摘要： A diagnosis system for materials handling vehicles leads service personnel step-by-step through diagnosis and repair of faults within the vehicle. Faults are assigned corresponding event codes so that when a fault is detected, its corresponding event code is displayed. The event codes uniquely identify systems of the vehicle in which faults have occurred by having the event codes for a given vehicle system all start with the same number. Thus, the technician knows from the event code what system needs to be diagnosed/repaired and what tools and probable parts will be needed. The event code is used to access diagnosis information identifying the portion of the vehicle wherein the malfunction has occurred, the components which caused the malfunction and, preferably, provides a pictogram of that portion of the vehicle. The technician advances to the malfunctioning portion of the vehicle where another pictorial depiction of the components of that portion of the vehicle assists in locating the components. All components are marked within the vehicle by identifiers which are consistently used throughout the diagnostic information, pictorial representations and service manuals. The diagnostic information tells the technician what to do to diagnose the components with the diagnosis being preformed using the electronic control system of the vehicle to monitor inputs to and outputs from the electronic control system and to apply limited duration full power test signals to components to be tested. The diagnostic information is configured so that testing is done from the end of control paths back to the controller.

摘要： A pump motor control apparatus is adapted to control a pump motor of a forklift truck by using a driving transistor connected between a battery and the pump motor. The pump motor control apparatus includes a current detection circuit for detecting a current flowing through the pump motor to generate a current detection signal representing the current. A controller is employed to determine the load condition based on the current detection signal to thereby generate a control signal for use in the control of the driving transistor. The control signal is a pulse width modulation signal whose on-duty ratio is controlled depending on the load condition so as to decrease the torque and speed of the pump motor during the unloaded condition but to increase the torque and speed of the pump motor during the loaded condition.

摘要： In an electric lift truck, an asynchronous electric motor, a reversible sealed pump driven by the motor, communicating with the hydraulic actuators and also with a reservoir, a device which measures the angular position and the angular velocity of the motor, and a control and monitoring unit which causes the motor to be supplied according to the required speed of raising and lowering of the load support and on the basis of data supplied by the measuring device are used for raising and lowering the load support by means of one or more hydraulic actuators. There is a saving of energy in raising; there is also a recovery of energy in lowering, in which the motor acts as a generator to recharge the accumulator batteries of the lift truck.

摘要： A measuring system for testing the position of a vehicle (1) includes a number of optical beacons (6 and 7), a sensing device (10) which is mounted on the vehicle (1) and which generates a position signal when sensing light reflected from a beacon (65 or 7), and a computer processing unit (14) for calculating, starting from the information received from the sensing device (10), the deviation of the vehicle relative to the desired position and driving direction of the vehicle. The sensing device (10) includes two cameras which are mounted on the vehicle, namely, a first camera which is directed approximately along the driving direction, and a second camera which is directed along a direction vertically upward or downward relative to the plane including the path of travel of the vehicle. At least one of the beacons (6) is placed in such a way that, during the motion of the vehicle approximately along the desires path, the beacon can be seen by the sensing device (10) along the driving direction of the vehicle. At least another one of the beacons (7) is positioned along the desired path, but is observable in the direction above or below the aforementioned plane of the path, and is situated above or below the sensing device (10), depending whether the second camera is directed upwards or downwards relative to the plane of the path or travel, each camera may include its own light projector.
