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).

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.
