1. A method of lifting a shovel comprising an undercarriage and a superstructure with a counterweight, the method comprising:
configuring the shovel and a lifting system including a front lifting assembly and a rear lifting assembly on a lifting site in a lifting configuration wherein the front lifting assembly comprises a set of front lifting units located under a front portion of the superstructure and between two endless tracks of the undercarriage, and wherein each one of the front lifting units is vertically aligned with a corresponding force applying points on the front portion of an undersurface of the superstructure and the rear lifting assembly comprises a lifting beam including a set of spaced-apart lifting units positioned outwardly of the two endless tracks of the undercarriage and an elongated beam extending inbetween wherein the elongated beam matches corresponding force applying points on an undersurface of the counterweight, wherein a spacing between the lifting units of the rear lifting assembly is greater than a width of the undercarriage;
contacting the front lifting assembly and the rear lifting assembly with the corresponding force applying points on the front portion of the undersurface of the superstructure and the undersurface of the counterweight respectively; and
starting a lifting operation to raise the superstructure to a desired height.
