14 Claims

1. A lifting apparatus for lifting heavy machinery, the lifting apparatus comprising:

first and second lifting devices vertically extendable and spaced-apart from each other, each of the first and second lifting devices comprising a lower portion having a supporting base configured to be positioned on a ground surface, and a beam-receiving portion; and

a transverse lifting beam comprising: a beam body engageable with a portion of the heavy machinery;

and first and second opposed mounting end portions removably engageable with the beam-receiving portions of the first and second lifting devices, for the transverse lifting beam to extend between said first and second lifting devices;

wherein each beam-receiving portion defines a beam-receiving cavity and comprises first and second spaced-apart beam-supporting plates partially delimiting the beam-receiving cavity and extending substantially parallel to each other, wherein each beam-receiving portion includes a beam engagement track defined in at least one of the first and second beam supporting plates of each beam-receiving portion, each of the first and second mounting end portions of the transverse lifting beam being removably engageable with the beam-receiving cavity of the corresponding beam-receiving portion and wherein the beam-receiving cavities of the first and second lifting devices substantially face each other;

wherein said at least one of the first and second beam-supporting plates comprises an inner face and first and second spaced-apart guiding rails protruding inwardly from the inner face, the beam engagement track being at least partially formed between the first and second guiding rails, and wherein said at least one of the first and second beam-supporting plates comprises a beam-bearing portion joining the first and second guiding rails at lower ends thereof.
