Described is a telescopic lifting arm (1) for self-propelled operating machines (10) comprising three tubular elements (21, 22, 23, 24, 25, 26), with a decreasing cross-section and telescopically connected to each other to define a supporting structure, designed to move between a retracted configuration wherein said tubular elements (21, 22, 23, 24, 25, 26) are inserted one in the other and an elongated configuration wherein two tubular elements are partly extracted. The arm (1) comprises actuator means (5) associated with the tubular elements (21, 22, 23, 24, 25, 26) and configured for actuating two tubular elements (21, 22, 23, 24 25, 26) for pulling them out independently from one other and with different speeds.
