摘要： A material handling vehicle is provided. The material handling vehicle includes a vehicle frame having a drive wheel and an offset wheel arranged under the vehicle frame. The material handling vehicle further includes a rear load wheel assembly pivotally coupled to the vehicle frame via an articulating axle assembly. The rear load wheel assembly includes a first load wheel and a second load wheel. The pivotal coupling between the rear load wheel and the vehicle frame provided by the articulating axle assembly is configured to maintain the drive wheel and the offset wheel in contact with a floor on which the drive wheel and the offset wheel travel.

摘要： A charging system for a material handling vehicle includes a charger plate assembly that is pivotally moveably coupled to a distal end of the mounting assembly arm. The charger plate assembly includes a first electrical contact that is configured to electrically couple with a second electrical contact of a charging port of the material handling vehicle. The charger plate assembly is configured to move relative to the mounting assembly arm when the first electrical contact electrically couples with the second electrical contact, which causes a scrubbing action between the first electrical contact and the second electrical contacts, thereby passively cleaning the contacts.
