Abstract

A lift device includes a base having a first end and an opposing second end, a first arm pivotally coupled to the first end, a second arm pivotally coupled to the first end, a third arm pivotally coupled to the opposing second end, a fourth arm pivotally coupled to the opposing second end, and a leveling assembly. The leveling assembly includes a first actuator extending between the first arm and the first end, a second actuator extending between the second arm and the first end, a third actuator extending between the third arm and the opposing second end, a fourth actuator extending between the fourth arm and the opposing second end, and a controller configured to control the first actuator, the second actuator, the third actuator, and the fourth actuator to reconfigure the leveling assembly between (i) a shipping, transport, or storage mode and (ii) an operational mode.
