Robotic vehicle and use thereof for displacing a holder for goods, which is for instance loaded with goods, which vehicle can be operated in an empty position and a loaded position, comprising of (1) moving the robotic vehicle to a position under the holder in a first direction, wherein the robotic vehicle is in the empty position, wherein a holding means is countersunk in a body of the vehicle; (2) lifting the holder, wherein the robotic vehicle lifts the holder by performing a vertical movement of the holding means relative to the wheels of the vehicle, such that the holding means comes into contact with an underside of the holder, wherein the robotic vehicle transfers to the loaded position; (3) rotating driven wheels of the robotic vehicle from the first direction to the second direction without the body of the vehicle being rotated, and (4) displacing the robotic vehicle in the loaded position in a second direction, wherein the first and second direction enclose a mutual angle of between 60 and 120 degrees, preferably 75 and 105 degrees, more preferably 85 and 95 degrees, such as a substantially right angle.

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 rear wheel assembly, a 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.

Described herein are systems and methods for using different truck types for deliveries. A package is initially loaded into a specially configured cargo container that can be transported either on a primary truck or a secondary truck. A secondary truck is smaller than a primary truck and is configured to transport fewer cargo containers than the primary truck. An initial leg of the overall delivery (e.g., from a warehouse to a transfer point) is performed using a primary truck. The cargo container is then transferred to a secondary truck, which completes the delivery. Empty cargo containers can be transferred back to a primary truck, e.g., in a stacked or folded manner, for transporting back to the warehouse. The configurations of primary and secondary trucks are such that these transfers can occur at any location (e.g., a parking lot) with minimal human involvement.

A luggage board apparatus for a vehicle includes an upper board and a lower board. The upper board and the lower board are capable of moving together in a vertical direction, and the upper board is capable of moving in a front-rear direction with respect to the lower board. A shopping cart may be seated, loaded and stored on the luggage board by using a slide rail provided on the luggage board and a slide roller coupled to the slide rail on the luggage board.

A car hauler with battery powered electric actuators as the sole mechanism for positioning the vehicle decks. The electric actuator system completely replaces and eliminates the need for the traditional car hauler hydraulic system requiring pumps, valves, hydraulic hoses, hydraulic cylinders, hydraulic fluid reservoir, and hydraulic fluid to position the vehicle decks. The electric actuators are self-locking and do not need to be pinned like traditional hydraulic actuators. The overall weight of the electric actuator system is much less than the hydraulic actuator system and permits complete loading and unloading of the car hauler without running the diesel tractor engine.

A system includes a trailer frame, a lifting mechanism coupled to the trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe, a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, and a hydraulic power unit configured to hydraulically power the system.

An onboard platform for loading cargo into and unloading cargo from a trailer includes a first portion comprising a plurality of beams secured together. The first portion is configured to provide stability and rigidity to the platform. The onboard platform also includes a second portion comprising a turntable rotatably attached to the first portion proximate a center point of the turntable, the turntable configured to move about the rotational attachment in a selected range of degrees relative to the first portion. The onboard platform is configured to move between in a first position where the platform is stowed below a bed of the trailer and a second position where the platform extends from an edge of the bed of the trailer and is secured into the second position to aid in loading cargo into and unloading cargo from the trailer.

A trailer for towing a power vehicle is provided and generally includes a frame and a self propelled tandem wheel assembly. The frame includes an undercarriage chassis, and the self propelled tandem wheel assembly is positioned under the undercarriage chassis. The self propelled tandem wheel assembly includes a rear wheel assembly and a front wheel assembly, and the rear wheel assembly and the front wheel assembly are equally positioned to support the undercarriage chassis.
