A telescoping mast having a latch assembly includes a latch body mountable to a first tube section, a latch mechanism supported by the latch body, a toggle mechanism operatively connected to the latch mechanism, and a latch plate mountable to a second tube section. The latch mechanism includes a pawl member pivotably between an engaged position for interlocking with a corresponding recess in the latch plate to thereby restrict axial movement between the first and second tube sections, and a disengaged position allowing relative axial movement between the first and second tube sections. The toggle mechanism is movable between an over-center locked configuration corresponding to the engaged position of the latch mechanism and an unlocked configuration corresponding to the disengaged position of the latch member.

Toggle latch for sequentially extended mechanical mast

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.
