A control system (1) for earth moving or working apparatus (14) such as an excavator comprises a first control arm (4), a second control arm (10) and an end member (12), pivotally connected to as to emulate the working arms (16, 17) and bucket (18) of the excavator. The first and second control arms (4, 10) are provided with handles (8, 11) projecting laterally outwards in opposite directions so that the positions of the first and second control arms can be altered by a user. The handle (11) on the second control arm (10) can also be twisted to control movement of the end member (12). These movements are translated into control of hydraulic actuators (18, 19, 20) for controlling the working arms (16, 17) and bucket (18) of the excavator. The control arms (4,10) can be moved to a position in which the handles (8, 11) are axially aligned, for steering of the excavator (14) during transit. The control system (1) maybe detachable from the excavator (14). Haptic feedback may be provided. |
