Knoedler Ergo Series 600 "a cheaper alternative" A modestly priced, efficient armrest specially designed for buses, trucks, lorries and forklifts, in other words for working environments that do not require a control lever holder on the armrest. However, there is no problem in equipping the "Knoedler Ergo 600" with a lever holder for light electrical joysticks. The armrest is easy to adjust vertically, by means of a knob and also has a pad (cushion) that can be tilted and turned. This means that the driver can always adjust the pad to a position where all of his/her forearm lies comfortably on it. The "Knoedler Ergo 600" can be raised to and locked in a vertical position. The pad is available in three different sizes: 275 x 90 mm., 300 x 130 mm. and the new "S"-pad is also available.
