The clamps are connected by cross braces and include structure to snugly and nestingly engage a tower leg. A method is described using the lifting apparatus to lift a tower subsequent to loosening a nut restraining each tower leg to allow placement of a cushioning pad between a foot of each tower leg and a supporting concrete platform.
