Abstract
An actuator is provided. The actuator includes a housing and a ram linearly movable relative to the housing. The ram is selectively mechanically coupled to a drive screw of the actuator such that in one configuration, the ram is decoupled from the drive screw to allow it to linearly move independently from rotation of the drive screw.
