Abstract: A light signal device for a driverless transport system, includes a front element having a plurality of optically transparent light exit openings and at least one light generating unit having a light guide and having two light sources arranged at opposite ends of the light guide. The light guide has a plurality of light decoupling elements in order to emit light through the light exit openings. Light exit openings are arranged on the front element in a plurality of rows and a separate light generating unit is provided for each of the rows. A light signal arrangement for a driverless transport system includes a plurality of such light signal devices. A driverless transport system includes the light signal device and a controller. Use of the light signal device is for visualizing an operating state of a driverless transport system. An operating method for the light signal device is also disclosed.

Abstract: Disclosed is an operator platform designed as an exchangeable assembly unit, for mobile construction machinery, having a carriage for translational adjustment and a rotatable seat mounting for rotary adjustment of a seat, which also relates to a driver's cab with an operator platform of this kind.

Abstract: A manual control device includes an actuation member which is supported on a switching rod for pivoting about at least one actuation member pivot axis which extends perpendicularly to the longitudinal axis of the switching rod. Furthermore, the switching rod is movably supported relative to a base member of the manual control device about or along a plurality of switching rod movement axes, there being provided restoring means, by means of which the actuation member which has been redirected out of a rest position about the actuation member pivot axis can be restored to the rest position. The restoring means have at least two resilient elements which are active counter to redirection of the actuation member from the rest position about the actuation member pivot axis and which are arranged radially opposite each other relative to the longitudinal axis of the switching rod.

Abstract: The invention relates to a push-button (5) having a housing (10), with which there are associated at least a first actuation member (6) which triggers a haptic control signal and one or more permanent magnet(s) (3) which can be guided past at least a second actuation member (2) which triggers a switching operation, and there is associated with the first actuation member (6), which triggers a haptic response, a control element having a first progressive or degressive control face portion (6.1) and at least a second adjoining control face portion (6.2) which behaves in an inverse manner and along which the actuation member is guided.
