The vehicle-position-adjusting system is operated to detect a predetermined route so that the CPU device controls the vehicle-driving system to drive the forklift truck along the predetermined route from a first position to a second position. The pallet-scanning system is operated to scan a designated pallet along the predetermined route.

Disclosed is a container loading and unloading apparatus, which overcomes a problem of a conventional container in that a special equipment such as a forklift truck, a crane or the like is necessarily mobilized whenever the loading or unloading work is performed because the container is simply a cuboidal rigid body. The present invention makes it possible to perform the loading and unloading works of the container main body at the time of its storage and transportation without a separate loading and unloading equipment by providing a container supporter to secure a space for loading the container main body on a chassis of a freight car, thereby reducing equipments and labor as well as facilitating the loading and unloading works.

Automated inventory management and material (or container) handling removes the requirement to operate fully automatically or all-manual using conventional task dedicated vertical storage and retrieval (S&R) machines. Inventory requests Automated vehicles plan their own movements to execute missions over a container yard, warehouse aisles or roadways, sharing this space with manually driven trucks. Automated units drive to planned speed limits, manage their loads (stability control), stop, go, and merge at intersections according human driving rules, use on-board sensors to identify static and dynamic obstacles, and human traffic, and either avoid them or stop until potential collision risk is removed. They identify, localize, and either pick-up loads (pallets, container, etc.) or drop them at the correctly demined locations. Systems without full automation can also implement partially automated operations (for instance load pick-up and drop), and can assure inherently safe manually operated vehicles (i.e., trucks that do not allow collisions).

The invention discloses an unmanned transfer forklift based on laser positioning and stereoscopic vision and a navigation method. The unmanned transfer forklift comprises multiple reflection targets and tray targets arranged in a working scene of a forklift body; the forklift body comprises a control mechanism arranged at the front part, and a multi-gear pusher arranged at the back part; a laser radar and a binocular vision module scan the reflection targets to obtain distance signals of the forklift body and the reflection targets, and the distance signals are output to an industrial personalcomputer processing module; the industrial personal computer processing module controls the forklift body to advance and avoid from obstacles; the laser radar and the binocular vision module scan thetray targets to obtain distance and position information of the forklift body and goods on trays, and the distance and position information is output to the industrial personal computer processing module; and the industrial personal computer processing module controls the multi-gear pusher of the forklift body to operate. Through laser positioning and stereoscopic vision navigation, the navigation dead angle can be precisely detected, and the navigation accuracy is improved; and the obstacles can be accurately avoided, and the goods can be accurately forked, so that the transfer, taking and placement of the goods through unmanned driving are realized.

A pallet truck including a controller that calculates the height of the fork carriage without the use of mechanical devices such as switches or sensors. A calculated carriage height is derived by adding the amount of time that a carriage is commanded to be raised and offsetting that by the amount of time that the carriage lower button is depressed. The calculated carriage height is essentially an accumulated lift time where the time that the carriage is lifting is a positive value and the time that the carriage is lowering is a negative value. When these values are combined, the result is the present calculated carriage height. The controller further monitors the calculated carriage height such that if the carriage is too close to the ground, the maximum speed of the pallet truck is limited to prevent damage to the forks or ground due to striking or scraping between them.

A control system for a vehicle having a loader arm, such as a skid steer loader, telescopic handler, wheel loader, backhoe loader or forklift, reads a load height sensor, a load weight sensor; dynamically calculates the static center of gravity of the combined vehicle and load; calculates the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon; and limits the acceleration of the vehicle to less than the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon.

A twin sheet plastic pallet comprising an upper plastic sheet and a lower plastic sheet selectively fused to the upper sheet. The lower sheet has a generally rectangular configuration, including sidewalls and end walls, and includes a plurality of separate parallel upwardly opening longitudinally extending U-shaped grooves extending from end to end of the sheet and a plurality of downwardly opening U-shaped grooves interspersed between the upwardly opening grooves and opening in the end walls of the sheet. The upper sheet defines a top wall, defining the platform surface of the pallet, and a plurality of upwardly opening U-shaped protrusions extending downwardly from the top wall and sized to nest within the upwardly opening grooves of the lower sheet, whereby with the upper sheet positioned over the lower sheet and the protrusions positioned in the upwardly opening grooves, the sheets may be fused together to form double thickness U-shaped wall structures at the interfaces of the protrusions and the upwardly opening grooves. The pallet further includes a pair of longitudinally extending metallic beams positioned between the upper and lower sheets, and laterally aligned slots are formed in the U-shaped wall structures to allow passage of the forks of a forklift truck.
