Abstract
A tugger cart includes a tugger frame having a first side member, a second side member, and a locking member disposed in between the first side member and the second side member. A first roller assembly is coupled to an inner surface of the first side member and a second roller assembly coupled to an inner surface of the second side member. Each of the first roller assembly and the second roller assembly include a roller assembly frame and a plurality of wheels rotatably coupled to the roller assembly frame. The roller assembly frame supports the plurality of wheels at a slant that declines from a rear of the tugger frame to a front of the tugger frame. An actuator is configured to raise and lower the first roller assembly and the second roller assembly relative to the first side member and the second side member respectively.
