Abstract

An actuator assembly for a drilling rig includes a cradle actuator coupled to a substructure of a rig, and an actuator bracket having a first end pivotally coupled to the substructure. The actuator bracket is coupled to the cradle actuator. The assembly also includes a cradle having a first end that is pivotally coupled to the actuator bracket and to a first end of a rig-up actuator. The rig-up actuator is receivable at least partially in the cradle. The assembly further includes a front bracket pivotally coupled to the cradle and to the substructure. Extension of the cradle actuator pivots the actuator bracket, the cradle, and the front bracket so as to raise a second end of the rig-up actuator, thereby moving the rig-up actuator from a stowed position to raised position.
