A switchback control apparatus for an industrial vehicle, includes a forward and reverse operating part, a forward and reverse position detector detecting a position of the forward and reverse operating part, a vehicle speed detector; and a shift control section shifting the transmission forcibly to a first speed stage and then, releasing the first speed stage of the transmission that is set forcibly when the forward and reverse operating part is shifted from the forward position to the reverse position or from the reverse position to the forward position by the forward and reverse position detector and a vehicle speed detected by the vehicle speed detector greater is than or equal to a threshold value that is smaller than a shift-up vehicle speed for shifting the transmission from the first speed stage to a second speed stage.

Switchback control apparatus for industrial vehicle

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. Limitation contents regarding the maximum vehicle speed and the acceleration/deceleration is determined based on a determination result of whether to put the limitations. 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.

Drive control apparatus for forklift

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.
