Abstract
A lifting apparatus for lifting a tank car is provided. The lifting apparatus can include a first arm to surround and not contact a tank car jacket and a second arm to surround and not contact the tank car jacket.
Claims36
A lifting apparatus for lifting a railroad tank car, comprising:
- a first beam having a first end suspended above the tank car and a second end coupled to a tank car bolster, the first beam having a first shape along a first the length of the first beam from the first end to the second end such that the first beam surrounds and does not contact a tank car jacket;
- a second beam having a first end suspended above the tank car and a second end coupled to the tank car bolster, the second beam having a second shape along a second length of the second beam from the first end to the second end such that the second beam surrounds and does not contact the tank car jacket;
- and
- a third beam connected to the first end of the first beam and the first end of the second beam.

A lifting apparatus for lifting a railroad tank car, comprising:
- a first rigid arm having a first end suspended above the tank car and a second end coupled to a tank car bolster, the first rigid arm having a a first shape such that the first rigid arm surrounds and does not contact a tank car jacket;
- and
- a second rigid arm having a first end suspended above the tank car and a second end coupled to the tank car bolster, the second rigid arm having a second shape such that the second rigid arm surrounds and does not contact the tank car jacket.
A lifting apparatus for lifting a railroad tank car having a top side, a left side, and right side, comprising:
- a curved rigid beam structure surrounding the top side and at least a portion of the left side and right side of the tank car, but not contacting the tank car, the curved rigid beam structure having a first end on a first side of the tank car and a second end on a second side of the tank car, the curved rigid beam structure comprising:
- a left side support extending downward from the curved rigid beam structure, and having a first end rotatably coupled to the first end of the rigid beam structure and a second end configured to couple to the left side of the tank car bolster, and
- a right side support extending downward from the curved rigid beam structure, and having a first end rotatably coupled to the second end of the rigid beam structure and a second end configured to couple to the right side of the tank car bolster.
A lifting apparatus for lifting a railroad tank car, comprising:
- a first rigid beam segment having a portion suspended above the tank car, the first rigid beam segment having a first end and a second end;
- a second rigid beam segment extending downward from the first end of the first rigid beam segment, the second beam segment having a distal end configured to be coupled to the tank car, the second beam surrounding but not contacting the tank car;
- and
- a third rigid beam segment extending downward from the second end of the first rigid beam segment, the third beam segment having a distal end configured to be coupled to the tank car, the third beam surrounding but not contacting the tank car,
- wherein the first rigid beam segment, second rigid beam segment, and third rigid beam segment are configured to form a rigid frame.

A method for lifting a railroad tank car having a top side, a left side, and right side, comprising:
- positioning a lifting apparatus above the tank car, the lifting apparatus comprising:
- a first rigid beam segment suspended above the tank car and surrounding the top side without contact the tank car, the first rigid beam segment having a first end and a second end;
- a second rigid beam segment extending downward from the first end of the first rigid beam segment, the second beam segment configured to couple to the left side to the tank car, the second beam surrounding but not contacting the tank car;
- and
- a third rigid beam segment extending downward from the second end of the first rigid beam segment, the third beam segment configured to couple to the right side of the tank car, the third beam surrounding but not contacting the tank car,
- wherein the first rigid beam segment, second rigid beam segment, and third rigid beam segment are configured to form a rigid frame.
