  • a contactor which is located in the vicinity of the consumer or by its control.
  • To control the contactors there is a connection to the controls or to an associated control, via which the contacts of the contactors are closed in the case of a corresponding command to supply the consumers with power.
  • the controls are often located on the tiller head.
  • an emergency shutdown with which the power supply can be quickly interrupted in a dangerous situation.
  • this can advantageously be designed in the form of a mechanically operable separation of the contacts of the contactors.
  • an actuating element such as e.g. arranged a percussion head. Pressing or hitting on this actuating element causes a separation of the contacts of the contactors via a mechanical connection.
  • a horn is usually provided, which is operated by a arranged on the tiller head control.
  • the horn can sound an audible warning.
  • the contactors are e.g. often combined with a control for the respective engine or arranged in the vicinity thereof.
  • the individual components must be individually housed in the development of the vehicle.
  • the object of the invention to provide a power supply for a truck available, which can be easily and inexpensively manufactured and installed regardless of the particular circumstances of the truck.
  • the main electromechanical components of the power supply are thus manufactured as a compact module with a single carrier.
  • the carrier summarizes the components to form a stable unit and can be advantageously designed as a mounting plate to which the components are screwed.
  • the power supply module is connected during installation with the housing of the drive part or with the mounting plate of another unit, such as the driving control.
  • the multipolar connector and the high current terminals are arranged on the carrier so that they are easily accessible for mounting the power supply module in the truck.
  • the pluggable fuse can conveniently be placed so that it can be easily replaced even with built-in power supply module.
  • the high current terminal for connection to a battery may be a simple screw connection, but preferably a special battery connector is used.
  • the power supply module When mounting a truck important advantages are achieved by the power supply module according to the invention. Thus, the individual components need not be distributed over the truck at different locations, e.g. on different boards or mounting plates of electronic controls.
  • the power supply module is pre-assembled and can be easily installed in a truck. It must be made only about a mounting of the module and a connection to the battery and the consumers on the intended high-current connections and with the control for the power supply module via the multi-pin connector. The simplified installation is less error-prone, time and cost consuming than the assembly of the corresponding components of a conventional power supply.
  • testing of the power supply module can be carried out before it is installed in the truck.
  • the standardized construction of the module also simplifies the connection to a corresponding test stand.
  • the power supply module can after the. Invention are used for different types of drawbar guided industrial trucks. Regardless of a specific truck type is intended to use a single carrier. This achieves economies of scale and the development of new vehicle types simplified.
  • the electrical design of the components for example, the switchable by the contactor maximum current can be adapted to the individual requirements of the truck.
  • the carrier forms a housing or is arranged in a separate housing.
  • the carrier can be designed as a trough-shaped or box-shaped plate and provided with a lid. This simplifies protection of the components from environmental influences, in particular against sprayed or condensed water.
  • the power supply module on an emergency stop operation.
  • the emergency stop operation consists of a arranged on the support mechanism for the separation of the contacts of the contactor, which is actuated from the outside.
  • on the carrier of the power supply module e.g. provided a displaceable slide, which is connected to a button, preferably a percussion head, directly or via a linkage.
  • the button protrudes from the body of the truck and acts on the emergency stop via a mechanical connection.
  • An arrangement of the emergency stop operation in the vicinity of the main contactor and a common installation of these components is particularly advantageous because the mechanical connection is simplified and thus in a particularly simple manner, a mechanical separation of the contacts of the contactor by the emergency stop operation is reached. A robust and reliable emergency shutdown is achieved.
  • the power supply module has an acoustic signal generator.
  • This can e.g. to be a horn or a buzzer.
  • An acoustic signal generator is usually required in every truck.
  • it can be integrated into the power supply module according to the invention. The effort for assembly is reduced compared to an elsewhere to be arranged separately acoustic signal generator.
  • the power supply module has a second contactor or a slot for receiving a second contactor for energizing a hydraulic pump motor or its control.
  • the motor for the hydraulic pump and that for the drive are controlled by a separate or a common electronic control. If two separate controllers are used, it is advantageous to use a second contactor for the second main consumer. It is then intended to integrate the second contactor in the power supply module.
  • the second contactor can be an integral part of the power supply module.
  • the power supply module is prepared by a corresponding slot for easy installation of the second contactor.
  • a separate high-current connection is provided for this purpose.
  • the high current connection is connected to the second contactor and provides a simple connection option for the hydraulic pump motor or its control.
  • the power supply module has a high-current connection for connecting a battery charger.
  • This possibility of connecting the battery to a battery charger via the power supply module is particularly useful in conjunction with a battery charger integrated in the truck.
  • the battery remains in the truck during charging so that it can remain connected to the power supply.
  • a fuse of the battery charger can be integrated into the power supply module.
  • the high current terminals of the power module are designed as high current fast connector terminals.
  • the high current fast connector terminals can be configured as clamp, screw or connector. It is thereby made possible further simplification in the assembly of the power supply module. Furthermore, it is provided to select the same type of high-current fast connector connections for all high-current connections.
