Zusammenfassung:	A drive system (46) for a telescoping boom (22) includes an elongated member (48), a locking head (50) configured to be driven on the elongated member, an actuator (52) configured to drive the locking head on the elongated member, and a cabling assembly (54) interconnected between the actuator and the locking head such that the locking head is driven on the elongated member in response to operation of the actuator, the cabling assembly including a cable (64) and a plurality of sheaves (66, 68). The telescoping boom includes a base section (34) and one or more telescoping sections (36, 38, 40) configured for telescoping movement relative to the base section, and the locking head is configured to selectively engage and disengage a telescoping section of the one or more telescoping sections.
