Abstract: A warehouse truck includes an electric truck contact in direct connection to or on a battery. The electric truck contact is arranged to take part in the switching between three battery modes. The truck contact includes a first group of guides that cooperate with a second group of guides on a truck charging contact and a third group of guides on a truck operation clamp.

Abstract: The invention relates to an industrial truck (10; 15) comprising a truck body (20) and a load supporting member (30). The load supporting member (30) is movable in a vertical direction (40) and in a horizontal direction (50; 80) in relation to the truck body (20). According to the invention, the industrial truck (10; 15) is adapted to reduce the maximum allowed acceleration of the load supporting member (30) in the vertical direction (40) when the load supporting member is located at specific horizontal positions in relation to the truck body (20). The invention also pertains to a corresponding method and a computer program.

Abstract: Method for cleaning hydraulic liquid in a industrial truck, wherein said industrial truck is an electrically powered industrial truck having a battery as an energy source with a hydraulic system comprising, a hydraulic pump, a hydraulic reservoir, and a return pipe to the hydraulic reservoir with a return filter, wherein the method comprises the steps of, the hydraulic pump is activated for hydraulic activity, the hydraulic pump pumps the liquid for the hydraulic activity and in relation to this return flow through the return filter to the hydraulic reservoir occurs, the hydraulic pump can be activated by means comprised in the industrial truck, when hydraulic activity is not present, by that achieving a circulation to the hydraulic reservoir through the return filter such that sufficient filtration of the hydraulic liquid is reached, further a time Tb for circulation without hydraulic activity can be accumulated and/or a sensor for determining the quality of the hydraulic oil can be arranged in the industria

Abstract: The invention relates to an industrial truck comprising a first mast comprising two uprights and a first and a second load carriage arranged to be independently moved in the vertical direction wherein a second mast is arranged between the uprights of the first mast and that the first load carriage is arranged to be moved along the first mast and the second load carriage is arranged to be moved along the second mast.

Abstract: An assisted power steering system and a method for assisting a turning of a steered wheel of a steering system comprising an energy source arranged to assist the turning of the steered wheel, a sensor arrangement arranged to detect direction of the turning, and a control unit arranged to control the energy source based on data from the sensor arrangement, wherein the sensor arrangement comprises at least one first digital sensor arranged to indicate the direction of the turning.

Abstract: An industrial fork lift truck comprising an electric motor (3), a motor controller (2) for controlling the electric motor (3) and a truck computer (1) for controlling the motor controller (2), said truck computer (1) comprising a detection system (5) for detecting spinning and/or locking of the drive wheel of the truck characterized in that the detection system (5) is arranged to receive a signal corresponding to the momentary torque current of the motor (3); and further comprising: a calculation unit (12) for calculating the theoretical torque current of the motor (3); a comparison unit (13) for comparing the theoretical torque current of the motor (3) and the momentary torque current of the motor (3), wherein the truck computer is arranged to reduce the acceleration or the deceleration of the truck if there is a difference between the theoretical torque current of the motor (3) and the momentary torque current of the motor (3).
