  • 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.

  • Patent number: 8757326
    Abstract: A lift truck includes a frame defining a main structural component of the lift truck, a mast assembly secured to the frame, first and second lower forks, first and second upper forks, and first and second pallet stops. The lower forks are secured to the frame and are provided for supporting a lower load carried by the lift truck. The upper forks are located above the lower forks and are provided for supporting an upper load carried by the lift truck. The upper forks are movable with respect to the lower forks along the mast assembly. The pallet stops position the lower load on the lower forks and are secured in place between the mast assembly and the frame at laterally spaced apart locations. Each pallet stops includes a surface for contacting the lower load and for maintaining the lower load at a desired axial position.
