Abstract
Disclosed is a lifting device and related methods. The lifting device features a housing with at least two arms that each have engagement cams. The lifting device is placed over a tubular object and then the arms are pulled upwards until the engagement cams are in contact with the tubular object. Once in contact with the tubular object, the force from the arms creates a secure hold between the engagement cams and the object, whereby a user can lift the object and move it from one point to another safely and efficiently.
Claims4
A lifting device comprising:
- a tubular housing (101) with at least two slots (103) and two ends;
- wherein the tubular housing is open ended on one end that has received an object;
- wherein the tubular housing is partially open ended on another end, wherein the partially open ended end is further defined by a housing stop (102) that has stopped the object from travelling completely through the tubular housing (101);
- at least two arms (202, 302) that are fastened to the tubular housing (101), wherein the two arms (202, 302) have engagement cams (203, 303) and grips (501),
- wherein the engagement cams (203, 303) are rotatable in and out of the tubular housing (101) and wherein the engagement cams (203, 303) are situated in the tubular housing (101) so that the engagement cams (203, 303) are in contact with the tubular object and so that the arms (202,302) oblique to an axis of the tubular body and the grips (501) disposed at a distal end of the arms (202,302).

A method of moving a tubular object comprising:
- obtaining a lifting device comprising tubular housing (101) with at least two slots (103), wherein the tubular housing is open ended on one end to receive an object, wherein the tubular housing is partially open ended on another end, wherein the partially open ended end is further defined by a housing stop (102) configured to stop the object from travelling all the way through the tubular housing (101), at least two arms (202, 302) that are fastened to the tubular housing (101), wherein the two arms (202, 302) have engagement cams (203, 303) and grips (501), wherein the engagement cams (203, 303) are rotatable in and out of the tubular housing (101);
- placing the open ended end of the tubular housing of the lifting device over the tubular object;
- gripping the grips (501) of the two arms (202,302) and then pulling the arms (202, 302) of the lifting device upward until the engagement cams (203, 303) come into contact with the tubular object and apply a pressing force on the object;
- gripping the grips (501) of the two arms (202,302) and then lifting the lifting device while the tubular object is retained within the tubular housing via the pressing force applied to the object;
- moving while lifted said lifting device and tubular object to a desired destination;
- and
- setting said lifting device and tubular object at the desired destination;
- gripping the grips (501) of the two arms (202,302) and then releasing the arms (202, 302) back down until the engagement cams (203, 303) come out of contact with the tubular object.
