A mobile elevating work platform includes a chassis, a slew bearing, a turntable, a lift system, and a turntable leveling system. The turntable leveling system is positioned above the slew bearing and supports the lift system. The turntable leveling system includes a baseplate, a bracket, a first actuator, and a second actuator. The baseplate extends above the slew bearing. The bracket is rotatably coupled to the baseplate and is configured to tilt relative to the baseplate about an axis extending parallel with the baseplate. The first actuator is positioned on a first side of the bracket and the second actuator is positioned on a second side of the bracket.

A lift device includes a base assembly, a turntable assembly, and a controller. The base assembly includes multiple base assembly batteries. The turntable assembly is rotatably coupled with the base assembly through a slip ring transmission. The turntable assembly includes multiple turntable assembly batteries. The controller is configured to operate the base assembly batteries to discharge electrical energy to the turntable batteries through the slip ring transmission. The slip ring transmission is configured to both (1) drive the turntable assembly to rotate relative to the base assembly and (2) to electrically and communicably couple electrical components of the base assembly with electrical components of the turntable assembly.

Lift device with split battery pack

A lift device includes a lift apparatus and a base assembly. The lift apparatus is configured to raise and lower an implement assembly. The base assembly is configured to support the lift apparatus. The base assembly includes a deployable operator station transitionable between a deployed position and a stowed position. In the deployed position, the deployable operator station is configured to provide a seating and control arrangement for an operator. In the stowed position, the deployable operator station is substantially sealed from an external environment to limit access to the deployable operator station.
