has a hinged connection between the bridge and a manually operated handle. A user operates the handle to raise a strut interfacing between the bridge and the terminals of the battery cell. Upon removal from the housing the battery cell is refurbished or replaced. The apparatus can be used with a selected battery cell in a grid of battery cells without modification or adjustment due to the position of a particular cell within the grid or due to cells having different heights relative to the top of the housing.

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.
