Abstract: Tiller truck provided with force transmitter in order to transmit a pumping movement with the tiller to the wheels via a coupling in order to facilitate the movement of the truck. The coupling is arranged so that it can be set for force transfer forward or rearward or in an entirely free position. A control for the control of the coupling is arranged in the tiller handle.

Abstract: Tiller truck provided with force transferring means in order to transmit a pumping movement with the tiller (1) to the wheels via a coupling in order to facilitate the movement of the truck when this runs heavily due to a great load and/or uneven ground. The coupling is so arranged that it can be set for force transfer forward or rearward or in an entirely free position. A control (26) for the control of the coupling is arranged in the tiller handle.

Abstract: A steering handle of a pallet truck is arranged over a battery box on the truck. The steering handle is journaled so that it is in a turnable relation to an arm about a journaling point. The arm is journaled so that it is pivotable around a second pivot point. By pivoting the arm laterally a position may be achieved where the handle is easily accessible from the side of the truck. The steering handle is pivotably arranged in the outer end of the arm in a pivot bearing that in turn is pivotable in the arm and parallel controlled in relation to the truck. Between the steering handle and the journal for the pivot movement detection means are arranged to detect the mutual turning that is then used to electronically/electrically turn the steered wheel of the truck.

Abstract: A steering handle (1) of a truck is arranged over the battery box (2) of the truck. The steering handle (1) is journaled turnable in relation to an arm (3) around a journaling point (4), while the arm (3) in turn is journaled pivotable around a pivot point (5). By pivoting the arm laterally a position may be achieved where the handle is easily accessible from the side of the truck. The steering handle is pivotably arranged in the outer end of the arm in a pivot bearing that in turn is pivotable in the arm and parallel controlled in relation to the truck. Between the steering handle and the journal for the pivot movement detection means are arranged to detect the mutual turning that is then used to electronically/electrically turn the steered wheel of the truck.

Abstract: Method of braking a vehicle driven by an electric motors in particular a industrial truck, where the rotational speed of the motor is reduced according to a predetermined deceleration characteristic (a-d) when baking is activated. Preferably the deceleration characteristic is chosen in dependency of the length of depression of a brake pedal.

Abstract: Arrangement at tiller truck, at which the communication between the handle and the truck itself is done via a serial connection, for instance a serial cable (31) between a logic unit in the handle and a logic unit in the truck itself. A drive control (7, 8) includes a number of Hall-sensors (19) that are successively activated by a magnet (17) that is in turn mechanically activated, so that via a logic circuit a varied drive current is fed to the drive motor. The Hall-sensors (18) are arranged on a circuit card 19 that also include logic circuits. A safety control (belly button) (9) that is arranged on the handle. If the belly button is depressed this is on an inward protruding arm (21) provided with a magnet 22 that at this movement is moved so that it will influence one or several Hall elements belonging to the drive control (7, 8), at which however the magnet (22) is on the other side of a circuit card (20) that carries the Hall elements.

Abstract: In order to increase safety of lift trucks, a weight indication for the driver is provided so that the driver may know how heavy a load he is handling,. This weight indication is obtained by measuring the current to the motor of the hydraulic pump. In order to eliminate the risk that monetary variations may result in faulty measurements preferably a mean value of current is taken for a certain time or the value of the measured current is added during a fixed time interval. Obtained values are then multiplied by a conversion factor so that the weight in, for instance, kilograms is obtained and delivered to a suitable display device. Obtained values also may be used to provide a warning by sound or light should the load exceed the maximum allowed.

Abstract: A materials-handling fork-lift truck comprising a chassis (11) which is fitted with two forwardly extending, mutually parallel support legs (18), and a chassis-mounted lifting mast assembly (16) provided with a raisable and lowerable lifting fork (17). The lifting mast assembly can be moved along the support legs (18), between a first, mast-withdrawn position and a second, mast-extended position, in which the lifting fork is located close to the outer ends (19) of the support legs. The lifting mast assembly (18) is intended to be supported on the support legs (18), and a linkage mechanism (20) is provided for effecting movement of the mast assembly along the support legs. The linkage mechanism is also intended to constitute a horizontal support for the mast assembly (16).

Abstract: A handling apparatus for handling boxes stored in shelving compartments of storage shelving systems comprises a main body structure (11) which is adapted to be carried by a lifting device (12) and which is adjustable positionally thereby to a given level to be in registration with a respective shelf compartment (35). The body structure incorporates a plate-like support table (17) for supporting boxes (23), and a box dogging device (20) for dogging the boxes between the support table and respective shelf compartments. The box dogging device includes a vacuum device (21) which includes a plurality of suction cups (22) and which is movable along both the body structure and the support table. The dogging device and the support table are connected together so that the support table will move together with the dogging device during the initial and the final part of the movement of the dogging device.
