Embodiments provide shelves, bracket systems, automated picker robots, totes, and other features that may be used with delivery vehicle configurations that have automated cargo areas. A delivery vehicle may include a picking robot that selectively retrieves packages for delivery without requiring substantial human intervention for locating those packages. The cargo area of the delivery vehicle may further comprise a plurality of customizable shelving units that generate custom-sized shelves for packages. The shelves may include a plurality of individually movable shelf brackets having retaining members that pivot between an extended and retracted position to hold the package in place and to enable the picking robot to retrieve the package from the shelf. Another embodiment provides for a tote having a drive mechanism to hold letters so that a letter may be automatically retrieved from the cargo arear and provided at a delivery location.

A drop deck trailer is provided with a deck that has the ability to raise and lower to conveniently load and unload goods and materials on the deck. A pneumatic system can raise and lower the deck and also serve as a suspension system for the trailer to dampen the relative movement between a frame and the deck. In addition, some embodiments of the trailer have a deck with a movable carriage that can move along the deck to automatically load a vehicle such as a golf cart. The carriage has rollers that secure the front wheels of a vehicle, and the carriage moves along the decks to pull the vehicle onto the deck. Moreover, various embodiments of a trailer frame can selectively connect to different decks to allow each deck to be specialized for particular goods and materials.

A liftgate alert apparatus for alerting drivers when a liftgate is down before driving includes a pressure switch configured to be coupled to an air line of an airbrake system of a truck or a trailer. The pressure switch is closed when the airbrake system is activated. A roller switch is in operational communication with the pressure switch and is configured to be coupled to a liftgate. The roller switch is closed when the liftgate is in a down position. An alarm is in operational communication with the pressure switch, the roller switch, and a power source. The alarm has an alarm ground wire. The alarm is configured to be coupled within a cab of the truck or on a front end of the trailer and activates an audio and or visual alert when both the pressure switch and the roller switch are closed.

A container transfer system is disclosed. The container transfer system can be installed on a vehicle or a rack. The container transfer system includes a conveyance assembly configured to move a container in a substantially horizontal direction along a longitudinal direction of the conveyance assembly. The conveyance assembly can include a frame comprising longitudinal members and transverse members and a plurality of rollers coupled to the frame. The plurality of rollers can include a first set of drivable rollers configured to be actively driven by a motor and a second set of passive rollers. The container transfer system also comprises a plurality of lift assemblies coupled between chassis rails of the vehicle and the frame of the conveyance assembly configured to raise and lower the conveyance assembly in a substantially vertical direction.

A method and an alignment system which auto-levels and/or auto-centers a loading platform to load and unload a wheeled stretcher to and from an emergency transport vehicle are disclosed. A controller of the alignment system receives a command to extend the loading platform from the emergency vehicle and extends the loading platform under power from the emergency transport vehicle. The controller recognizes an approaching wheeled stretcher, and aligns automatically the loading platform with a leading edge of the approaching wheeled stretcher to compensate automatically for any alignment issues between the loading platform and loading wheels of the wheeled stretcher.

Techniques are directed to utilizing a liftgate assembly having a platform, a lift subsystem constructed and arranged to selectively raise and lower the platform, and a set of steel beams coupled with the lift subsystem. The set of steel beams is constructed and arranged to hardware mount to a set of aluminum beams of a vehicle. Although the sets of beams are made of different materials, the liftgate assembly and the vehicle body may be securely fastened to each other making the vehicle well suited for a variety of conditions.

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.

A pipe coil lifting device includes a superstructure with a central longitudinal member and at least two supports attached to opposite sides of the central longitudinal member, with two channels at the outside long-edges of the superstructure attached to the supports, with a convex upper surface attached to the supports of the superstructure.

A pivoting system has an electronic device pivotably mounted on a cargo platform. A base is coupled to a cargo support. A linkage rod slidably engages with the cargo platform. A proximal pivot pivotably couples the proximal end of the linkage rod arm to the base. A device pivot pivotably couples the electronic device to the cargo platform. A distal pivot pivotably couples the distal end of the linkage rod to the electronic device. The pivoting system causes pivoting of the electronic device between a lower general horizontal position and an upper general horizontal position.

A vehicle has at least two axles, each having at least one wheel for lifting, transporting, and lowering load carriers. A first axle is mounted in a chassis. Lifting elements are provided for lifting and lowering the load carriers. The distance of the second axle relative to the first axle can be changed in the horizontal longitudinal vehicle direction, and the lifting elements are lifted or lowered by a change in the distance of the second axle from the first axle. The at least one wheel of the first axle can be driven by a drive motor that is arranged on the chassis, and at least one lifting element is displaced horizontally inward or outward by the change in the distance of the second axle from the first axle in the transverse vehicle direction.
