Abstract
A lift device includes a base, a turntable coupled to the base, a boom pivotably coupled to the turntable, and an actuator assembly. The actuator assembly includes a first actuator, a first coupler positioned at a first end of the first actuator, a second actuator, a second coupler positioned at a third end of the second actuator, and a third coupler. The first coupler and the second coupler pivotably couple the first actuator and the second actuator, respectively, to one of the boom or the turntable. The third coupler includes a body and a plurality of arms extending from the body. The body defines (i) a first interface that engages with an opposing second end of the first actuator and (ii) a second interface that engages with an opposing fourth end of the second actuator. The plurality of arms are pivotably coupled to the other one of the boom or the turntable.
