Abstract
Exemplary operator platform units may include a mounting assembly configured to couple to a conveyor and a drive system assembly coupled to the mounting assembly. The drive system assembly may include a drive assembly and a drive rod configured to be driven by the drive assembly. A platform assembly is movably coupled to the drive system assembly. The platform assembly includes a platform configured to support an operator, and a controller in communication with the drive assembly. The controller is configured to actuate the drive assembly and move the platform relative to the drive system assembly and the conveyor.
