Abstract:
L'invention concerne un procédé d'assistance à la manœuvre manuelle d'un chariot d'atelier (1), équipé d'un dispositif d'entraînement (3a) d'au moins un organe de roulement (3) de ce chariot et d'une source d'énergie embarquée pour l'alimentation du dispositif d'entraînement (3a), caractérisé en ce qu'il consiste à permettre la commande du dispositif d'entraînement (3a) aussi longtemps qu'est constatée (8,9) la présence d'un effort exercé manuellement sur le chariot (1) d'une intensité supérieure ou égale à un seuil donné. L'invention concerne aussi un chariot pour mettre en œuvre ledit procédé.
Abstract:
L' invention concerne un chariot comportant un châssis de plateforme (1) auquel est fixée une roue motorisée (3, 3a) comportant un contrôleur (4) de son fonctionnement, commandé par au moins un interrupteur (6) situé sur un organe (5) de pilotage manuel du chariot, caractérisé en ce que le contrôleur (4) n'autorise un fonctionnement de la roue motorisée (3, 3a) qu'à partir de l'activation de l'interrupteur (6) et pour une durée déterminée par temporisation indépendante de l'état de l'interrupteur (6).
Abstract:
A motorised wheel or propulsion mechanisms grouping operating geometry that uses of various sensors to move in any desired direction. When a toggle direction is chosen, a controller determines the wheel to be restrained and/or to be moved in order to rotate the wheel in different directions to allow the movement of the mobility transport system in a specific direction. The power management (restrain and/or movement) is automatically synchronized between the wheels to ensure a proper path, either straight, curved and/or lateral and to provide the proper amount of traction under various surface conditions. Rolling resistance, wheel speed, and surfaces are other factors that may be controlled and added to the vector calculation in order to adjust the power to all motorised wheels so the desired direction of travel can be maintained.
Abstract:
A lift indicator assembly for a pallet truck includes a lift sensor assembly, and a lift status display for determining a lift condition of a load wheel of the pallet truck. The lift sensor assembly is to be carried by a fork of the pallet truck and includes a housing section, and a primary sensor assembly. The primary sensor assembly includes a first primary arm coupled to the housing section, and a first primary contact switch carried by the housing section and adjacent the first primary arm. The first primary contact switch has an engaged position and a disengaged position based on position of the first primary arm. The lift status display determines the lift condition of the load wheel based on position of the first primary contact switch.
Abstract:
A navigation system (30) for a vehicle, the vehicle including left and right motors (22, 24) for respectively causing rotation of left and right wheels and left and right motor drives(26, 28) for respectively driving the left and right motors, the navigation system including: an electronic gyroscope (36) mountable to the vehicle; and a control unit (32) configured to: receive an output signal from the gyroscope; derive a yaw angular velocity from the gyroscope output signal; derive a vehicle turning direction from the gyroscope output signal for non-zero yaw angular velocities; and cause the motor drives to apply a relative speed difference between the motors according to the yaw angular velocity and vehicle turning direction to thereby compensate for a change in vehicle heading.
Abstract:
The present invention is a motorized shopping cart retriever that includes a controller that attenuates the power provided to the drive system of the retriever to prevent the retriever from being utilized to move an excessively heavy load of shopping carts. By preventing the retriever and carts from being subjected to overloaded conditions, the operational lives of the retriever and carts are maximized. The retriever is also provided with a burst mode that allows the power provided to the drive system to rapidly increase past the normal attenuated level for a brief period of time in order to reduce the time required to accelerate a retriever loaded with carts to a terminal velocity.
Abstract:
A drive unit (12) comprising an electrical, stator-equipped drive motor (23, 24), a rechargeable source of energy (27, 28) connected to the drive motor (23, 24), wheels (17) driven by the motor in the drive unit, and a gearbox (25, 26) mounted between the motor (23, 24) and the wheels (17). The drive unit (12) is equipped with operating means (14, 41, 51, 61) arranged to operate the wheels forward and in reverse. The drive unit (12) is adapted to a serving cart (10) with an adapter (31) on the drive unit (12) to permit connection to the underside of the serving cart (10). The drive unit's (10) operating means are connected to the drive unit (12), either by wire or by wireless remote control from a location on the work-top (10) of the serving cart (10) and a serving cart with a similar drive unit.
