A subject of the present invention is to provide an overturning prevention apparatus for a forklift with various means. A cargo height H is calculated from a piston displacement detected by a displace sensor 21 and a cargo weight W is calculated by pressure P detected by a pressure sensor 22. A controller 20 detects a limit speed V1 in the case of non-cargo weight and a limit speed V2 in the case of the maximum cargo weight. By linearly interpolating the limit speeds V1 and V2, limit velocity Vc in the case that the cargo weight is W by utilizing a minimum turning radius memorized in the controller as a turning radius. If an actual velocity Va measured by a velocity sensor 23 is reached to the limit velocity Vc, the warning device 30 is actuated for warning an operator.

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.
