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: In an industrial vehicle, a controller controls an energizing state of an electromagnetic control valve. The controller is electrically connected to a driver detection switch and a position detection switch. The controller breaks energization of the electromagnetic control valve if the driver detection switch detects that a driver of the vehicle is not seated. The controller energizes or reenergizes the electromagnetic control valve if the driver detection switch detects that the driver is seated and the position detection switch detects that the manipulation position of the direction indication member is a neutral position and then a forward or backward position.

Abstract: A display device includes the following elements. A display has a display area and includes an electro-optic layer and a light-reflecting layer reflecting light emitted from the electro-optic layer to the viewing side of the display device, the light-reflecting layer being arranged in the display area. A plate-shaped exterior has a frame area including a portion located outside the periphery of the display. An antireflective plate continuously covers both of the display area and the frame area. The antireflective plate prevents external light, which enters the viewing side of the display device and is reflected by the light-reflecting layer or the frame area, from emerging on the viewing side.

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.
