A cargo vehicle is disclosed having a composite floor assembly with at least one embedded hardpoint connector. The composite floor assembly may comprise a plurality of transverse beams, wherein a subset of the plurality of transverse beams includes at least one embedded hardpoint connector. The embedded connector may be used to securely and removably couple other vehicle components to the composite floor assembly, such as a landing gear assembly and/or a slide rail assembly.

A floor securing apparatus comprises a riser slot formed in a floor riser transverse to a longitudinal axis of the floor riser, the floor riser configured to support a floor sheet and a key including a locking head and at least one anchor tab, wherein the key is slidable into the riser slot transverse to the longitudinal axis of the floor riser, wherein the key is configured to engage a portion of the floor sheet to prevent vertical movement of the floor sheet relative to the floor riser.

A semi-trailer has a rear impact guard including an elongated horizontal member that attaches to a trailer by a pair of vertical guards. The horizontal member may have a top surface, a bottom surface, and a leading edge from which a surface of the guard member extends rearward to the top or bottom surface. The rear impact guard may include a pair of gussets that extend from the vertical guards. Each gusset may include a main generally planar portion, a first stiffening flange perpendicular to the main portion, and a second stiffening flange perpendicular to the first stiffening flange.

A transportation refrigeration unit TRU (26) and power system. The TRU (26) and power system including a compressor (58) operatively coupled to an evaporator heat exchanger (76) and an evaporator fan (98) configured to flow a return airflow (134) over the evaporator (76). The system also includes a return air temperature RAT sensor (142) disposed in the return airflow (134) and configured measure the temperature thereof, a TRU controller (82) connected to the RAT sensor (142) that executes a process to determine an AC power requirement for the TRU (26) based on the RAT sensor (142); a generator power converter (164) configured to receive three phase AC power (163) from a three phase AC generator (162) and transmit a second DC power (165b) to an energy storage system (150); a power management system (124a) configured to receive three phase AC power (157) from at least the energy storage system (150) and generate a TRU DC power (129), and directing the TRU DC power (129) to the TRU system (26).

A method of manufacturing a transport refrigeration unit is provided. The method includes providing an enclosure including an outer layer and a supporter. Providing the enclosure includes supplying one of a first material and a second material to a mold. This also includes supplying the other of the first material and the second material on the one of the first material and the second material that is supplied to the mold. Also, this includes curing the first material and the second material integrally that are supplied to the mold. The first material forms into the outer layer and the second material forms into the supporter. The second material includes a plurality of reinforcing fibers.

An apparatus for attachment to a panel configured for partitioning a trailer cargo space includes a member having a cross-section with a concave receiver section including a laterally extending support section connected to sidewalls extending perpendicular to the support section, the receiver section dimensioned for attaching the member along a panel edge with sidewalls engaged against opposite sides of the panel and the support section contacting the panel edge, and first engagement feature(s) disposed opposite and extending along an edge surface of the panel assembly, and a first stacking plate including a first side having feature(s) complementary to the first engagement feature(s), such that the member and the first stacking plate engagingly mate, and an opposite side with second engagement feature(s) similar to the first engagement feature(s), such that the first stacking plate engagingly mates with a second stacking plate.

A refrigerated composite semi-trailer is disclosed that may improve thermal efficiency, fuel efficiency, and costs of manufacturing.

An electric truck has a chassis, on which a driver's cab with a motor compartment containing an electric motor is disposed in the front of the electric truck, and in the rear a cargo body rests on the chassis. The cargo body substructure sits on vehicle longitudinal beams of the chassis. The cargo body bottom sealing the cargo body on the underside is spaced above the vehicle longitudinal beams to ensure clearance for a sufficient spring travel. A battery housing with at least one integrated battery is disposed in the intermediate space between the vehicle longitudinal beams and the body bottom, so that a larger installation space is available for the batteries and therefore a greater range for the electric truck. The battery is protected in this region and, moreover, the insulation of the battery housing simultaneously contributes to insulation of the cargo body disposed above the battery housing.

A thermal radiation shield for the floors and roofs of trailer reefer units. The shield includes a low-emissivity, heat reflecting film that includes a metal coating layer, preferably vapor deposited, further protected by a layer of durable PET film.

An automatic coupling system for connecting grid power to charge the battery of a battery powered electric semi-trailer reefer and a method for automatically, directly providing electrical power to a battery powered electric semi-trailer reefer battery. The method comprises providing an auxiliary power source and electrically connecting said auxiliary power source to a parking surface charging pad for each leg of a landing gear for a battery powered electric semi-trailer reefer. The parking surface charging pad contains an electrode plate in it. Also provided is a landing gear electrical contact pad containing an electrode on a lower end of each leg of the landing gear.
