摘要： A travel control apparatus for a forklift is disclosed. The forklift is provided with a loading device that performs load handling operations by raising and lowering a load, and a drive motor which generates a drive force for travel and is capable of generating a braking force. The apparatus is provided with a sensor for detecting the speed of the motor, a seat switch, a height switch, a load sensor, and a control section. The control section causes the drive motor to generate a braking force when the seat switch detects that the driver has left the seat in the case where the motor speed sensor detects a traveling state, and also changes the strength of the braking in accordance with the height of the loading device and the weight of the load.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
