  • Lifting device of an industrial truck and method for setting down a load carried on load handling means of an industrial truck on a surface
    Patent number: 10343883
    Abstract: A lifting device of an industrial truck includes a load handling arrangement that is raised and lowered on a lifting frame and a hydraulic lift cylinder device that is actuated by an electrically actuatable control valve device, in which an electronic control device is provided to actuate the control valve device. The electronic control device has an automated set-down mode actuated during a lowering of the load handling arrangement. The load is lowered at a lowering speed specified by a deflection of a control element to the designated surface. As the control element continues to be deflected into the lowering position, the lowering of the load handling arrangement is terminated by the electronic control device by actuating the control valve device into a shut-off position to prevent the load handling arrangement from being set down on the designated surface.
