  • Patent number: 8875818
    Abstract: A tiller guided industrial truck having a steered wheel, a tiller arm, a travel speed controller, an actuating unit, a hold device, and a high speed travel switch. The tiller arm is pretensioned toward a vertical or near vertical position. The hold device limits a maximum travel speed to a walk along speed when activated and provides a snap-in position for the tiller arm in which the tiller arm is held. Further, the industrial truck has a circuit that initializes a braking process when the travel speed controller is not actuated while the high speed travel switch is activated.
    Type: Grant

  • Patent number: 8639421
    Abstract: Industrial truck with an electric travel drive and controls that can switch the electric travel drive to regenerative operation to brake the industrial truck, wherein an eddy current brake is provided that can be controlled or regulated by the controls during regenerative operation to brake the industrial truck, wherein the controls control or regulate the eddy current brake depending on the rpm of the electric travel drive, and wherein the controls control or regulate the eddy current brake in a manner such that the braking torque of the travel drive is supplemented at high rpms by the braking torque generated by the eddy current brake.

  • Publication number: 20120141193
    Abstract: The invention relates to a chain pin that is for connecting to a lifting chain of an industrial truck and having a longitudinal extension and can be guided in the longitudinal direction through a boring in a fork carrier and/or lifting frame of the industrial truck, and having on its first end a head with an extension perpendicular to the longitudinal extension that is greater than the inner diameter of the boring, where an elastic bearing element is arranged on the side of the head distant from the first end and surrounds the chain pin and has a first section and a second section, where the first section has an extension perpendicular to the longitudinal extension of the chain pin that is greater than the inner diameter of the boring, and the second section is formed so that it can be inserted into the boring.
