Abstract
A control system includes an intuitively working remote control operating unit which has a first pair of control elements for controlling a movement of a hoist, in particular a trolley of a crane, in two opposite movement directions along an axis. One control element is assigned separately to one movement direction and the other control element assigned separately to the other opposite movement direction. The control elements are so disposed as to form a side-correct representation of the movement directions, wherein assignment of the control elements to the movement directions corresponds to an orientation of the operating unit in relation to a directed external field and is swapped, when the operating unit is oriented in opposite direction.

A control system, comprising an intuitively working remote control operating unit having a first pair of control elements for controlling a movement of a hoist, in particular a trolley of a crane, in two opposite movement directions along an axis, with one control element assigned separately to one movement direction and the other control element assigned separately to the other opposite movement direction, wherein the control elements are so disposed as to form a side-correct representation of the movement directions, and wherein assignment of the control elements to the movement directions corresponds to an orientation of the operating unit in relation to a directed external field and is swapped, when the operating unit is oriented in opposite direction.
The control system of claim 10, wherein the operating unit includes at least one of a signaling unit for outputting a message and a blocking mechanism for suppressing operation of the operating unit, when the assignment of at least one control element relative to a movement direction is no longer unambiguously clear.
