  • Method of installing a quick change load wheel assembly
    Patent number: 8881366
    Abstract: A load wheel assembly for a materials handling vehicle includes first and second spaced side members, at least one rotatable roller extending between the first and second side members. An interface structure provides a substantially rigid connection between the load wheel assembly and a mounting structure on the materials handling vehicle. The mounting structure includes a transverse bar and the interface structure includes a portion that engages and mates with the transverse bar to form a rigid connection between the interface structure and the transverse bar.
    Type: Grant

  • Fan blade with ridges
    Patent number: 7494325
    Abstract: A blade including a body having a leading edge, a trailing edge, a surface point of maximum camber, and a low pressure surface extending between the leading edge and the trailing edge. The body further includes a high pressure surface extending between the leading edge and the trailing edge on an opposite side of the body relative to the low pressure surface. The low pressure surface includes a leading edge surface extending from the leading edge to the surface point of maximum camber. The blade further includes at least two ridges located on the leading edge surface, each ridge extending generally parallel to the leading edge.
