A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a steerable rear wheel assembly, a steerable front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

An electrical power system for a delivery vehicle is provided. The power system is used in connection with a delivery vehicle having an engine, and also having a liftgate powered by an electric motor. The electrical power system includes a first battery, a second battery, and an alternator. The electrical power system also includes a super capacitor. The super capacitor has a first capacitor bank and a second capacitor bank, wherein each of the first capacitor bank and the second capacitor bank comprises ultra-capacitor cells placed in series. The first capacitor bank and the second capacitor bank reside in parallel. In addition, the first battery and the second battery reside in parallel with the second capacitor bank. Together, the first battery, the second battery and the second capacitor bank supply power to the liftgate motor. Finally, the first capacitor bank is in electrical communication with the alternator and supplies power, with the alternator, to a relay start for the delivery vehicle to start the engine.

A hybrid power module is provided. The power module is associated with a truck having a lift gate. The power module includes a super capacitor comprising a bank of capacitors, with the super capacitor being in electrical communication with an alternator of the truck. The power module also includes a battery, a switch, a DC/DC boost converter, and electrical wiring. The electrical wiring connects the capacitor bank and first battery to the switch, and further connects the switch to a motor for the lift gate. The super capacitor and the first battery are positioned in parallel, with the super capacitor and the first battery residing proximate the lift gate. The super capacitor contains enough energy to power the electric motor for the lift gate through at least two operating cycles without the battery, protecting the lift gate if the battery goes weak.

The vehicle can have an engine and a moveable lift gate, a power unit driving the movement of the lift gate, the power unit including an electric motor and a capacitor pack, the capacitor pack being connected for powering the electrical motor, and being connectable to a DC alternator source of the engine.

A load-lifting device for mounting on a vehicle, including a platform for receiving a load which can be brought from a lowered into a raised working position, and back again, as well as a linking lever, a support element, a drive element and a connection element. The linking lever that is pivotally mounted on the platform is linked to the vehicle at a linking end region. The support element attached to the platform includes a foot end which braces the ground. The drive element brings the support element from a resting state associated with the resting position of the platform, into a working state in which the foot end is braced on the ground and the platform is raised into the working position. The connection element functions to control the rotational position of the linking lever and the pivot position of the platform according to the support element.

A wheelchair lift for a vehicle having a base for securing to a vehicle; a platform for accommodating a wheelchair; a lifting arm connected to the base and moveable between a raised position and a lowered position; a support arm connected between the lifting arm and the platform; a bridge plate connected to the platform and pivotable between a raised position and a lowered position; a platform folding linkage connected to the platform and arranged to contact the lifting arm during movement of the lifting arm between the raised position and the stowed position to raise the platform from a deployed position to a stowed position; a bridge plate control link connected between the bridge plate and the platform folding linkage; and a latch mounted on the bridge plate control link and arranged to latch the bridge plate in a raised condition.

An aircraft loader comprises a chassis, a cab, a loading floor and a load lifting apparatus. The load lifting apparatus includes a frame, a first horizontal platform and a second horizontal platform. The frame includes a pair of vertical columns. Each column has a front slider and a rear slider configured to be displaced vertically along the columns. The first platform is displaceable through movement of the rear sliders between a loading floor height and an aircraft loading height. The second platform is displaceable through movement of the front sliders and the first platform between an intermediate height and the aircraft loading height. When the first platform is raised from the loading floor height and reaches the intermediate height, the first and second platforms engage to so as to travel in unison, thus defining a loading deck which is displaceable between the intermediate height and the aircraft loading height.

Loading, shifting, and staging objects in automated or semi-automated fashion including systems, methods, and apparatuses for the same. The embodiments hereof enable automated and/or semi-automated loading, shifting, organizing, staging, and accessing of objects in different environments, e.g., those associated with a logistics network operation. For example, one such environment is a vehicle. In one aspect, a loading mechanism is used to load objects into a storage space of the vehicle. In another aspect, a shifting mechanism is used to shift objects in a storage space of the vehicle. In another aspect, a door assembly allows for automated opening and closing of a door into a storage space of a vehicle. In addition, methods of manufacturing and using the same are provided.

A transportation vessel includes a first sidewall and an opposing second sidewall. A load bar has a first end and a second end. The load bar is movable between a horizontal orientation and a vertical orientation. In the horizontal orientation, the first end is attached to the first sidewall and the second end is attached to the second sidewall, and the load bar may support cargo while the cargo is being transported in the transportation vessel. In the vertical orientation, the first end is attached to the first sidewall and the second end is unattached to the second sidewall.

A delivery robot control apparatus for controlling a delivery robot to unload an object and a method thereof are disclosed. A camera is provided in the delivery robot having an internal loading space for one or more floors and obtains an image including a door module which is provided in the delivery robot and connected to a frame forming the internal loading space. The controller determines up and low positions of the door module based on the image, and controls a first motor to move the door module to a target position based on the determined up or low position of the door module.
