    Abstract: Example fan and light units and associated mounting arrangements for use at a loading dock are disclosed. An example apparatus includes a frame including a bar to be pivotally coupled to a support system via a point of attachment on the bar. The apparatus includes a fan and a controller to be coupled to the frame with the bar extending in a first direction away from the controller and toward the point of attachment, the controller to control operation of the fan. The apparatus includes a handle to be connected to a portion of the frame extending away from the controller in a second direction opposite the first direction, the handle spaced apart from a housing of the fan, the handle to be lower than the controller and lower than at least a midpoint of the fan when the apparatus is supported by the support system.

    Abstract: Example axial fans (overhead fans) include a set of radially extending spokes that connect a set of fan blades to a motor-driven hub. Each spoke has at least one notch, so the spokes can be assembled in interlocking relationship with each other, such that the spokes extend at different rotational angles from the rotational axis of the hub but lie in substantially the same horizontal plane. Such an arrangement enables the spokes to support the cantilevered weight and other vertical loads exerted by the fan blades while providing a compact assembly. In some examples, a retainer extends through aligned bores of several components of the fan along the axis of rotation.

    Abstract: Impact resistant retractable safety barriers are disclosed. An apparatus includes a support member, a flexible elongate member to extend and retract through an opening in the support member, and a stop member including a region to interface with the flexible elongate member. The stop member engages with structure of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening. The stop member cooperates with the structure of the support member to maintain a gap between a surface of the region of the stop member and the structure of the support member. A width of the gap is equal to or greater than a thickness of the flexible elongate member.
