The lifting assembly also includes a winch having a spool, and a cable having a first end attached to the winch and a second end for lifting the electrical switching apparatus. The cable passes over a pivotable, rotatable cable support member mounted upon the support frame to provide even distribution of the cable on the spool. A plurality of wheels rotatable about either a horizontal axis or vertical axes are attached to the support frame for movement of the support frame along the rail members.
