1. A trailer for lifting a heavy load, the trailer comprising: a base frame defining an opening for receiving the heavy load upon displacement of the trailer toward the heavy load;a structural frame upwardly extending from the base frame, the structural frame including a lifting frame, wherein in us
1. A trailer for lifting a heavy load, the trailer comprising: a base frame defining an opening for receiving the heavy load upon displacement of the trailer toward the heavy load;a structural frame upwardly extending from the base frame, the structural frame including a lifting frame, wherein in use the lifting frame is positioned at least in part above the heavy load and from which the heavy load is removably attached, the lifting frame further comprising vertical members configured for movably engaging the structural frame; anda lifting device for controlling a position of the lifting frame for vertically lifting or lowering the heavy load while it is removably attached to the lifting frame and thereby to permit displacement of the heavy load with the trailer, the lifting device further comprising sliding adaptors through which the vertical members are free to slide, each of the sliding adaptors comprising a hole, the lifting device further comprising pins, each one of the pins for insertion respectively in the hole in each one of the sliding adaptors thereby locking the sliding adaptors with their respective vertical members, wherein the vertical members of the lifting frame movably extend from the structural frame, through the sliding adaptors, for adopting a plurality of vertical lifting positions relative to the structural frame. 2. The trailer of claim 1, wherein the lifting frame includes a corresponding mating connector downwardly extending towards the heavy load for removably engaging with a mating connector of the heavy load when positioned within the base frame. 3. The trailer of claim 2, wherein the lifting device is located between the structural frame and the lifting frame for lifting the lifting frame from one of the plurality of vertical lifting positions to another one of the plurality of vertical lifting positions, thereby lifting the heavy load over the base frame. 4. The trailer of claim 2, wherein the corresponding mating connector of the lifting frame is movable and adjustable to engage with the mating connector of the heavy load in a vertical relationship. 5. The trailer of claim 4, wherein the corresponding mating connector comprises an extending section being perpendicular to and downwardly extending from a horizontal lifting member of the lifting frame, the extending section comprising a plurality of holes, the corresponding mating connector further comprising a strap extending from one of the plurality of holes for engaging with the mating connector of the heavy load. 6. The trailer of claim 1, wherein at least one of the vertical members comprises a plurality of holes, and wherein one of the plurality of holes in the vertical members and the hole in each one of the sliding adaptors are defined for receiving the pin for lifting the lifting frame and a part of the lifting device in one of the plurality of vertical lifting positions relative to the structural frame. 7. The trailer of claim 1, wherein the heavy load defines a width W1 and wherein the opening defined by the base frame defines a width W2 greater than the width W1. 8. The trailer of claim 1, wherein the base frame defines a longitudinal plan and the structural frame defines a vertical direction and wherein the vertical direction of the structural frame is substantially perpendicular to the longitudinal plan of the base frame. 9. The trailer of claim 1, further comprising a removable supporting section removably engaged with the base frame for supporting the heavy load after lifting of the heavy load. 10. The trailer of claim 9, wherein the removable supporting section comprises a plurality of primary transversal bars engaged with the base frame and a plurality of secondary transversal bars perpendicularly removably fixed to the plurality of primary transversal bars. 11. The trailer of claim 1, wherein the base frame further comprises skis for displacing the base frame in a lateral direction. 12. The trailer of claim 1, wherein the base frame further comprises a brake system opposite to the opening defined by the base frame for braking the base frame. 13. The trailer of claim 12, wherein the brake system comprises a plurality of rigid elements extending downwardly from the base frame. 14. The trailer of claim 12, wherein the lifting frame, the base frame and the structural frame define a squared cross-sectional area. 15. The trailer of claim 1, wherein the lifting device further includes a jack having a bottom end and pushing end, a jack supporting section for supporting the bottom end of the jack, and a jack pushing section for interfacing with the pushing end of the jack. 16. The trailer of claim 15, wherein the jack supporting section extends from the structural frame. 17. The trailer of claim 1, wherein the lifting device further comprises a vertical lifting bar extending between two of the sliding adaptors. 18. The trailer of claim 17, further wherein the lifting device comprises at least one of a hydraulic lifting device. 19. The trailer of claim 18, wherein the lifting device is in contact with the vertical lifting bar and pushes thereon. 20. A method for lifting a heavy load defining an external surface and a mating connector on the external surface, the method comprising the steps of: displacing a lifting frame toward and above the heavy load, the lifting frame comprising vertical members removably extending from a structural frame, the structural frame extending from a base frame defining an opening for receiving the heavy load when displaced in a lateral position relative to a ground surface;removably engaging a corresponding mating connector of the lifting frame with the mating connector of the heavy load when positioned within the base frame;lifting the heavy load equal to or above a level defined by the base frame, the lifting comprises: placing a pin in a hole of each of a plurality of sliding adaptors and a corresponding one of a plurality of holes in each of the vertical members thereby locking the sliding adaptors with the lifting frame, the sliding adaptors having a vertical lifting bar extending therefrom and wherein the vertical members of the lifting frame movably extend from the structural frame, through the sliding adaptors, for adopting a plurality of vertical lifting positions relative to the structural frame; andoperating jacks to lift the vertical lifting bar thereby also lifting the vertical members and the heavy load in the vertical direction until one of the holes within each of the vertical members is aligned with a respective hole in the structural frame and until the heavy load is at a desired height to permit the installation of a supporting section; andremovably engaging the supporting section with the base frame for supporting the heavy load when the lifting frame adopts one of the plurality of lifting positions.
