Upright receiver assemblies for attaching to trailers and acting as hitches are disclosed herein. The upright receiver assemblies include (a) an upright and (b) a base, both pieces being releasably attachable to each other. The upright contains a vertical post have a top positioned receiver while the base includes a center plate, two cross bars, and two angled side plates.

The primary purpose of this device is to reduce the fuel consumption of heavy trucks by improving airflow along the underside of a trailer, by way of a fairing mounted forward of the axles. This fairing is a teardrop shaped wedge with a flat bottom surface, which directs air towards the sides of the vehicle, while allowing a smaller volume to flow beneath the fairing such that it will clear the axles. Each axle is also covered by a flat panel, such that air will continue to travel smoothly beneath them. Attached to each panel is a brake cooling system, which consists of a pair of panels protruding downward, with their surfaces parallel to the direction of airflow. When the brakes are engaged, these panels rotate towards the center in an angled configuration, which redirects air towards the drums during and after braking, cooling them quickly and efficiently.

A trailer includes a load-bearing carrier frame which is guided on an undercarriage and includes a lateral longitudinal member and two cross members protruding at right angles from either end thereof. Between these, a central member is secured to the longitudinal member, parallel to the cross members, and a loading opening is formed opposite said longitudinal member. A lifting device is arranged, for mutual height adjustment purposes, between the carrier frame and the undercarriage. A load-clasping gripping unit may be arranged on the central member and may be displaced in the transverse direction between the longitudinal member and the loading opening.

A kingpin stabilizer having a kingpin-retaining bracket having a base plate and upwardly extending walls along at least two sides of the base plate. The upwardly extending walls and the base plate forming a receiving cavity with the upwardly extending walls spaced apart to fit said kingpin therebetween. At least one upwardly extending wall has a pin retainer. The stabilizer includes three telescoping legs extending from the pin-retaining bracket forming a tripod.

A simple and lightweight solution to the storage and delivery of dry flowable materials that is cost-effective, can be standardized to facilitate transportation and isolates the materials from exposure to air, insects and other contaminants. An apparatus includes a vessel and a delivery assembly, having a rotary feeder that upon gravity discharge of the dry flowable material moves such material to a desired location.

A transport safety system (400) for use in airports comprising a status monitor (300) for an airside dolly (200) used to improve airport safety. The status monitor (300) comprises a sensor (303) configured to sense a safety variable of the airside dolly and an output (301) in communication with the sensor (303). The output (303) is configured to provide a status signal in dependence on the sensed safety variable of the airside dolly (200).
