  • 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: 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.

  • 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.

  • Patent number: 9926178
    Abstract: An actuator includes a ram structure slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. A fluid passageway structure in the ram structure defines a path for fluid to flow through the ram structure and includes an outlet in a sidewall of the ram structure. A cushioning seal located between the ram structure and the cylinder structure can engage the ram structure and a cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward an open end of the cylinder structure. The cushioning seal can move during ram structure retraction in a direction of ram structure retraction such that fluid flowing out of the ram structure sidewall outlet, when the outlet is in the gap first portion, flows between the seal and the cylinder cap.

  • Patent number: 9783219
    Abstract: A tiller knob has a top section having a lower periphery with a first plurality of indented segments and a bottom section having an upper periphery with a second plurality of indented segments. When the lower periphery and the upper periphery are mated with one another, the first plurality of indented segments cooperates with the second plurality of indented segments to form separate openings around an outer circumference of the tiller knob. A center section is located between the top section and the bottom section so that outer surfaces of extending segments are exposed through the separate openings. A multi-sectional tiller knob having top and bottom sections formed of a first material and a center section formed of a second material is also disclosed.

  • Publication number: 20160052759
    Abstract: An actuator may comprise: cylinder structure, ram structure and a cushioning seal. The cylinder structure may comprise a cylinder tube, a cylinder base and a cylinder cap. The ram structure is slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. The ram structure may comprise fluid passageway structure for defining a path for fluid to move internally through the ram structure. The path may communicate with an outlet in a sidewall of the ram structure. The cushioning seal may be located between the ram structure and the cylinder structure and engage the ram structure and the cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward the cylinder structure outer open end.
