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 lockinghead 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. 一种用于伸缩吊臂（22）的驱动系统（46），包括：伸长部件（48）；构造成在伸长部件上被驱动的锁定头（50）；构造成在伸长部件上驱动锁定头的致动器（52）；以及线缆组件（54），其在致动器和锁定头之间互连，使得锁定头响应于致动器的操作而在伸长部件上被驱动，线缆组件包括线缆（64）和多个滑轮（66、68）。伸缩吊臂包括基部区段（34）和构造成相对于基部区段伸缩移动的一个或多个伸缩区段（36、38、40），并且锁定头构造成选择性地接合和脱离该一个或多个
