There is disclosed a lifting apparatus and a method for lifting a shovel including its upper part (01), its lower part (02) and its boom (07) while the shovel handle (09) and dipper (10) remain on the ground. The lifting system may comprise six lifting devices arranged in three pairs that are disposed under the shovel on three lines: front, middle and rear (ref. figure 10), the rear line being under the shovel counterweight. The lifting system is connected to a power and control unit (26) from which, through the use of a programmable logic controller (29) and level detectors (48, 49), metered hydraulic power is selectively applied at each lifting point in order to raise the shovel to a desired height while in doing so maintaining it level with a pre-set lifting plane throughout the entire operation.
