摘要： A barrier system includes a handrail, and a connector to couple the handrail to a post extension that extends upward from a floor. The handrail has and end with a width measured in a direction transverse to an elongate length of the handrail. The connector includes a socket to hold the end of the handrail. The socket is defined by an elongate channel that extends in a direction substantially parallel to the post extension when the connector is attached to the post extension. The channel has a length that is greater than the width of the end of the handrail.

摘要： 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.

摘要： Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: an elongate upper ledge, a post coupled to the upper ledge, an extendible leg telescopically coupled to the post, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer based on movement of the extendible leg relative to the post, and a plurality of wheels coupled to the post, the post to maintain the plurality of wheels at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved, each of the plurality of wheels to be equidistant from a vertical axis traversing through a center of the upper ledge.

摘要： 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.

摘要： 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.

摘要： Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first sensor to face a first direction to detect oncoming traffic in a first area, a second sensor to face a second direction to detect oncoming traffic in a second area, and a first display to face the first area. The first display is to display a first signal in response to (1) the first sensor not detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first display is to display a second signal in response to (1) the first sensor detecting the oncoming traffic in the first area and (2) the second sensor detecting the oncoming traffic in the second area. The first signal is different than the second signal.

摘要： Example portable trailer stands for supporting parked trailers are disclosed herein. Some example portable trailer stands disclosed herein comprise two telescopic posts supporting a generally horizontal beam. Some examples include spring-loaded retractable wheels for selectively installing and removing the trailer stand from underneath a trailer left parked on a driveway. After being positioned under the trailer, the posts extend to lift the beam solidly up against the underside of the trailer. To accommodate conditions where the driveway is not parallel to the trailer's underside, some example posts can be lengthened independently and have angular play that allows the beam to tilt. In some examples, the horizontal axle of the trailer stand wheels is perpendicular to the beam so that the trailer stand can be readily installed from either the front or side of the trailer. Some examples have a kingpin-receiving groove in the beam or have some other kingpin-receiving feature.
