When an engine is operated, a power dividing mechanism divides power of the engine to output the power to a motor for running operation and a motor for a cargo handling operation, respectively. Each of loads is driven via a rotational shaft of a corresponding one of the motors. By operating the engine and supplying the motors with electric power from a battery to operate the motors, each of the loads can also be driven by the sum of power of the engine and power of a corresponding one of the motors. When surplus power is generated in the power of the engine, each of the motors is operated as an electric power generating unit by the surplus power. As a result, the battery is charged.

A camera lifting apparatus is used in an industrial vehicle equipped with a cargo handling apparatus for lifting a cargo carrying carriage up and down along a mast provided on a vehicle body. The carriage has a cargo carrying apparatus. The camera lifting apparatus comprises a camera unit attached to the cargo carrying apparatus. The camera unit has a camera for picking up an image of a work area of the cargo carrying apparatus. A moving mechanism moves the camera unit relatively to the cargo carrying apparatus. An actuator drives the moving mechanism.

A two-way clutch is provided between an engine and a generator motor. Further, a battery and a cargo handling pump are provided. The generator motor is set to either a generator mode or an electric motor mode. When a cargo handling load (detected by a sensor) is small, the two-way clutch is set to a first state in which transmission of driving force from the engine to the generator motor is allowed and in which transmission of driving force in reverse is prevented. Further, when the engine is stopped or idled, the cargo handling pump is driven by the generator motor in the electric motor mode. When, during the above operation, the load increases to a level above a predetermined value, an increase in output of the generator motor and an increase in engine RPM are started, and when the engine RPM becomes equal to the RPM of the generator motor, which previously increased, the two-way clutch in the first state is connected, and the cargo handling pump is driven by the engine.

Operating apparatus for a working industrial vehicle

A load handling operation control apparatus for an industrial vehicle, which has a load carrying apparatus provided movably on a vehicle body, is provided. A load carrying apparatusis positioned with a load handling targetaccording to its movement. A load handling control sectionhas a display deviceand a detection device for detecting the position of the load handling target. A image control sectiondisplays positioning information for supporting positioning of the load carrying apparatuswith respect to the load handling targeton the display devicebased on a positional detection result detected by the detection device.

A steering wheel mounted on a forkliftis provided with a steering wheel knobwhich can be operated with one hand holding it. The steering wheel knobhas an approximately egg-like shape with switchesprovided on its end face. Incorporated in the steering wheel knobare a transmission circuit, which radio-transmits a signal when the switchesare operated, and a battery. The signal transmitted from the steering wheel knobis received by a reception sectionon a vehicle bodyand a controllerexecutes predetermined control based on that signal.

A camerapicks up an image of a cargo handling target and acquires image data of a mark affixed to the cargo handling target. An image processing sectionperforms image recognition of the mark and acquires the position and size of the mark in a screen coordinate system. A real coordinate position calculating sectionacquires the position of the camerain a real coordinate system based on the obtained position and size of the mark. Based on the position of the cameraa deviation amount calculating sectionacquires a deviation amount between the current position of forks and a target position. A cargo handling control sectionexecutes automatic positioning control of the forks in such a way that the deviation amount becomes zero.
