  • Publication number: 20240083272
    Abstract: A materials handling vehicle including a vehicle-side charging contact assembly coupled to a battery, a steerable drive wheel defining a drive wheel track width W, and a pair of load wheels defining a load wheel gap G between the pair of load wheels that is larger than the drive wheel track width W. A charging station includes a pair of floor-side charging contacts configured to transfer charging current to the vehicle-side charging contact assembly. The pair of floor-side charging contacts define an inner contact spacing S1 that is larger than the drive wheel track width W, and an outer contact spacing S2 that is larger than the inner contact spacing S1 and smaller than the load wheel gap G to permit passage of the steerable drive wheel between the floor-side charging contacts, followed by passage of the pair of load wheels outside of the floor-side charging contacts.

  • Publication number: 20230086678
    Abstract: A materials handling vehicle comprising a hitch system, and a drive mechanism. The hitch system comprises a hitch and a hitch controller. The hitch comprises a latch, one or more sensors, an actuator, and a receiving member. The latch is positionable between open and closed positions. The actuator is positionable between retracted, intermediate, and extended positions. The receiving member is configured to lead a cart hook to engage the latch when in the closed position. The one or more sensors are configured to detect a position of the latch and a presence of the cart hook received within the receiving member. The hitch controller is configured to position the actuator in one of the retracted position, the intermediate position, and the extended position, and to position the latch in one of the open position and the closed position in response to signals received from the one or more sensors.

  • Publication number: 20230092293
    Abstract: A materials handling vehicle comprising a hitch, and a drive mechanism. The hitch comprises a latch and a receiving member. The latch is positionable between open and closed positions. The receiving member comprises a pair of inwardly curved side scoops and a central incline member provided between the pair of inwardly curved side scoops, each inwardly curved side scoop having an upper surface, a lower surface opposite the upper surface, an inner surface, an outer surface opposite the inner surface, a rear surface, and a front surface opposite the rear surface. The rear and upper surfaces of the pair of inwardly curved side scoops define an open rear end of the receiving member, the upper surface being sloped at the open rear end. The central incline member and the upper surface of the pair of inwardly curved side scoops cooperate to lead a cart hook to engage the latch.
