Claims

A system that lifts and moves an object from one place to another,
a. A partially hollow post having a generally vertical axis;
b. A weight disposed within the strut and defining a strut chamber underneath, wherein the strut chamber can be filled with pressurized fluid; and
c. A weight movement system for moving the weight longitudinally and upwardly with respect to the strut, wherein the weight movement controls pressure inside the strut to selectively position the weight along the strut System,
d. A side arm pivotally coupled to the post for rotation about the vertical axis, the longitudinal proximal end near the post and the longitudinal distal far from the post The lateral arm having ends;
e. A cable having one end attached to the weight and the other end attached to the distal end of the side arm;
f. A carriage coupled to the cable and mounted on the side arm;
g. An object attachment member coupled to the cable for attachment of the object;
When the weight is moved downward with respect to the column under gravity, the object is lifted by the cable, and the weight is moved upward with respect to the column under the pressurized fluid in the column inner chamber. A system in which the object is lowered when

2. The system of claim 1, wherein one end is removably attached to the column and the other end has at least one elongated support secured to the side arm. .

2. The arm coupling system attached to the proximal end of the side arm for pivotally coupling the side arm to the support column about the vertical axis. The system described in.

The system according to claim 1, wherein the side arm is coupled to the column so as to be able to rotate 360 ° around the side arm.

The system of claim 1, wherein the weight movement system includes a valve connected to the strut chamber to control the pressure of the strut chamber.

The system according to claim 5, wherein the valve is attached to a lower end in a longitudinal direction of the support column.

The system of claim 6, wherein the valve is connectable to a source of pressurized fluid for selectively raising the pressure in the strut chamber.

The system of claim 7, wherein the pressurized fluid is compressed air.

The system according to claim 8, wherein the pressure in the strut chamber is 30 Pa or less.

The system according to claim 1, wherein the weight is used as a piston and a sealing element is provided between the weight that is the piston and the support column.

The sealing element has an opening therethrough that directs the pressurized fluid away from the strut inner chamber so as to at least partially reduce the frictional force between the weight and the strut. 11. The system of claim 10, having a predetermined area that allows flow through the opening.

The system of claim 1, wherein a rail is coupled to the side arm, and the carriage is freely movable along the rail.

13. The carriage according to claim 12, wherein the carriage is configured to maintain a constant distance between the object mounting member and the carriage when the carriage moves along the rail. system.

14. The system of claim 13, wherein the carriage has a plurality of cable pulleys mounted on the carriage so as to be pivotable and to which the cables are coupled.

The system according to claim 1, wherein the side arm extends in a direction orthogonal to the support column.

The system of claim 1, wherein the side arm is coupled to the strut for infinite continuous rotation about the vertical axis.

The end of the support body detachably coupled to the support column is attached to the support column so as to move in a tangential direction around an axis perpendicular to the support column. system.

A rolling block in which one end removably coupled to the support column of the support body is rotatably engaged with the support column so as to rotate in a tangential direction around the vertical axis with respect to the support column. The system of claim 17, wherein the system is attached to the system.

14. The system of claim 13, wherein the carriage has two rollers that engage the rail, and the two rollers are arranged coaxially with each other.

15. The system according to claim 14, wherein the carriage has two cable pulleys on which the cables are hung, and the two cable pulleys are arranged so as to be coplanar with each other.
