Abstract: When a determination result of a limitation determining section during a driving of a forklift is positive, a control section limits a vehicle speed and adjusts an engine speed. If a limitation canceling condition is met while the vehicle speed is limited, a control section cancels a vehicle speed limitation state, and executes a loading priority control in which an actuation of a loading device is prioritized. Thus, when a loading device is actuated during driving with a speed limit, the stability of the forklift is ensured while improving the workability of the loading operation.

Abstract: [Object] To provide a display method and a display device capable of performing an appropriate light emission control without providing an external sensor. [Solving Means] A panel drive current value K corresponding to a panel drive current In that is a sum of drive currents flowing into pixels 8R, 8G, and 8B is detected, and the panel drive current value K and a set current value Is that has been previously set are compared with each other. Then, when the panel drive current value K is equal to or higher than the set current value Is in a standard luminance display mode, the standard luminance display mode is switched to a high luminance display mode. On the other hand, when the panel drive current value K is lower than the set current value Is, the high luminance display mode is switched to the standard luminance display mode.

Abstract: A load determining section of a drive control apparatus for forklift determines a load state related to a loading attachment. In a case where a connection determining section determines switching to a connection state, if the load state determined by the load determining section requires that driving of a vehicle body be limited, a disconnection control section forcibly disconnects a transmission of a driving force to a drive wheel. Thus, the forklift is prevented from being started in a state that is likely to make the driving of the forklift unstable.

Abstract: A drive control apparatus for a forklift. Based on the load state, it is determined whether to limit a maximum vehicle speed and an acceleration/deceleration during traveling of the forklift.

A speed of the engine is adjusted based on the determined limitation contents, thereby controlling driving of the forklift. When the determined limitation contents are changed, an acceleration/deceleration limitation value is selected from a plurality of acceleration/deceleration limitation values according to the pattern of the change of the limitation contents, and drive control related to the acceleration/deceleration is executed to limit the acceleration/deceleration of the forklift by using the selected acceleration/deceleration limitation value.

Abstract: A traveling operation detecting portion detects traveling operation and non-traveling operation selectively. The traveling operation corresponds to operator operation that involves traveling of an industrial vehicle. The non-traveling operation corresponds to operator operation that does not involve the traveling of the industrial vehicle. An upper setting portion selectively sets a first engine speed upper limit and a second engine speed upper limit, which are different from each other, as an upper limit of an acceptable speed range of an engine in correspondence with a detection result of the traveling operation detecting portion. Thus, maximum advantage of the performance of the engine is ensured in correspondence with operation of the industrial vehicle.
