A pin actuator assembly for a telescoping boom includes a locking head having a base, an operating plate operably coupled to the base, one or more cylinder pins and/or one or more section lock arms movable in response to movement of the operating plate relative to the base. The pin actuator assembly also includes an actuator operably coupled to the operating plate and configured to move the operating plate relative to the base. The actuator includes an electric motor and a drive arm. The electric motor is configured to drive the drive arm between an extended drive arm position and a retracteddrive arm position. The pin actuator assembly further includes a motion mitigator having a housing, a rod movable relative to the housing and operably coupled to the actuator, a first biasing member coupled between the rod and the housing; and a second biasing member coupled between the rod and the housing. 一种用于伸缩吊臂的销致动器组件包括锁定头，所述锁定头具有：基部；操作板，其能够操作地联接到基部；一个或多个缸销和/或一个或多个节锁定臂，其能够响应于操作板相对于基部的移动而移动。销致动器组件还包括致动器，该致动器能够操作地联接到操作
