Abstract
A mast assembly including a locking actuator for locking a cradle of the mast in position. The locking actuator includes a housing having a first lock pin extending in a first direction and a movable member supported by the housing having a second lock pin extending in a second direction opposite the first, the locking actuator being slideably mounted to the cradle for sliding movement along an axis parallel to an axis of extension/retraction of the locking actuator. When the locking actuator is extended the first and second lock pins are inserted into respective lock holes in a base member thereby locking the cradle against pivoting movement relative to the base member.
