Abstract: An autonomously guided industrial truck comprising a vehicle body and a pair of support arms extending from the vehicle body. The vehicle body defines a longitudinal direction and a width direction of the industrial truck in sections in plan view of the industrial truck. Each of the support arms extending from the vehicle body has at least one load wheel. The industrial truck includes a pair of support wheels or drive wheels located underneath the vehicle body on a driving surface and opposite one another relative to the width direction. The industrial truck includes a pair of scanner units arranged vertically above the support wheels or drive wheels. The pair of scanning units defines a scanning plane with respective scanning regions each scanning unit of the pair of scanning units, and wherein the respective scanning units are symmetrically opposite one another within an outline of the vehicle body in the width direction of the industrial truck.

Abstract: An industrial truck includes a vehicle frame and a drive unit. The drive unit includes a drive wheel movably mounted to the vehicle frame and a spring unit. The spring unit includes a hydraulic cylinder positioned between the vehicle frame and the drive unit and a switchable valve configured to define a blocked state. The spring unit is configured to pretension the drive wheel against a ground surface. When the switchable valve is in the blocked state, a one-sided movement of the hydraulic cylinder is blocked.

Abstract: An industrial truck comprises a load part comprises a load-carrying means including at least one load wheel and a drive part including a vehicle frame defining an opening. A steerable drive wheel and at least one support wheel are arranged on the vehicle frame. The at least one support wheel is arranged on a side of the drive wheel that faces away from the load part and is mounted as a trailing wheel that swivels about a vertical axis. The at least one support wheel is configured to at least partially protrude through the opening defined in the vehicle frame.

Abstract: An industrial truck includes a drive part with a drive frame and a load part. The load part includes a lift frame having a load frame, which includes a plate, a load-carrying means connected to the plate, and at least one bearing head configured to receive a lift cylinder. The at least one bearing head is connected to the plate.

Abstract: The invention relates to a method for marking wafers, in particular wafers for solar cell production: The method comprises the steps of manufacturing a position line (21a, 21b, 21c) on a peripheral surface of a silicon ingot or column, the ingot or column extending in an axial direction and having a longitudinal axis in the axial direction, wherein the position line extends in the axial direction along substantially the whole ingot or column and is inclined with respect to the longitudinal axis. By this position line it is possible to determine the position of a wafer cut from the ingot or column within the ingot or column, respectively. Further, an individual identification pattern (20a, 20b, 20c) of lines on the peripheral surface of the silicon ingot or column is manufactured, the individual identification pattern of lines extending in axial direction over substantially the whole ingot or column and providing an individual coding which allows to identify the silicon ingot or column.

Abstract: A preassembly unit for the drive of an industrial truck, with a fifth wheel on which the driving wheel is rotatably mounted around a horizontal axis and which on its part is rotatably mounted in a bearing member around a vertical axis, a drive motor arranged on the fifth wheel, which is coupled with a driving shaft of the driving wheel via a gearbox, optionally a steering motor on the bearing member in order to turn the fifth wheel in the bearing member around the vertical axis, a parallel rod assembly between the bearing member and a frame of the industrial truck, which permits an essentially vertical movement of the preassembly unit in relation to the frame, and a spring arrangement between the bearing member and a frame-fixed section, wherein at least one upper drag rod of the parallel rod assembly is articulated on the lower end of a separate attachment section, which forms an interface with a counter-attachment position on the frame by attachment positions, and that at least one spring acts between a sho
