Abstract: The present invention relates to a device for the safe interaction of unmanned loading machines and manned vehicles and persons, comprising: at least one spatial zone for the autonomous or teleoperated operation of an unmanned loading machine, wherein the zone is designed to adopt different states, wherein, in a first state of the zone, the autonomous or teleoperated operation of the unmanned loading machine is not allowed in the zone, in a second state of the zone, the unmanned or teleoperated operation of the unmanned loading machine is allowed in the zone, the device is designed to adopt the first state while or before a manned vehicle or a person enters the zone, and the device is designed to adopt the second state while or after a manned vehicle or a person leaves the zone.

Abstract: The invention relates to a system for controlling a work machine, in particular a wheel loader, having at least one hand-held control device (6), in particular a joystick or steering wheel, at least one restoring device (8) in the form of one or more spring assemblies, which are connected to the hand-held control device in such a way a restoring force is exerted upon the hand-held control device by the spring assembly when said spring assembly is not in the central position. An adjusting device (9, 12, 13) which engages with the spring assembly such that an adjustment of the central position of the spring assembly can be carried out, is provided.
