Abstract (en)
Two multi-axis joysticks (23,24), one horizontal and the other upright, provide the operator of a material handling vehicle with an intuitive control interface to the vehicle (34). The control system (10) also provides a coordinated control for spatial placement of the working device (14) of the work implement (11). Movement up and down and in and out being controlled by the horizontal joystick (23) as is the movement of the working device (14) relative to its adjacent linkage (13). Swinging movement about an upright axis is controlled by the second joystick (24).
